VMware Cloud Foundation — Enhanced Data Path

2×

network throughput potential

In today's enterprise environments, the network is no longer just plumbing it is the performance ceiling for every workload running on VMware Cloud Foundation. The question practitioners keep asking: how do you get the most out of VCF networking, diagnose problems before they become incidents, and squeeze every last bit of throughput from the stack?

The answer begins with understanding a component that many administrators may not yet have fully explored: the Enhanced Data Path (EDP).

"A performance focused datapath doesn't just help heavy hitters it raises the floor for every workload in your environment."

The Core Concept

What is Enhanced Data Path?

VMware Cloud Foundation ships with multiple host switch modes, and EDP sits at the top of the performance tier. Unlike the standard networking stack, EDP is engineered to minimize latency and maximize throughput by taking a more direct route through the host's data plane.

EDP achieves this partly by dedicating a fixed portion of CPU resources exclusively to network processing a tradeoff that delivers consistent, predictable performance for latency-sensitive and throughput-intensive workloads. Understanding this tradeoff is essential before you enable or tune it.

Standard

EDP Standard

The recommended starting point for most enterprise workloads. Delivers significantly improved performance over the legacy stack without requiring manual resource reservations or deep analysis.

Dedicated

EDP Dedicated

Designed for applications with stringent, near-line-rate requirements. Reserves CPU cores strictly for network processing demands careful capacity planning upfront and ongoing tuning as workloads evolve.

The right choice depends on your workload profile. Under-provisioning EDP Dedicated can paradoxically hurt performance, while over-provisioning starves application VMs of the CPU cycles they need. A thorough analysis before deployment is non-negotiable.

Getting Started

Checking and enabling EDP

One of the most common questions practitioners encounter: "Is EDP already running on my cluster?" The answer often surprises many production environments are still on the legacy datapath simply because no one checked. Here's how to verify and act:

Navigate to your NSX host switch configuration and identify the current datapath mode assigned to each transport node.
If still on the legacy stack, evaluate your workload density and CPU headroom before planning a migration to EDP Standard.
For EDP Dedicated, model your CPU allocation — the cores reserved for network processing cannot serve VMs, so right-sizing is critical.
Validate the change in a non-production environment first, then roll out host by host to minimize blast radius.

Visibility & Ops

Monitoring the network health of your applications

Enabling EDP is only half the journey. Continuous monitoring not just of raw throughput, but of application-centric network health — is where organizations separate reactive fire-fighting from proactive operations. VCF Operations for Networks provides the observability layer that ties it all together.

Flow metrics & counters

The NSX API exposes Network Datapath and Enhanced Datapath host switch counters for granular per-host visibility into real traffic patterns.

Baseline vs. anomalies

Machine learning-driven guided troubleshooting visualizes all inter-related topology variables and flags deviations from established baselines.

Latency & throughput KPIs

The Network Operations view surfaces dropped-packet monitoring, IOPS, throughput, and latency for every NSX transport node in your topology.

App-centric validation

Verify traffic paths, firewall health, and ACL correctness for specific VMs, applications, and containers not just fabric-level health.

When Things Go Wrong

A systematic approach to troubleshooting

When applications start complaining about the network, the instinct is to look everywhere at once. A structured path works better: start at the host, move toward the overlay, then toward the application.

For EDP environments, a key early check is CPU saturation on network-dedicated cores. If those cores are pegged, no amount of fabric tuning will help you need to either rebalance workloads or revisit your EDP Dedicated CPU reservation. The esxtop utility remains one of the most powerful tools for real-time host-level visibility, exposing CPU, memory, disk, and network resource utilization in one place.

"Before you tune, you must see. Instrumentation is not optional ,it is the foundation of every performance conversation."

Beyond the host, guided network troubleshooting in VCF Operations for Networks uses machine learning to map relationships and dependencies, detect anomalies, and surface hints about root causes cutting mean-time-to-resolution dramatically compared to manual log correlation across multiple consoles.

Key Takeaways

What to do when you get back to your desk

Audit your current host switch mode many clusters are still on the legacy datapath and can benefit immediately from a migration to EDP Standard.
Enable Enhanced Datapath host switch counters via the NSX API to establish a performance baseline before making any changes.
If you are running latency-sensitive workloads, model CPU requirements for EDP Dedicated before deployment then monitor continuously as workload mix evolves.
Invest in VCF Operations for Networks as your monitoring layer; the guided troubleshooting capability alone can save hours per incident.
Treat performance tuning as an ongoing process, not a one-time project. EDP Dedicated in particular requires regular review as workloads grow.

From vSphere 8 to VCF 9.x Upgrade with No Spare Hosts : The Consolidated Domain Path with DR Strategy Design

2026-04-03T11:19:00.016+05:30

Technical Architecture

From vSphere 8 to VCF 9.x Upgrade with No Spare Hosts : The Consolidated Domain Path with DR Strategy Design.

A practical guide to adopting VMware Cloud Foundation 9.0.2 in a brownfield, two-site environment when dedicated management hardware is not an option.

Sachin Bhardwaj

Principal Architect · April 2026

The challenge

Every customer who considers VCF 9 eventually hits the same question: where do I put the management VMs? The standard guidance calls for a dedicated management domain — a separate cluster of hosts running nothing but SDDC Manager, NSX, vCenter, and the VCF Operations stack. For a greenfield deployment that is straightforward. For a brownfield vSphere 8 environment at capacity, it is a capital expenditure problem that can stall an entire modernisation programme.

The scenario this post addresses is deliberately constrained: a production vSphere 8 environment across two sites, no spare hosts, no NSX deployed, no Layer 2 stretch between sites, and a firm requirement that all management appliances are protected across sites. Broadcom's answer to this constraint is the Consolidated Domain architecture and it is more capable than most customers expect.

Consolidated Domain defined: A single VCF domain where management VMs and workload VMs share the same physical ESXi hosts, separated by vSphere DRS resource pools with reservations. No dedicated management hardware is required. This is a fully supported deployment model in VCF 9.0.2.

Two-site architecture overview

The design below deploys one VCF Instance per site : Instance A at Site A (primary/protected) and Instance B at Site B (recovery). Both instances are registered under a single VCF Fleet, giving unified lifecycle management across all hosts from one VCF Operations pane & VCF Automation.

No L2 stretch · No NSX overlay · SRM IP customisation rules handle re-IP on failover

Management appliance protection tiers

This is the most critical design decision and the one most commonly misunderstood. Not all management VMs can or should be SRM-protected. The tier is determined by the VM's architecture, not by preference.

Tier 1 : VMware Live Recovery

VCF Operations Fleet Manager Ops for Logs Ops for Networks

How it works: vSphere Replication continuously replicates these VMs from Site A to Site B. SRM orchestrates power-on order and applies IP customisation rules at failover Site B uses different subnets and there is no L2 stretch, so every VM receives a new IP via VMware Tools guest customisation. DNS must be updated post-failover. Boot order: VCF Operations powers on first, then Fleet Manager, then logging and network visibility.

Tier 2 : Backup and Restore

VCF Automation

How it works: A daily SFTP file-based backup is taken. At Site B failover, a fresh VCF Automation instance is deployed and the latest backup is restored into it. No vSphere Replication is used. This is per Broadcom VCF 9 Validated Solution VCF Automation is not SRM-protected.

Tier 3 : Independent per site

vCenter (each site) SDDC Manager (each site) NSX Managers ×3 (each site) Identity Broker (each site)

vCenter: Cannot be SRM-protected — SRM runs inside vCenter and cannot protect the host it runs in. Site B's vCenter is always independently operational. VAMI file-based backups taken daily to SFTP for local recovery if Site B's vCenter itself fails.

SDDC Manager: Each site has its own instance. Daily SFTP backup. If Site B's SDDC Manager fails, restore from backup after vCenter is confirmed operational — sequential dependency.

NSX Managers ×3: VLAN-only mode is deployed (no overlay transport zone on workload clusters). Each site's NSX Managers serve only their own VCF instance. No cross-site NSX sharing. No TEP VMkernel on any workload host 1500 MTU preserved.

Identity Broker: Stateless federation broker. Identity lives in your Active Directory, not in the broker. Site B's Identity Broker was already pointing at the same AD and continues serving Site B components when Site A fails. After VCF Operations fails over to Site B, re-register VCF Operations with Site B's Identity Broker — a five-minute runbook step.

Key design considerations

Resource isolation

DRS resource pools with reservations and limits keep management VMs from competing with production workloads. vSphere HA automatically restarts management VMs on surviving hosts.

Host count minimum

VCF 9.0.2 requires a minimum of 3 hosts for the management cluster with FC/VMFS storage down from 4 in VCF 5.x. Two hosts is the minimum for workload domain import.

No NSX overlay required

NSX is mandatory in VCF 9 but VLAN-only mode is fully supported. No TEP VMkernel, no GENEVE encapsulation, no MTU changes on workload clusters.

SRM without L2 stretch

SRM Network Mappings and IP Customisation Rules handle all VLAN and subnet differences between sites. This is the standard SRM routed DR model, no L2 extension required.

Storage replication

Array-based replication (e.g. Pure Storage SnapMirror) feeds SRM protection groups. NetApp SRA maps datastores via SnapMirror relationships. LUN IDs at Site B do not need to match Site A.

Brownfield convergence

The VCF Installer convergence wizard takes your existing vCenter, ESXi hosts, and NSX as inputs. Your vCenter is not replaced — it becomes the management domain vCenter.

What this design delivers

By the end of the deployment programme, the organisation has a unified VCF 9.0.2 fleet managing both sites from a single VCF Operations console, fully automated lifecycle management for all management appliances, bi-directional SRM protection with tested recovery plans, and centralised log collection via VCF Ops for Logs all without purchasing a single additional physical server.

Recommended approach: Do not run VCF convergence and pre-convergence remediation as parallel tracks. Complete HCI cluster remediation, DVS upgrades, and NSX 4.2.1 installation as Phase 0 and Phase 1 blockers. Once those are clean, the VCF Installer convergence is typically a single-day event per site.

VCF9 : VMware Identity Broker (VIDB) in VCF 9.x: Architecture, Design, and Real-World Behavior

2026-01-19T22:59:00.032+05:30

Introduction

With the evolution of VMware Cloud Foundation (VCF) 9.x, Broadcom introduced several foundational platform changes aimed at improving security, scalability, and lifecycle consistency across private cloud environments.

One of the most critical yet frequently misunderstood components is VMware Identity Broker (VIDB).

This article provides an end-to-end, practical understanding of VIDB, covering:

Why VIDB exists and the problem it solves
How VIDB works internally
Where VIDB is deployed in VCF
High availability and security design
Multi-site architecture (Site 1 / Site 2)
Embedded or on HA-Cluster?
Operational behavior and lifecycle management
Common misconceptions and pitfalls
FAQ explanations

This guide is written for architects, consultants, and advanced VCF practitioners who want clarity—not marketing.

What Is VMware Identity Broker (VIDB)?

VMware Identity Broker (VIDB) is a centralized identity federation and trust-broker service introduced with VCF 9.x.

In simple terms:

VIDB acts as a secure intermediary between your enterprise identity provider (AD / SAML / OIDC) and VCF platform services, ensuring those services never directly integrate with enterprise identity systems.

VIDB is not optional, not add-on, and not configurable outside supported workflows. It is a core VCF platform service.

Figure:1

Why VIDB Was Introduced (The Real Problem It Solves)

Before VIDB (Legacy Model)

Each VCF component integrated directly with Active Directory
Tight coupling between identity and platform services
Complex upgrades and rollback risks
Inconsistent authentication behavior
Expanded security attack surface

After VIDB (VCF 9.x Model)

Single, centralized identity entry point per VCF instance
Decoupled identity architecture
Platform-managed lifecycle
Consistent authentication and RBAC behavior
Stronger security boundaries

VIDB is not a feature—it is a foundational platform service.

Figure:2

Where Is VIDB Deployed?

VIDB is deployed:

Only in the Management Domain
Automatically during VCF bring-up or convergence
Managed exclusively by VCF Lifecycle Manager
Never deployed in workload domains

Treat VIDB exactly like SDDC Manager—a protected, platform-level service.

Figure:3

Each VIDB deployment consists of:

Three stateless VIDB nodes
One Virtual IP (VIP)
Three IP's for nodes

Why Four IP Addresses?

VIP	: Stable endpoint for all VCF services
Node 1	: Active VIDB instance
Node 2	: Redundant instance
Node 3	: Redundant instance

Figure:4

This design enables:

No single point of failure
Transparent failover
Rolling upgrades
Zero-downtime maintenance

Shall I deploy VIDB as Embedded or with HA-Cluster.....

Deploying VIDB as Embedded or with HA-Cluster depends where you are deploying. Let's discuss:

Embedded : Its good for POC / Lab and very small environment where one can tolerate a simple availability model.

HA Cluster: When identity is mission-critical and you need higher resiliency + maintenance flexibility.

Authentication & Token Flow (Step-by-Step)

Figure:5

User accesses a VCF UI or API
Request is redirected to the enterprise IdP
IdP authenticates user (password + MFA)
Assertion is returned to VIDB
VIDB validates trust and policies
VIDB issues a short-lived token
VCF service consumes the token
RBAC is enforced locally

Tokens are short-lived, site-local, and instance-scoped.

Multi-Site Design (Site 1 / Site 2 Best Practice)

Figure:6

Scenerio

Site 1 → VCF Instance A
Site 2 → VCF Instance B
Shared enterprise identity provide.

Correct Architecture:

One VIDB per VCF instance
No cross-site VIDB usage
No stretched identity services

Why This Matters:

Failure isolation
Independent upgrades
Low-latency authentication
Fully supported design

VIDB is never stretched across sites.

Security Benefits of VIDB

No credentials stored in VCF services
Certificate-based trust
TLS-secured communication
Short-lived tokens
Reduced attack surface

This design aligns VCF identity with zero-trust principles.

Lifecycle Management

VIDB lifecycle is:

Fully automated
Rolling and non-disruptive
Managed entirely by VCF LCM
Not manually patchable or configurable

Each VCF instance upgrades its VIDB independently.

Frequent Asked Question (FAQ)

Where is VIDB Deployed?

VIDB is deployed in the Management Domain and managed as a platform service by VCF. It is not supported in workload domains.

Why does VIDB require three nodes?

Three stateless nodes provide high availability, prevent split-brain scenarios, and allow rolling upgrades without downtime.

Why four IP's?

Three IPs for the nodes and one VIP as a stable access endpoint for all VCF services.

Where is MFA enforced?

At the enterprise identity provider. VIDB only brokers trust and tokens.

What happens if a VIDB node fails?

No impact. Traffic continues through the VIP to remaining healthy nodes.

VCF 9 (VMware Cloud Foundation 9) Networking Explained: Designing (VPC) Virtual Private Cloud.

2025-12-23T13:57:00.009+05:30

Networking takes a quantum leap toward isolation and self-service with VCF 9, as VMware introduces Virtual Private Clouds. This is natively built on NSX, thereby redefining multitenant, secure, and scalable networking for enterprise private clouds.

credit: Broadcom

The focus of this article is specifically VCF 9 networking with VPCs: what they are, how they work, and why they matter from an architect's perspective.

What is a VPC in VCF 9......

With VCF 9, a VPC in VMware is a logically isolated networking construct in NSX that provides:

Strong tenant isolation
Independent IP addressing
Decentralized ownership of networking
Secure, scalable application connectivity

Think of a VPC as a private cloud inside your private cloud-very much along the lines of AWS or Azure VPCs, but full-on-prem and NSX-driven.

Why VMware did introduce VPCs in VCF 9?

Traditional NSX designs relied on Shared Tier-0/Tier-1 topologies, which worked-but scaled poorly for large enterprises and service providers.

VPCs solve this by enabling:

• Multi-tenancy without sprawl

• Application-centric networking

• Clear segregation of duties between platform and tenant teams

• Public-cloud operational parity

Core VPC Building Blocks

1. Projects

The Project in a VPC is a logical container used to isolate, organize and delegate network resources for specific team, application or tenant.

credit:Broadcom

Owned by a tenant, BU, or application team
Define quotas, including: IP blocks, subnets, security objects
Provides the control plane for VPCs

2. Virtual Private Cloud (VPC)

Within a Project, you create one or more VPCs where :

Each VPC is its own routing domain
There is no route leakage by default
Full east-west isolation between VPCs unless explicitly allowed.

3. VPC Subnets

VCF 9 supports three subnet types, each with a particular role:

VPC Private Subnet

For internal application tiers: Web/App/DB
No direct external connectivity.
Protected by Distributed Firewall - DFW

Public Subnet

Provides north-south access
Bastion hosts, LB VIPs Public-facing applications
Connectivity controlled via NSX Gateway Firewall

Private Transit Subnet (Very Important)

Used for external connectivity via NAT
Required when outbound/inbound access is required for VMs using external IPs
Misunderstood often, critical for architecture.

Key point: in VCF 9, the External IPs can be attached to workloads connected to Private Transit Subnets only, and not the regular private subnets.

Routing & Connectivity Model:

North–South Traffic

credit:Broadcom

VPC traffic exits via Project-scoped gateways
NAT and firewall policies applied at VPC edge
Underlay connectivity still leverages NSX Edge and Tier-0, abstracted away from tenants.

East–West Traffic

Enforced via DFW

• Policies can be: IP-based, Group-based or Context Profile L7 based.

• Zero-trust is the default design posture

VPC Networking Security Benefits

VPCs are much improved in terms of security posture:

Hard isolation between tenants.
Microsegmentation by default.
Independent firewall rule sets per VPC.
Blast radius in case of a breach or misconfiguration reduced.

VPCs make it far easier, from a compliance standpoint, to align with

PCI-DSS
ISO 27001
Zero-Trust frameworks

Operational Model: Platform versus Tenant Teams

The strongest point about VPCs in VCF 9 has to do with operational clarity:

Platform Team (Central IT)

Leading NSX fabric, Edge, and Tier-0 management.
Enforces project and quota definitions.
Owns the Lifecycle and Upgrades.

Tenant / App Team

It creates VPCs and subnets.
Manages the rules in FireWall.
Networking as a service is being consumed end.

This separation is the biggest win of all for large enterprises and service providers.

VPC vs Traditional NSX Design

Aspect	Traditional NSX	VCF 9 VPC
Isolation	Logical	Strong tenant-grade
Scalability	Limited	High
Ownership	Central IT	Shared / Self-service
Cloud parity	Low	Very high
Security model	Add-on	Built-in

My last thought on this.....

VCF 9 VPC networking is more than just a feature: it's actually a basic architectural shift. It is changing NSX from a shared enterprise network to a real private-cloud networking platform aligned with modern app and security models. If you're designing, operating, or demonstrating VCF 9 then VPCs should be at the core of your networking strategy.

VCF9 Building Infrastructure for POC and LAB enviornment

2025-11-22T13:09:00.004+05:30

The VMware ecosystem has undergone some of its biggest transformations in recent years, and one of the most significant milestones is the Broadcom-backed release of VMware Cloud Foundation (VCF) 9. This latest version introduces a modernized architecture that dramatically expands flexibility across both storage and networking layers—giving architects more freedom than ever to design environments that align with real-world operational and business requirements.

On the storage front, VCF 9 removes the long-standing dependency on vSAN as the mandatory principal storage. Organizations can now deploy Management and Workload Domains using NFS or Fibre Channel (FC) in addition to vSAN HCI (ESA/OSA). Supplemental storage options also expand, with support for iSCSI, NVMe, and vSAN Remote, enabling hybrid use cases and smoother brownfield integrations.

Networking sees an equally impactful shift. VCF 9 introduces Edgeless Networking for overlay, eliminating the need to deploy NSX Edge Nodes for east-west overlay connectivity. This not only simplifies deployment and reduces infrastructure overhead but also aligns better with modern data center fabrics like EVPN, ACI, and Arista environments where north-south routing is handled externally.

Overall, VCF 9 marks a major step toward a more open, flexible, and operations-friendly SDDC platform setting a strong foundation for scalable, modern cloud infrastructure.

Coming to the actual discussion to deploy the VCF 9 on Single ESXi or or Max 2. Here is the workaround you could apply.

1) Get the VCF Installer Downloaded from Broadcom portal which is actually reqjuired for every VCF deployment which is quite common.

2) Now, when you configure only 1 host into the VCF installer to deploy the VCF 9 its genuenly give you and error as you are not fullfiling the 3 host requirement in case of FC due to the hardcoded requirment set in VCF Installer.

All of this sounds great on paper—but the practical question many architects have is: “Can I actually run VCF 9 in my home lab, given its traditionally large footprint?”

Surprisingly, the answer is yes. You can deploy and explore VCF 9 in a home lab using just one or two ESXi hosts—but it does require a few tweaks and workarounds.

Under normal circumstances, the VCF 9 installer enforces the standard minimums:

3 ESXi hosts when using vSAN (ESA/OSA)
2 ESXi hosts when using NFS or FC

These values are perfectly valid for lab and PoC environments, but production deployments will require more hosts to meet HA, resiliency, and sizing best practices.

Now, coming to the actual topic—running VCF 9 on a single ESXi host or a maximum of two.
This is achievable, but you need to apply a specific workaround.

Steps Overview:

1) Download the VCF Installer
Start by downloading the VCF Installer bundle from the Broadcom portal, which is required for every VCF deployment.

2) Understand the Installer Limitation
If you attempt to configure VCF 9 with only a single ESXi host in the installer, you’ll immediately receive an error—because the host count check is hardcoded to validate a minimum of 3 hosts (for vSAN) or 2 hosts (for FC/NFS).

To bypass this, a small configuration modification is needed, which allows the installer to proceed even with a 1-node setup.

3) To bypass the hardcoded host-count validation in the VCF Installer, you need to add a feature flag inside the Cloud Builder appliance. Run the following command:


>> echo "feature.vcf.vgl-29121.single.host.domain=true" >> /home/vcf/feature.properties

4) For VCF 9 specifically, append the internal single-host deployment flag:


>> echo "feature.vcf.internal.single.host.domain=true" >> /home/vcf/feature.properties

5) Once the feature flags are added, restart the VCF Installer services so the changes take effect:


>> echo 'y' | /opt/vmware/vcf/operationsmanager/scripts/cli/sddcmanager_restart_services.sh

6) After the services restart successfully, you can proceed with the VCF 9 installation using your 1-node or 2-node configuration.

Important Note

This workaround is intended only for lab and PoC environments. It is not officially supported by Broadcom, and you should not rely on this method for production deployments.

Additionally, ensure that your home lab meets the minimum CPU, memory, and storage requirements needed to run the VCF components successfully.

VCF 9 - Automating the VCF Support logs using Log Assist Feature

2025-11-18T18:46:00.032+05:30

In IT infrastructure, support engineers handle a wide range of daily activities—maintaining, sustaining, and troubleshooting systems. At times, they also face complex bugs or advanced issues that require assistance from product support teams.

In this scenario, we’re using VCF as the example product a tightly integrated solution composed of multiple components working together to deliver its capabilities.

Let’s walk through a short story to understand the root cause of an issue and how it was resolved:

A support engineer named Vivek was working on importing a vCenter instance into a VCF 9 environment. During this process, he encountered a challenging error within VCF Operations that he was unable to resolve on his own.

Realizing he needed help, Vivek opened a support request with Broadcom. The support team asked him to provide the necessary log bundles for analysis. Vivek downloaded the requested logs locally and uploaded them to the Broadcom portal a task that took considerable time. Unfortunately, Broadcom later informed him that the uploaded logs were corrupted and asked him to repeat the process. This repeated effort consumed several productive hours, leaving Vivek frustrated.

Determined to find a better way, Vivek began researching and discovered a feature called Log Assist—the successor to one of his previous favorite tools, VMware Skyline.

Log Assist is a built-in capability in VCF 9 that automates the collection and upload of logs directly to Broadcom, eliminating the need for manual downloads or uploads. This significantly reduces operational overhead and allows support engineers to focus on actual troubleshooting rather than time-consuming log handling.

Now that we have a basic understanding of Log Assist, let’s look at what is required to enable and use it in a VCF 9 environment. Note that this feature is available only from VCF 9.0 onward.

Prerequisites for Enabling Log Assist in VCF 9

VCF Operations Deployment
The VCF Operations appliances must be deployed in the environment.
Unified Cloud Proxy
A Unified Cloud Proxy must be installed and configured. It acts as the secure communication bridge between the on-premises VCF environment and Broadcom Cloud Services.
VCF Operations for Logs
VCF Operations for logs must be integrated with the vCenter instance, licensed with VCF or VMware vSphere Foundation (VVF) version 9 or later.
Network Connectivity
The Unified Cloud Proxy must have outbound HTTPS connectivity (port 443) to Broadcom Cloud Services (eapi.broadcom.com), as well as access to VCF endpoints such as vCenter and ESXi hosts.

Now, As we had discussed about the requirement of technical requirement to enable "Log Assist" Feature.

Lets begin with Deployment and configuration steps:

Step 1: Download "Unified Cloud Proxy OVA" from Broadcom support Site.

Step 2: Login to VCF Operation > Administrator > Cloud Proxies

Step 3: Click on ADD under "Cloud proxies" section

Step 4: Copy the Unique registration key which is at #5 for future reference " This will be required during deployment of Unified Cloud proxy OVA installation"

Step 5: Installation of Unified Cloud proxy:

Deploy the Unified Cloud proxy OVA on Managment vCenter

Note: Make Sure you select "Unified Cloud Proxy" During deployment and select size as per your environment.

Step 6: Once the Unified Cloud proxy installation completed please validate it should say connected to VCF operation. It may take 5-10 min to get the connectivity. So please be bit patience.

Step 7: Once the Cloud proxy is well connected to VCF Operation follow below steps:
Administration > Cloud Proxies: Here you will see your newly Cloud proxy vm showing with status" Online" with Type " Unified"

Note: As I have already activated my CloudUnified Proxy, thats the reason its showing as "Activated" . However, initially you need to Activate it using below option

Select the Cloud Proxy > Click on 3 dots > Activate Log Assist

Step 8: Now, its time integrate your Unfied Cloud proxy with associated components like VCF, vCenter and others.

For that Go to Administration > Integrations > Accounts > ADD > VCF or NSX or vCenter

Here we adding VCF as an account type:

>Populate the VCF details

>Collector /Group : Select the Unified Cloud Proxy

Like this you could add other Account type like vCenter, NSX and others.

Step 9: Now its time to access the LogAssist Feature:

Click on "Prepare A Transfer" to upload logs using "Log Assist"

Select the inventory for which you would like to generate and ship the logs to Broadcom support.

Here i have selected the VCF operations logs to be shipped.

Here, log assist will validate and confirm the connectivity

Add active Broadcom Support case ID and click > TRANSFER

Logs starting initiating > Downloading and processing..

Logs download and shipping got completed in just 4 minutes. But again it depends on logs size.

Using "Log Assist" greatly simplifies the support engineer's workflow and eliminates unnecessary los of productive hours.

Hope you found this article useful.

VCF 9 Networking : Centralized vs Distributed Connectivity

2025-10-11T09:31:00.006+05:30

VCF 9 Networking : Centralized vs Distributed Connectivity

With the release of VMware Cloud Foundation 9 (VCF 9.0), VMware has redefined the private cloud networking model by introducing both centralized and distributed connectivity. This dual approach provides flexibility for organizations to choose between traditional edge-based routing and modern, host-level distributed networking.

Why New Networking in VCF 9?

Prior to VCF 9, NSX networking was largely edge-centric—requiring dedicated Edge clusters to handle north-south traffic. This created scaling and operational overheads. VCF 9 introduces a cloud-like networking abstraction with:

Native VPCs (Virtual Private Clouds) for tenant isolation.
Transit Gateways (TGW) to interconnect VPCs and external networks.
Simplified bootstrapping – NSX VIBs are embedded in ESXi for easier enablement.
Improved lifecycle and visibility via integrated VCF Operations.

These enhancements align with VMware’s goal of offering public cloud simplicity with private cloud control.

Core Building Blocks

Virtual Private Cloud (VPC)

Each VPC provides isolated networking for workloads. Users can create subnets, security groups, and routing policies.

Transit Gateway (TGW)

TGWs act as the backbone of connectivity, linking multiple VPCs and connecting to external or on-prem networks.

External Connectivity Models

VCF 9 offers two approaches for north-south traffic:

Centralized (CTGW) – traffic flows through NSX Edge clusters.
Distributed (DTGW / Edgeless) – routing happens at the ESXi host level.

Centralized (CTGW) Connectivity

In the centralized model, external traffic exits via NSX Edge VMs hosting Tier-0 Gateways.

Workflow:

VPC traffic routes to TGW.
TGW connects to Tier-0 gateway on Edge Cluster.
Tier-0 peers (BGP/static) with physical routers.

Advantages:

Centralized control and policy enforcement.
Ideal for complex routing and multi-WAN setups.
Easier integration with existing NSX Edge-based services (NAT, LB).

Limitations:

Higher latency (additional Edge hop).
Resource overhead of Edge clusters.
Possible bottlenecks under heavy traffic.

Illustration:

Distributed (DTGW / Edgeless) Connectivity

The distributed model removes the dependency on Edge VMs. Each ESXi host becomes capable of directly routing external traffic.

Workflow:

TGW maps to a VLAN connected to the physical network.
Each host handles north-south routing directly.
Network services (NAT, firewall) are distributed at the host level.

Advantages:

Lower latency and improved performance.
No need for dedicated Edge nodes.
Simpler and more scalable for lightweight or edge deployments.

Limitations:

Less centralized visibility.
Some advanced services may still need Edge nodes.

Comparison Table

End-to-End Flow Example

Project Admin defines a Transit Gateway (TGW).
VPC Admin creates VPCs and subnets.
VPC traffic flows to TGW.
TGW connects to either:
- Tier-0 Gateway (centralized)
- VLAN uplink (distributed)
External IPs and BGP peering complete the setup.

Visual Flow:

When to Choose Each Model

Hybrid adoption is also supported—some domains can run centralized edges while others leverage distributed exits.

Extract:

VCF 9 unifies NSX networking into a modern, VPC-driven model.
Distributed networking simplifies infrastructure for smaller or edge environments.
Centralized networking remains relevant for policy-rich or complex routing needs.
Together, they deliver flexibility, scalability, and cloud-like networking agility.

Resources good to have on this

Thanks for the reading . Happy learning 😊

Key New vSAN Features in VMware Cloud Foundation (VCF 9.0)

2025-08-14T00:06:00.007+05:30

The release of VMware Cloud Foundation (VCF 9.0) brings one of the most significant evolutions in vSAN to date—delivering performance, efficiency, and flexibility enhancements tailored for today’s demanding workloads. With data growth accelerating and enterprises embracing AI, analytics, and hybrid cloud strategies, storage platforms must do more than just store bits—they must accelerate innovation, protect critical assets, and optimize resource usage.

In VCF 9, vSAN introduces breakthrough capabilities like cluster-wide global deduplication, native vSAN-to-vSAN replication with deep, immutable snapshots, and major data path performance optimizations. Combined with ESA’s blistering IOPS performance, advanced memory tiering, and greater storage architecture flexibility, these features address modern enterprise needs ranging from AI/ML pipelines to cyber-resilient disaster recovery.

In this article, we’ll explore the most impactful new vSAN features in VCF 9, why they matter for architects and IT leaders, and how they can transform your cloud foundation into a future-ready storage powerhouse.

Global Deduplication

vSAN ESA in VCF 9.0 introduces software-based, cluster-wide deduplication that identifies and removes redundant 4KB blocks across the entire cluster, not just per disk group, significantly improving data reduction efficiency.
The deduplication engine is post-process and opportunistic, running in the background using free CPU cycles to minimize impact on foreground workloads and latency.

Broadcom states potential storage reduction up to 8x, depending on data characteristics, materially shrinking storage footprint and lowering overall TCO.
The feature is available with vSAN ESA in VCF 9.0 P01 and, at launch, has specific scope and limitations (e.g., limited availability via RPQ/approved requests and environmental prerequisites)

vSAN-to-vSAN Replication with Deep Snapshots

VCF 9.0 adds native, asynchronous vSAN-to-vSAN replication built on vSAN Data Protection, enabling remote replication of vSAN snapshots to any vSAN ESA datastore (HCI or disaggregated).
Replication supports immutable, crash-consistent deep snapshots with histories up to 200 snapshots per-VM, enabling cyber recovery workflows that can roll back to clean points in time.

Integration with VMware Live Recovery provides full DR orchestration, low RPOs (as low as 1 minute), simplified lifecycle with a single appliance, and more efficient failover/failback at the VM level instead of array LUNs.

Enhanced Data Path Performance

VCF 9.0 includes platform networking and data path enhancements, including options for NSX Enhanced Data Path that can deliver up to 3x switching performance, lowering latency and CPU overhead for high-throughput workloads.

These enhancements benefit chatty microservices and data-intensive pipelines by reducing network bottlenecks and improving end-to-end throughput.

Support for Modern AI and Memory-Intensive Workloads

vSAN ESA continues to deliver up to 300,000 IOPS per node with consistent sub-millisecond latency, with performance and capacity scaling linearly as the cluster grows, aligning to AI/ML and other latency-sensitive workloads.

Advanced Memory Tiering (vSphere feature in VCF 9) is production-ready and improves effective memory capacity and consolidation via DRAM–NVMe tiering, increasing CPU utilization and VM density for memory-heavy applications.

Flexible Management Domain Storage

In VCF 9.0, organizations gain flexibility to use alternative primary storage for the Management Domain beyond vSAN, such as FC or NFS, aligning storage choices with existing investments and operational preferences.

Improved Storage Cluster Networking

Storage cluster networking can be separated from compute networking in VCF 9.0, enabling independent optimization of network resources and better utilization of existing network infrastructure for compute traffic.

Why These Matter

Global dedupe reduces storage cost without materially affecting performance, especially valuable at scale and with redundant datasets typical in VMs and container images.
Native vSAN replication with deep, immutable snapshots plus Live Recovery orchestration enables granular VM-level cyber/disaster recovery with deeper restore points and faster, simpler recovery paths than array/LUN workflows.

Data path and networking gains, combined with ESA’s high IOPS/low-latency profile and memory tiering, support modern AI/ML and microservice workloads with predictable performance at scale.

Notes for my fellow Architects

Global dedupe is ESA-only and cluster-wide; plan capacity and CPU headroom for background post-process operations and confirm environmental prerequisites during early adoption phases.
For cyber recovery, align snapshot retention (up to 200 per VM) with ransomware dwell-time assumptions and integrate with isolated recovery environments via Live Recovery where sovereignty requires on-premises recovery.
Consider networking separation and NSX Enhanced Data Path to reduce contention and achieve higher throughput for storage and east–west application traffic.

Integrated Deployment of Nutanix AOS and AHV

2025-06-12T00:26:00.011+05:30

The Nutanix platform employs a unified installation approach where AOS and AHV are deployed simultaneously through a single Foundation installation process. This integrated architecture eliminates the need for separate installation procedures, as both components are designed to function as interdependent elements of a cohesive hyperconverged infrastructure system.

Nutanix AOS and AHV integrated architecture and deployment process

The Controller Virtual Machine (CVM) represents the primary mechanism through which AOS operates within the AHV environment.

In AHV deployments, the CVM runs as a specialized virtual machine with direct hardware access through PCI passthrough technology, allowing AOS to maintain direct control over storage devices while operating within the virtualized environment provided by AHV.

Detailed Installation Flow Process

Nutanix AOS and AHV Installation Flow Diagram - Complete Deployment Process

The deployment process consists of four distinct stages that demonstrate the integrated nature of the Nutanix platform:

Stage 1: Foundation Tool Initialization

Foundation is the official deployment software of Nutanix that allows the configuration of pre-imaged nodes or imaging of nodes with both hypervisor and AOS together. The Foundation process begins with node discovery and hardware validation, followed by IP address assignment for IPMI, hypervisor, and CVM interfaces. This stage establishes the groundwork for the unified installation process that will deploy both AHV and AOS simultaneously.

Stage 2: Installation Phase

During this critical phase, the Foundation process installs AHV as the bare-metal hypervisor while automatically provisioning the Controller Virtual Machine, which runs AOS. The installation specifically configures AHV as the hypervisor layer while simultaneously deploying the CVM with AOS functionality.

For Nutanix units running AHV, the SCSI controller, which manages the SSD and HDD devices, is directly passed to the CVM through PCI passthrough, enabling AOS to handle all storage management functions.

Stage 3: Bootstrap Process

When AHV boots, it automatically starts the CVM, which then initializes AOS and begins managing the storage pool and cluster services. This automatic startup sequence demonstrates the tight integration between the hypervisor and operating system layers, ensuring that storage services are available immediately upon system initialization. The bootstrap process includes cluster formation and storage pool creation, establishing the distributed storage fabric that characterizes Nutanix architecture.

Stage 4: Integration and Validation

The final stage establishes communication between AHV and the CVM, activates the Prism management interface, and validates all storage services. This integration phase ensures that both hypervisor and storage capabilities are accessible through the unified Prism management interface, eliminating the complexity typically associated with managing separate hypervisor and storage management systems.

Key Integration Points

The flow diagram illustrates several critical integration points that demonstrate why AOS does not require separate installation on AHV:

Unified Management: AHV is native to the Nutanix stack of advanced technologies and requires no additional installation or integration, featuring full-stack management from a single, intuitive UI. The integrated architecture consolidates hypervisor and storage management functions into a single management plane.

Storage Path Optimization: Unlike conventional hypervisors that manage storage through traditional file systems, AHV does not leverage a traditional storage stack, with all disks passed to VMs as raw SCSI block devices.

This approach keeps the I/O path lightweight while allowing AOS to manage the distributed storage fabric through the CVM.

Version Compatibility: The relationship between AOS and AHV versions follows a structured compatibility model where each AOS release includes support for specific AHV versions. The upgrade process through Lifecycle Manager demonstrates the platform's integrated nature by handling both AOS and AHV upgrades simultaneously.

Conclusion

The live flow diagram clearly demonstrates that AOS and AHV function as a cohesive platform where the storage operating system and hypervisor are deployed together as complementary components of a single hyperconverged infrastructure solution. The Foundation installation process ensures both components are properly configured to work together from initial setup, eliminating compatibility issues that might arise from separate installations and providing the foundation for advanced features that require close coordination between hypervisor and storage layers.

High-Speed Networking for VMs: VMXNET3 Now Supports Up to 65 Gbps

2025-05-28T22:54:00.008+05:30

The VMXNET3 adapter is VMware's high-performance virtual network adapter, designed for optimized performance in vSphere environments. It is the default and recommended adapter for most modern workloads on ESXi, delivering high throughput, low latency, and support for advanced networking features.

With the release of vSphere ESXi 8.0 Update 2, VMXNET3 introduces new capabilities that significantly enhance virtual network performance.

What’s New in ESXi 8.0 Update 2 for VMXNET3?

Traditionally, VMXNET3 reports a default link speed of 10 Gbps to the guest operating system. However, the actual achievable throughput often exceeds this value—thanks to technologies such as multi-queue support, Receive Side Scaling (RSS), and Large Packet Offload.

Starting with ESXi 8.0 Update 2, this limitation can now be overridden, and VMXNET3 can be configured to support custom link speeds of up to 65 Gbps. This enhancement enables improved flexibility and throughput for high-performance workloads.

NSX Integration and Edge Node Optimization

In NSX environments, this update provides a strategic benefit: it allows Bare Metal Edge-level performance using VM-based Edge Nodes, eliminating the need for dedicated hardware in certain use cases. With vSphere 8.0.2 and above, virtual NICs configured with VMXNET3 can operate between 10 Gbps and 65 Gbps, offering a significant boost in data plane performance.

How to Configure VMXNET3 for 65 Gbps

You can configure the custom link speed using either the vSphere Client UI or by directly editing the VM configuration (.vmx) file.

Option 1: Configuration via vSphere Client

Navigate to the virtual machine in the vSphere Client.
Shut down the VM.
Right-click the VM and select Edit Settings.
Go to the VM Options tab.
Expand Advanced > Configuration Parameters, and click Edit Configuration.
Click Add Row and input the following:
- Name: ethernetX.linkspeed (Replace X with the NIC number, e.g., ethernet0)
- Value: Desired link speed in Mbps (between 10000 and 65000)
  - Example: ethernet0.linkspeed = 65000
Click OK to save the changes.

Option 2: Configuration via CLI (.vmx File Edit)

Shut down the VM.
SSH into the ESXi host where the VM resides.

Navigate to the VM's folder:

bash

cd /vmfs/volumes/<DATASTORE>/<VM_NAME>

Open the .vmx file in a text editor (e.g., vi):
```
bash

vi <VM_NAME>.vmx
```
Add the following line:
```
bash

ethernetX.linkspeed = "65000"
```
Replace X with the appropriate NIC number.
Save and close the file.
Power on the VM to apply the changes.

Important Notes

The linkspeed parameter is cosmetic—it changes what the guest OS perceives as the NIC speed but does not inherently guarantee line-rate throughput unless the VM and host are optimized.
Ensure that VMware Tools are installed and up to date for optimal driver compatibility.
Verify that the guest OS supports higher speeds and can take advantage of multi-queue NICs and large packet optimizations.

This configuration is particularly impactful for high-performance network functions virtualization (NFV), data-intensive workloads, and virtualized edge appliances in modern vSphere and NSX environments.

Mastering Kubernetes Ingress: The Gateway to Efficient Container Traffic Management

2025-05-23T23:24:00.007+05:30

In today's cloud-native landscape, efficiently managing traffic to your containerized applications is crucial for maintaining reliability, security, and performance. As organizations increasingly adopt Kubernetes for container orchestration, understanding how to properly implement and leverage Kubernetes Ingress becomes essential for DevOps professionals and platform engineers.

Kubernetes Ingress serves as the entry point for external HTTP and HTTPS traffic into your cluster, providing sophisticated routing capabilities that go beyond what basic Kubernetes Services can offer. It's the difference between having a simple doorway and a smart building management system that directs visitors exactly where they need to go.

As Kubernetes environments grow in complexity, with microservices architectures becoming the norm, the ability to intelligently route traffic, implement security policies, and maintain high availability becomes increasingly important. This is where Ingress truly shines.

In this article, we'll explore the fundamentals of Kubernetes Ingress, examine its key benefits, compare popular Ingress controllers, share implementation best practices, and look at real-world use cases that demonstrate its power in production environments. Whether you're new to Kubernetes or looking to optimize your existing infrastructure, this guide will provide valuable insights into mastering this critical component of modern container orchestration.

Understanding Kubernetes Ingress

At its core, Kubernetes Ingress is an API object that manages external access to services within a Kubernetes cluster, typically HTTP and HTTPS traffic. It acts as a sophisticated traffic director, routing incoming requests to the appropriate services based on rules you define.

How Ingress Fits into Kubernetes Architecture

In a typical Kubernetes environment, you have:

Pods: The smallest deployable units that contain your application containers
Services: Abstractions that define a logical set of pods and a policy to access them
Ingress: The layer that manages external HTTP/HTTPS routes to services

Without Ingress, exposing services to the outside world typically requires either using NodePort services, which expose services on specific ports across all nodes, or LoadBalancer services, which provision an external load balancer for each service. Both approaches have limitations - NodePort uses non-standard ports and LoadBalancer can become costly when you have many services to expose as its going expensive having multiple public IP's.

Ingress solves these challenges by providing a single entry point that can route to multiple services based on rules. This is more efficient, more flexible, and often more cost-effective.

Key Components of Kubernetes Ingress

Two essential components make up the Ingress system:

Ingress Resource: This is a Kubernetes API object that defines the routing rules. It's essentially a configuration file written in YAML that specifies how external HTTP/HTTPS traffic should be routed to services within the cluster.
Ingress Controller: This is the actual implementation that enforces the rules defined in the Ingress resource. It's a software component that interprets the Ingress rules and configures the underlying infrastructure (like NGINX, HAProxy, or cloud provider load balancers) to route traffic accordingly.

It's important to understand that simply creating an Ingress resource without an Ingress controller has no effect. The controller is what actually implements the routing logic defined in your Ingress resources.

A Simple Example

Here's a basic example of an Ingress resource:

This Ingress resource configures routing so that requests to example.com/app1 are directed to service1 and requests to example.com/app2 are directed to service2. The Ingress controller (in this case, NGINX ) implements these rules by configuring the underlying load balancer or proxy.

Understanding these fundamentals is crucial before diving into more advanced Ingress configurations and use cases.

Benefits of Implementing Kubernetes Ingress

Kubernetes Ingress offers numerous advantages that make it an essential component for organizations running containerized applications at scale. Let's explore the key benefits that make Ingress a powerful tool in your Kubernetes toolkit.

Single Entry Point for Multiple Services

One of the most significant advantages of Ingress is its ability to provide a unified entry point for multiple services. Instead of exposing each service individually with its own load balancer (which can become costly and complex to manage), Ingress allows you to:

Consolidate external access through a single IP address
Reduce infrastructure costs by minimizing the number of load balancers
Simplify DNS management with fewer public endpoints
Centralized traffic management policies

This consolidation is particularly valuable in cloud environments where each load balancer incurs additional costs and requires separate management.

Advanced Traffic Routing Capabilities

Ingress provides sophisticated routing mechanisms that go beyond basic IP/port-based routing:

Path-based routing: Direct traffic to different services based on URL paths (e.g., /api goes to the API service, /ui goes to the frontend service)
Host-based routing: Route traffic based on domain names, enabling multiple applications to share the same IP address
Header-based routing: Make routing decisions based on HTTP headers, enabling more complex traffic management scenarios
Regular expression matching: Use pattern matching for flexible routing rules

These capabilities enable complex microservices architectures where different components can be accessed through intuitive, human-readable URLs rather than remembering specific ports or IP addresses.

SSL/TLS Termination

Ingress simplifies the management of SSL/TLS certificates and encryption:

Centralized SSL/TLS termination at the Ingress level
Automatic certificate management with controllers like cert-manager
Ability to enforce HTTPS redirection
Support for multiple certificates for different hosts

By handling encryption at the Ingress layer, you can offload this responsibility from your application containers, simplifying their configuration and reducing resource consumption.

Name-based Virtual Hosting

Ingress enables efficient name-based virtual hosting, allowing you to:

Host multiple websites or applications on a single infrastructure
Separate traffic based on domain names (e.g., app1.example.com, app2.example.com)

WAF Integration: For applications handling sensitive data, consider integrating a Web Application Firewall (WAF) with your Ingress controller to protect against common web vulnerabilities.

Performance Optimization

Optimize your Ingress configuration for maximum performance:

Resource Allocation: Properly size your Ingress controller deployment based on expected traffic patterns. Monitor resource usage and adjust accordingly.
Connection Handling: Configure appropriate timeouts, keepalive settings, and connection limits to optimize resource usage.
Caching: Implement caching strategies at the Ingress level for static content to reduce backend load and improve response times.
HTTP/2 and HTTP/3: Enable modern HTTP protocols to improve performance, especially for clients with high-latency connections.
Compression: Configure compression for appropriate content types to reduce bandwidth usage and improve load times.

Scalability Approaches

Design your Ingress architecture for scalability:

Horizontal Scaling: Deploy Ingress controllers as a Deployment or DaemonSet with multiple replicas to handle increased load.
Affinity Configuration: Use pod anti-affinity to ensure Ingress controller pods are distributed across nodes for high availability.
Load Distribution: In large clusters, consider using multiple Ingress controllers for different services or namespaces to distribute load and provide isolation.
Autoscaling: Implement Horizontal Pod Autoscaling (HPA) for your Ingress controllers based on CPU, memory, or custom metrics like request rate.
Regional Distribution: For global applications, deploy Ingress controllers in multiple regions with DNS-based global load balancing.

Monitoring and Troubleshooting

Establish robust monitoring and troubleshooting practices:

Metrics Collection: Configure your Ingress controller to expose Prometheus metrics and set up dashboards to visualize traffic patterns, error rates, and latency.
Logging: Implement structured logging with appropriate verbosity levels. Consider using a centralized logging solution to aggregate logs from all Ingress controllers.
Health Checks: Configure comprehensive health checks for both the Ingress controller itself and the backend services.
Tracing: Implement distributed tracing with tools like Jaeger or Zipkin to understand request flow through your system.
Alerting: Set up alerts for critical conditions such as high error rates, increased latency, or certificate expiration.

Configuration Management

Manage your Ingress configurations effectively:

GitOps Approach: Store Ingress configurations in a Git repository and use tools like ArgoCD or Flux to ensure deployed configurations match the desired state.
Templating: Use Helm charts or Kustomize to template your Ingress resources, making them easier to manage across environments.
Annotations Documentation: Maintain clear documentation of all annotations used in your Ingress resources, as these can vary between controllers.
Progressive Deployment: Test Ingress changes in lower environments before applying them to production.

By following these best practices, you can create a robust, secure, and scalable Ingress implementation that effectively manages traffic to your Kubernetes services while minimizing operational overhead.

Real-world Use Cases

Kubernetes Ingress has proven its value across various industries and deployment scenarios. Let's explore some real-world use cases that demonstrate how organizations leverage Ingress to solve complex traffic management challenges.

Multi-tenant Environments

Many SaaS providers use Kubernetes to host multiple customer instances on shared infrastructure. Ingress plays a crucial role in these environments:

Domain-based Tenant Isolation: Each tenant gets their own subdomain (e.g., customer1.example.com, customer2.example.com) with Ingress routing traffic to the appropriate tenant's services.
Authentication Boundaries: Ingress controllers can enforce tenant-specific authentication, ensuring users can only access their designated environment.
Resource Isolation: Combined with namespace separation, Ingress helps maintain clear boundaries between tenant resources while sharing the underlying infrastructure.

A large enterprise software provider successfully migrated from a traditional VM-based deployment to a Kubernetes platform, using Ingress to route traffic to over 500 customer instances. This transition reduced their infrastructure costs by 40% while improving deployment speed and reliability.

Microservices Architectures

Organizations with complex microservices architectures rely heavily on Ingress:

API Gateway Pattern: Ingress serves as an API gateway, routing external requests to the appropriate internal microservices based on URL paths.
Backend for Frontend (BFF): Different client applications (web, mobile, third-party) can be routed to specialized backend services optimized for their needs.
Versioned APIs: Ingress can route traffic to different versions of services, enabling smooth API evolution without breaking existing clients.

A financial technology company uses this approach to manage its payment processing platform, which consists of over 30 microservices. Their Ingress configuration routes traffic based on both path and client type, ensuring optimal performance for different integration patterns.

Blue-Green Deployments

Ingress facilitates sophisticated deployment strategies:

Zero-downtime Deployments: By maintaining both "blue" (current) and "green" (new) versions of an application, Ingress can instantly switch traffic between them.
Instant Rollback: If issues are detected in a new deployment, traffic can be immediately redirected back to the previous version.
Environment Validation: QA teams can validate the "green" environment before it receives production traffic.

An e-commerce platform uses this approach during its high-traffic holiday season, successfully deploying multiple updates per day without any customer-facing downtime, resulting in a 15% increase in conversion rates due to rapidly deployed optimizations.

Canary Releases

Ingress controllers enable sophisticated canary deployment strategies:

Percentage-based Traffic Splitting: Gradually increase traffic to a new version, starting with a small percentage (e.g., 5%) and increasing as confidence grows.
User-based Canaries: Direct specific user segments (e.g., internal users, beta testers) to the new version while keeping most users on the stable version.
Feature Flags: Combined with application-level feature flags, Ingress can help implement complex progressive delivery strategies.

A streaming media service uses canary deployments via their Ingress controller to test new recommendation algorithms with 2% of their user base before full rollout, reducing the risk of negative user experience while enabling rapid innovation.

Global Application Delivery

Organizations with a global presence use Ingress as part of their worldwide application delivery strategy:

Regional Ingress Controllers: Deploy Ingress controllers in multiple geographic regions, each serving users in that region.
Global DNS Load Balancing: Use DNS with geo-routing to direct users to the nearest regional Ingress.
Consistent Configuration: Maintain consistent Ingress configurations across regions while allowing for regional customizations where needed.

A global SaaS provider implemented this architecture to reduce average response times by 65% for their international customers while maintaining a single, consistent deployment pipeline.

These real-world examples demonstrate the versatility and power of Kubernetes Ingress in solving complex traffic management challenges across different industries and use cases. By understanding these patterns, you can apply similar strategies to your own Kubernetes environments.

As Kubernetes continues to evolve, so does the landscape of ingress and traffic management. Understanding emerging trends will help you make forward-looking decisions about your infrastructure. Here are the key developments shaping the future of Kubernetes Ingress.

Gateway API as the Evolution of Ingress

The most significant trend in Kubernetes traffic management is the emergence of the Gateway API, which is designed to address the limitations of the current Ingress resource.

Enhanced Expressiveness: Gateway API provides more sophisticated configuration options than traditional Ingress, allowing for complex routing scenarios that previously required custom annotations.
Improved Role-oriented Design: The API is structured around distinct roles (infrastructure providers, cluster operators, application developers), making it easier to manage responsibilities in large organizations.
Standardized Configuration: Gateway API aims to reduce the reliance on controller-specific annotations, creating a more consistent experience across different implementations.
Native Support for TCP/UDP: Unlike traditional Ingress which focuses primarily on HTTP/HTTPS, the Gateway API natively supports TCP and UDP protocols.

Many Ingress controller providers are already implementing Gateway API support alongside traditional Ingress resources, allowing for a gradual migration path. Organizations planning long-term Kubernetes strategies should begin familiarizing themselves with Gateway API concepts.

Integration with Service Mesh

The line between Ingress controllers and service mesh technologies continues to blur:

Unified Traffic Management: Solutions that combine north-south (external) traffic handled by Ingress with east-west (internal) traffic managed by service mesh are becoming more common.
Consistent Security Policies: Integrated approaches allow security policies to be applied consistently across both external and internal traffic.
End-to-end Observability: Combined solutions provide visibility into the entire request path, from external entry to internal service-to-service communication.
Simplified Operational Model: Managing a single system rather than separate Ingress and service mesh components reduces operational complexity.

Projects like Istio and Linkerd are leading this integration trend, offering unified approaches to traffic management that span both ingress and mesh capabilities.

Multi-cluster Ingress Solutions

As organizations adopt multi-cluster Kubernetes strategies for reasons including geographic distribution, failure isolation, and regulatory compliance, multi-cluster ingress solutions are gaining importance:

Centralized Management: Tools that allow managing Ingress across multiple clusters from a single control plane.
Global Load Balancing: Intelligent traffic distribution across clusters based on factors like proximity, cluster health, and capacity.
Consistent Policy Enforcement: Applying consistent security and routing policies across all clusters regardless of their location or provider.

Advanced Threat Protection: Integration with security tools that provide protection against sophisticated attacks, including API-specific threats.
Automated Certificate Management: More sophisticated and reliable automation around certificate issuance, renewal, and revocation.
Identity-aware Proxying: Deeper integration with identity providers to make access decisions based on user identity rather than network location.

These security enhancements are particularly important as organizations expose more critical workloads through Kubernetes.

AI-powered Traffic Management

Emerging solutions are beginning to incorporate artificial intelligence for more intelligent traffic management:

Anomaly Detection: Identifying unusual traffic patterns that might indicate security threats or application issues.
Predictive Scaling: Anticipating traffic spikes and proactively scaling Ingress resources before traditional metrics would trigger scaling.
Intelligent Routing: Dynamically adjusting routing rules based on real-time performance data to optimize user experience.
Automated Troubleshooting: Using AI to analyze traffic patterns and identify the root cause of issues faster than manual investigation.

While still in early stages, these AI-powered capabilities represent the next frontier in Kubernetes traffic management.

By staying informed about these trends and planning accordingly, organizations can ensure their Kubernetes ingress strategy remains effective and future-proof as the technology landscape continues to evolve.

Quick view on NSX Multi-Tenancy

2023-11-21T12:42:00.032+05:30

NSX-T brings an evaluation into SDN space whether it's networking, security or even monitoring the environment.

During its long journey starting from acquiring this product from Nicira Network by VMware to date, we have seen several enhancements evolving into this product.

From NSX-V to NSX-T and now rebranded to NSX starting from version 4. x this product is all set on the customer expectation whether it's a startup or a multi-billion Fortune 500 organization.

In this article, we will discuss one of NSX new offerings in NSX ver 4.1 which is NSX Project or multi-site tenancy.

Before starting into this let's draft a hypothetical or fictitious scenario...

In an organization called Virtualvmx, there were 3 tenancies:

Alpha
Beta
Gama

All the above 3 tenants have some compliance guidelines for their organization where one tenant should not expose its networking component inside NSX with other tenants like Layer 2 networking which includes segment, security policies, T1 routers and so on.

Before NSX 4.1..x we had no such capabilities as all tendencies were exposed to each other with their networking components like segments, T1, DFW policies, segment profiles, etc.

Starting from NSX 4.1.x we can accomplish this requirement with the offering of NSX Project.

Using NSX Project one can isolate all its securing networking components from one tenant to another in a single NSX Deployment.

In NSX 4.1.x we can have multi-tenancy created for all 3 tenancies under NSX Project to accomplish the isolation of networking & security for individual tenancy.

Under multi-tenancy, each tenant can isolate their L2 networking with other tenants. However, L3 networking which includes T0 routers (Edge nodes) going to be shared with other tenants or could be dedicated to individual tenancy as per requirement.

Once you start creating projects inside NSX for individual tenancy, at that stage there will be 2 views on NSX which are:

Default view.
Project view.

Default view:

This is the section that is governed by NSX Enterprise administrator or other security role which is generally not assigned to individual tenancy.

In this view, the Enterprise administrator has the ability to modify T0 routers, Edge nodes, transport zones, and so on. In a nutshell, Default space is that space that is not assigned to any project.

The below picture shows the view of the default section.

In this view, the Enterprise administrator has the full privilege to add/remove or modify any L2 or L3 components inside NSX deployment.

Default View in NSX Manager

Now, From the Default view you can create multiple projects as mentioned below:

To create a new project. Go to > Manage Projects.

Also, you have to assign RBAC policies to the project which is associated with the project.

Here you could associate the shared T0 gateway/ Edge Cluster used by other projects or you can decide dedicated T0 for individual projects.

In this scenario, we have created 2 projects. Alpha & Beta. Both the projects are assigned to individual users through RBAC policy and assigned with a Project Admin role.

Project View

Now we will try to log in with the newly created user " Beta" which we have assigned to Beta users giving project admin role.

Here when we log in on NSX using Beta project credentials, only the project-specific view is displayed. as shown in the below screenshot. Observe that the "System" tab is not visible to the Project Admin as that functionality of managing entities under "System" is privileged to Enterprise admin only.

At present in the current version, NSX Project only supports 1 edge cluster configured on the "default" overlay-transport zone. Custom transport zone is currently not supported.

Having said that, compute and edge transport nodes going to be configured with the transport node name "nsx-overlay-transportzone" which is the default in NSX.

The above described is just a 30,000-foot view of the NSX Project. In a nutshell, this can be opted by those who use single NSX deployment being shared with multiple tenancies where they want to isolate networking & security elements from one tenant to another.
