Managed and Semi-Managed Web Services
Web hosting has never been more affordable—or more complicated. Rich media, social networking, sophisticated eCommerce platforms are all making the Internet experience incredibly dynamic and profitable. Still, security threats are greater: last year alone, the number of viruses, worms and trojans in circulation topped the one million mark—that’s in addition to ever-growing levels of spam, phishing scams and malware. The Open Security Foundation added more than 11,000 new vulnerabilities to its database in 2008. Critical OS patches and software updates never seem to end. Data loss? That’s on the rise as well, due primarily to hardware or system malfunctions or human error, but also corrupted software, power outages and malicious programs. And messaging, always critically important to organizations, carries a huge and mounting cost due to email downtime resulting from system failures.
Managed hosting services as a concept promises a coordinated, comprehensive solution to address many of the time-consuming tasks facing small- and medium-sized businesses (SMBs) looking for a web presence—particularly those without the necessary expertise or in-house resources to maintain and optimize their own web servers. Semi-managed plans offer a less expensive option compared to traditional, fully-managed services. Yet in terms of scalability, flexibility and the ability to deploy services quickly, both approaches present a viable alternative for server management in meeting today’s web hosting challenges.
Overview of Managed/Semi-Managed Hosting
Why Use Managed/Semi-Managed Hosting?
The cost and complexity of web hosting keeps rising: domain management, expanding server loads, ongoing software updates, and security monitoring, along with increasing demands for messaging encryption, archiving and reliability. In addition, site owners must address the critical nature of backups and data protection/restoration in the event of power outages and other disruptions, natural or man-made.
In short, it’s becoming more complex and more confusing than ever for SMBs to efficiently maintain a stable, secure web presence. The biggest challenges site owners face today include:
- Increased messaging is more difficult to manage: maintaining email functionality, data retention, and protection against spam, phishing, viruses, worms, spyware and other threats.
- DNS services are increasingly complex: DNS records configuration and management, administering multiple domains, vulnerabilities from DNS-based buffer overflow attacks.
- Server and software patch management is time consuming: consistent, regular OS patching to minimize exposure/vulnerabilities, controlling and managing software and security updates.
- Storage, data backup and data recovery requirements are growing: continuous data protection, incremental backup, off-site data management, and database and application backup and recovery (SQL, Exchange, Sharepoint, CRM).
- Network and security management will continue to command more attention—and resources: firewall configuration, scanning for malware, check sum changes in software on the server, bandwidth and port monitoring to assess ongoing risks.
- Disaster recovery and business continuity are essential, but rarely planned out thoroughly in advance: protecting against loss of sensitive data and network connectivity, downtime, reboots, service failures, power outages and other disruptions.
Server Hosting Defined
To understand further the merits of managed—fully or semi—managed services as an option for SMBs, it’s important first to understand more closely how they compare to other available types of hosting (beyond shared hosting).
Co-Located Hosting involves the purchase of a server from a hardware vendor; the server is then delivered to a web host and connected to the host’s network and redundant power systems. The host is responsible for the network, while site owners are responsible for server support, maintenance and software updates. The biggest issue with co-location? If hardware fails, the customer must ship new hardware to the data center—potential long periods of downtime outside of the SLA.
Unmanaged Dedicated Hosting is similar to co-location except the host owns the hardware, while it is the customer’s responsibility to manage and administer its operation. Support contracts may be available, but it generally falls to the customer, not the host, to install and update server software and OS patches, data backups, monitor security, manage email, etc. In this scenario, the web host is responsible for failed/defective hardware, network, and power systems.
Managed Services involves leasing one or more servers from a host, which then proactively provides support and maintenance on that equipment, usually backed by quality guarantees. Additional services then provided by experienced system administrators on staff typically include server uptime monitoring, OS patching, operating system restores, security monitoring, and more.
Market Trends
Tier1 Research:
“Managed Hosting: Market Overview Spring 2008”
(April 15, 2008)
“…the managed hosting sector has experienced tremendous growth in the past 12 months—in excess of 30%—driven by several trends. These trends include virtualization, business continuity services and security technologies, driven both by enterprise demand and regulatory compliance. Despite the dipping economy in the US, there has been increased managed hosting adoption by SMBs and mid-tier enterprises in both the US and Europe.” Read the rest of this entry »
