Top 5 Books to Learn Docker for Beginners in 2027 - Best of Lot

2026-09-21T06:37:37.229-07:00

Hello guys, if you are a developer or software engineer then you might have heard about Docker and containers. Being an author of a Java and Programming blog, I daily receive a lot of questions about Docker like what is Docker? what is Docker compose, which Docker commands should I learn, what is Docker Hub, How can I migrate my application to Docker and how can I deploy Docker container on AWS, Azure, and GCP. These are also some of the common doubts of programmers across the world. Let's start with What is Docker and why a Programmer should learn Docker? Simply speaking, Docker programming language makes project management and deployment seem easy.

Like most software technologies out there, Docker provides a great level of abstraction which makes it easy to bundle an application and its dependency, which in turn makes it easy to deploy the application on cloud.

Docker also aims to solve the classic problem of application working on one machine but not working on others. It does that by abstracting all things including OS which is needed by the application to run.

Docker was first launched by Solomon Hykes in 2013. It is the most popular DevOps tool, and great for continuous deployment and testing. Docker containers make sure there is consistency with multiple environments, developments, and release cycles, helping to standardize your environment.

If you want to learn Docker then you have come to the right place. In the past, I have shared best Docker and Kubernetes course as well as free courses to learn Docker, and today I'll share the top five books anyone can learn Docker from scratch. The list contains Docker books for both beginners and experienced programmers, who want to learn Docker in-depth.

And, if you are in rush and just want to start with online courses first then you can start with Docker and Kubernetes: The Complete Guide course on Udemy, its one of the better courses to learn Docker and Kubernetes online and suitable for both beginners and experienced developers.

5 Best Docker Books for Beginners and Experienced in 2027

Without wasting any more of your time, here is my list of 5 best books to learn Docker for beginner's perspective. Though, this list is not just for beginners but also for an experienced developer who wants to learn Docker in-depth.

I have also included books like Docker Deep Dive which is really great to level up your Docker Skills and become the developer every company wants to hire.

1. Docker Deep Dive: Zero to Docker in a single book by Nigel Poulton

As the name entails, this book offers one a chance to become the grandmaster of Docker. It is also touted as the best Docker book online. It offers lessons on the deeper and advanced parts of Docker and tackles setups like AS,(automated server).

This book is useful for both beginners and experts. If you want to learn Docker from scratch, you can use this book and if you want to learn Docker in-depth then also this is a useful book. The best part of this book is that it's updated regularly which is very important to learn something like Docker which is constantly updated.

The book provides an in-depth explanation of Docker architecture and deep dive into concepts like Docker image and containers. It also covers Networking, Security, and Volumes.

This book also covers the Docker Certified Associate (DCA) certification, which means you can also use this book if you are preparing for Docker certification.

The book is written by Docker Captain and leading educator in the container ecosystem Nigel Poulton and if you like you can also combine this book with the Udemy course Docker for the Absolute Beginner - Hands On - DevOps to learn better. It has got a lot of hands-on coding exercises to learn Docker in a active and fun way.

2. Docker a Project Based Learning

Have you tried to learn Docker on your own, but lack the structure you need to really improve your skills?

Are you tired of picking up bits and pieces of information that you can’t just seem to put together?

Do you learn best by doing?

If so, you’re going to love this book.

One of the biggest complaints from students is that most of the books they’ve read in the past simply provide information without any context and without any idea of how to put that information to use!

This book turns that old, frustrating, and outdated way of learning on its head.

It’s project-based, which means instead of learning bits and pieces of information, you’ll learn the exact Docker commands that you can use in real-world situations. You get the chance to immediately put what you learn to use so that you fully understand and remember it.

The table of contents covers Introduction to Docker, Installing Docker, Getting Started with Docker, Working with Docker images and repositories, Testing with Docker, Building services with Docker, Orchestration with Docker Compose, Docker Swarm and Consul, Using the Docker API, and Extending Docker.

Btw, If you like online courses then you can also combine this book with the Docker and Kubernetes: The Complete Guide course by Stephen Grider on Udemy. It's one of the best and up-to-date courses to learn both Docker and Kubernetes and Stephen is well known for making complex things simpler.

3. Docker in Action 2nd Edition

Just like the name suggests, Docker in Action is a practical book with live examples and working exercises. It was written by Jeff Nicoloff, a Docker expert and the book teaches the following:

Running programs securely and packaging containers for deployment with how to manage shared resources. Users will also learn to create and to deploy projects in Docker, managing applications hosted in Docker containers, and working with Docker images.

There are also lesson on how to use DuckerHub for distribution and techniques for using Docker on systems ranging from dev-and-test machines to full-scale cloud deployments. Package applications in containers, including techniques for testing and distributing applications.

I also recommend you to combine this book with a hands-on course like Docker for the Absolute Beginners - hands-on DevOps on Udemy. It's a great course with a lot of exercises to learn essential Docker commands. You will also learn how to compose files with exercise and understand Docker swarm in detail.

4. Learning Docker Second Edition

If project deployment is all you are about as a developer then this particular book on Docker might just be for you. Although Learning Docker requires a little knowledge of web programming, no knowledge of Docker or container is required.

The authors Pethuru Raj, Vinod Singh, and Jeeva S. Chelladhurai have also written other amazing programming books and ensures that any beginner developer can learn Docker by reading this book.

With this book, you will learn how to build a Docker image using Dockerfiles, push and publish images on Docker Hub, a maven like a repository, run your own private Docker Hub and upload images onto it, compose, use, and publish the Docker containers, leverage the features of Docker to deploy your existing applications and explore real-world examples of securing and managing Docker containers.

If you want, you can also combine this book with the Docker in a Weekend: 40 Practical Demos for DevOps Learners course from Udemy for active and fun learning.

5. Docker: Up and Running 2nd Edition

The book was written by Karl Matthias and Sean P. Kane and is all about the advanced and practical aspects of Docker. If you are a newbie then this is not the right fit for you.

It tackles Docker concepts like how to keep internal dependencies, package applications, and maintain consistent project environment during local testing and deployment.

It also teaches Docker on several levels such that it makes dependency management very simple for deploying workflow for applications.

Like with the previous books, it covers how to excel working with Docker images, containers, and command-line tools with the use of practical techniques to deploy and test Docker-based Linux containers in production.

If you are done with all the basics and you still want more, then checking out Docker Mastery: with Kubernetes and Swarm course still have some more advanced concepts. The courses are taught in very simple English and by a Docker captain himself, which makes it a nice companion of this book, particularly for people who wants to learn Docker in-depth.

That's all about the best books to learn Docker for beginners in 2027. As I have said before, Docker is an essential skill for every programmer as more and more companies are switching to container-based deployment. If you can, I highly recommend you to learn Kubernetes as well because Docker and Kubernetes go along nicely as nobody deploys containers manually nowadays they use Kubernetes to deploy containers at scale.

P. S. - If you prefer online courses over books or just want to do some active learning then I also recommend you check out Docker and Kubernetes: The Complete Guide course by Stephen Grier on Udemy. It's one of the best and up-to-date courses to learn both Docker and Kubernetes and Stephen is well known for making complex things simpler.

Why AlgoMonster Works Better Than Random LeetCode Grinding

2026-09-21T06:26:01.993-07:00

Hello guys, cracking the coding interview is not easy anymore, even for experienced developers because software engineering interview has completely changed now.

Gone are the days when we can just remember ArrayList vs LinkedList and ArrayList vs Vector and get a job, now there are multiple rounds, with take home test, CoderPad or HackerRank test, live coding and System Design.

If you still want to be employable then you need to adapt and learn things which matters like Coding Patterns and System Design.

When I first started preparing seriously for coding interviews at top tech companies like Meta, Google, and Amazon, I did what most people do — I jumped straight into LeetCode, picked random problems, and hoped for the best. But the results were mixed.

I would often solve a problem only to forget the approach a week later. That’s when I discovered AlgoMonster — and my approach to Data Structures and Algorithms changed for good.

AlgoMonster isn’t just another collection of problems.

It’s a pattern-based system for solving coding questions. It teaches you to first identify the pattern before jumping into code — whether it’s sliding window, binary search, two pointers, or BFS/DFS.

Each pattern has well-organized theory, real examples from tech interviews, and problems arranged by difficulty level.

They even have pattern-specific ladders for Meta, Google, and Amazon — something I haven’t seen anywhere else, not even on platforms like Exponent, ByteByteGo, Educative, or DesignGuru.

AlgoMonster Practice Tool — Solve Coding Problem by Identify Patterns

One of my favorite parts is their Monster 50 and Blind 75 lists. Instead of just practicing blindly, AlgoMonster guides you to approach each problem with a strategy-first mindset:

Identify the pattern
Sketch the solution
Implement the code
Analyze the time and space complexity

This step-by-step process ingrains the right habits. Over time, I stopped panicking when I saw a tough question.

I started recognizing familiar patterns, and that boosted both my accuracy and confidence in mock interviews. It was like seeing the matrix.

Their coding platform is also very top notch similar to what you will find in Exponent, Educative, and HackerRank.

Here is how AlgoMonster’s Coding Interview Practice tool look like

You can try their practice tool here, its complete free, just click on the Practice Tab.

How much AlgoMonster cost?

Talking about cost and fees, another huge advantage of AlgoMonster is? Price.

AlgoMonster is one of the most affordable platforms available today. Their lifetime plan costs only a few hundred dollars, and compared to the thousands charged by InterviewKickstart or other bootcamps, it’s an absolute steal.

You get:

Lifetime access to curated content
Regularly updated problems
Guided solutions with analysis
Strategy built for FAANG and Tier-1 companies

To top it off, the Reddit community has tons of positive reviews and real success stories. People talk about how they went from struggling with brute-force thinking to identifying optimal solutions thanks to the structure AlgoMonster provides.

If you’re serious about cracking coding interviews and want to save both time and money, I genuinely believe AlgoMonster is the best way to go.

Is it really worth to get a AlgoMonster PRO lifetime membership for $459 (U.P. $918) now?

For more practice, you can even combine AlgoMonster with LeetCode to cement your understanding. Use AlgoMonster to learn the patterns, and LeetCode to reinforce them through volume. That combo worked wonders for me.

You can also combine AlgoMonster with Exponent which provides mock interviews.

By creating a free Exponent account you can do interview with peers. They give 5 interviews to everybody and credit also replenish over time when you receive positive feedback.

You can check Exponent’s mock interview tool here.

Final Thoughts

That’s all about why Algomonster is the best platform for learning and practicing Data Structures and Algorithms for coding interviews. Unlike traditional platforms where you’re overwhelmed with problem sets and little guidance, AlgoMonster acts like a mentor — helping you build strong fundamentals through patterns.

If I had to choose between AlgoMonster and Exponent, ByteByteGo, Educative, or DesignGuru. — especially for coding problems — I’d go with AlgoMonster without hesitation.

Another great thing about them is that they are offering 50% discount now, and the value it provides, AlgoMonster is definitely worth it. Here is the link to join Algomoster now for a 50% discount

Other System Design and Coding Interview and Resources you may like

All the best for your Coding Interviews, if you have any doubts or questions, feel free to ask in the comments.

P. S. — If you just want to do one thing at this moment, go join Algomonster and start learning DSA Concepts and practice coding interviews you will thank me later. It’s one of the most comprehensive resource for coding interview now.

In this article, I will share some of the best Web Development courses you can take to learn online by yourself. Suppose you are a regular reader of this blog. In that case, you might know that earlier, I have shared about The Complete Web Developer RoadMap, which outlines how you can become a Modern Web Developer everybody wants to hire. In that post, I have explained how you can learn everything about Programming and Web Development from scratch and with no coding experience.

I have also shared my three-point formula to learn a new technology or framework, which I have used to determine many technologies in the past like Git, Data Structure and Algorithms, Hibernate, Kotlin, Docker, and Android to upgrade my technical skills.

You can also use the same technique to become a Web developer this year. You should generally start with an excellent online course, which will help you understand the most critical part and gain some hands-on experience, like how to set up your development environment and build some simple applications.

Once you understand fundamentals, you can read a book to get more comprehensive coverage of all the concepts covered in the online course and something that has not been covered. After completing the book and online course, you should develop a real-world application to test your knowledge and fill gaps in your learning.

I have recently shared a lot about excellent online courses to learn new technologies, frameworks, and libraries. Like in the last article, I have listed down some of the free Java courses. Today I'll list down the top 5 Web development courses from Udemy which I have bought and joined myself.

Talking about web development, things have changed a lot in the last 5 to 10 years. Gone are the days when knowing just HTML, CSS, and JavaScript was enough.

They are still essential but not enough; you also need to learn modern web development frameworks like React, Angular, Bootstrap, etc., to develop modern web applications.

These frameworks have made web development more structured and organized. They also allow you to build from just a single-page web application to full-fledged, real-world web applications like Facebook, Airbnb, or Uber.

If you are interested in learning cutting-edge technology like React JS, Spring Web-Flux, Redux, Bootstrap, then these web development courses are good to start with. You will get exposure to many client sides and server-side technology by going through these courses.

Top 5 Udemy Courses to become a Frontend Developer in 2027 - Best of Lot

2026-09-21T06:16:17.821-07:00

Front-end development is a critical skill for web developers as there is a lot of demand for programmers with excellent front-end development skills. If you've never experienced client-side web development, learning the plethora of frontend technologies can be difficult. Still, with proper guidance and choosing suitable courses, you can achieve your target. The one thing which I want to tell you is that a good knowledge of HTML, CSS, and JavaScript is a must for any frontend developer. Even though we live in the era of frameworks and libraries, knowledge of these fundamental technologies cannot be undermined.

I know many web developers who directly start with frontend frameworks like Angular, Bootstrap, React, and Vue without spending much time learning the underlying pillars like HTML, CSS, and JavaScript, which means they struggle to debug their applications and are stuck whenever their applications run slow, UI freezes or elements not appearing as they want.

While creating this list of frontend development online courses, I have to keep in mind that the classes I include teach you the latest and most significant frontend framework and fundamental technologies like HTML 5 and CSS 3.

Most of the courses in this list walk you through the basics of client-side web development by showing you how to build web pages with HTML, Cascading Style Sheets, JavaScript, and jQuery and then showing you what you can do with React, Angular, or Vue.js.

I have not included any course on full-stack development or Node.js, but if you want to learn, you can always look back to my earlier list for the best free Node.JS courses and full-stack development courses for beginners.

5 Best Udemy Courses to Learn Frontend Web Development in 2027

Without wasting your time, here is my list of some of the best online training courses and certifications to learn frontend web development for beginners. It includes classes and certifications from Udemy, Coursera, and Pluralsight, sequences from reputed universities worldwide, and expert trainers who have real-world experience building professional websites and mission-critical web applications.

1. The Complete Front-End Web Development Course!

This is one of the best courses to learn Front-end web development. It covers some of the most helpful programming languages ad technologies you will need as a frontend web developer, like HTML, CSS, JavaScript, jQuery, and Bootstrap!

Created by Joseph Delgadillo and Nick Germaine, this course is also very hands-on, and you will start by creating a simple web page using HTML to write a chrome extension using JavaScript.

Talking about social proof, more than 119,530 students have already benefitted from this course, and it also has, on average, 4.3 ratings from close to 3,468 participants, which is phenomenal.

2. Programming Foundations with JavaScript, HTML, and CSS [Coursera]

This is an excellent free course from Coursera to learn Front-end development and programming fundamentals using JavaScript, HTML, and CSS.

Offered by Duke University, this free course will teach you how to write JavaScript programs using functions, for loops, and conditional statements; How to use HTML to construct a web page with paragraphs, divs, images, links, and lists; Add styles to a web page with CSS Ids and classes; and Make a web page interactive with JavaScript commands like alert, onClick, onChange

By the end of the course, you will also create a web page where others can upload their images and apply the image filters that you make. Like many other Coursera courses, this one is also free-to-audit. Still, you need to pay if you need a certificate and access to all quizzes, and programming assignments, which by all means you should do if you appreciate Coursera and value certificates.

I highly recommend this front-end course to beginners and people with no coding/programming experience.

And, if you find Coursera courses and helpful specialization, you should also join Coursera Plus, a subscription plan from Coursera that provides you unlimited access to their most popular courses, specialization, professional certificate, and guided projects. It costs around $399/year, but it's completely worth your money as you get unlimited certificates.

3. The Web Developer Bootcamp [Udemy Best Course]

This is one of my favorite courses to learn about Web development, and I highly recommend it to frontend developers. It is the only course you need to know about web development - HTML, CSS, JavaScript, Node, etc. It does not just focus on frontend development but also on the backend and other aspects of web development.

Talking about social proof, 434,580 students have already benefitted from this course, and it has, on average, 4.6 ratings from 126,888 participants, which is phenomenal.

I am also a big fan of instructor Colt Steele, whose bootcamp style makes learning easier. Having been a bootcamp teacher, he knows what he is teaching, and he does it in no non-sense manner. If you could just buy one course to learn frontend development, but this one.

4. Front End Web Development: Get Started By Joe Eames

One of the critical challenges of frontend development is that it involves many technologies, and they also keep changing, and that's why a strong foundation of the underlying technology is a must.

For the beginner, starting to learn frontend development can be daunting, and that's where this course helps. It will teach you the basics of all aspects of front-end web development and how to hone and keep your skills up to date.

The instructor Shawn Wildermuth is also very detailed and shows you step-by-step how to use client-side web development techniques to create immersive websites.

5. Frontend Web Development with React [Coursera Best Course]

This is another excellent course to learn about Web development, particularly frontend web development on Coursera. Unlike previous classes, which focus on HTML, CSS, and JavaScript, this course focuses on React library, a popular JavaScript library for front-end application development, vital for a modern web developer.

This course also uses JavaScript ES6 to develop React applications, which will help you understand new JavaScript features from ES6.

The course also touches on various aspects of Redux and uses it to develop React-Redux-powered applications. You will also learn how to use Fetch for client-server communication and REST API on the server-side.

The course also provides a quick tour through React animation support and testing rounds off the course. The Hong Kong University of Science and Technology offered this course and delivered it by Jogesh K. Muppala, Associate Professor from the Department of Computer Science and Engineering.

Like other Coursera courses, this is also free to learn, but you need to pay for a certificate and access to various assignments and quizzes. If you don't connect with the instructor and need a choice, you can also check out Max's React - The Complete Guide course on Udemy, my personal favorite. It covers both Hooks and Redux, along with React Router.

That's all about some of the best online training courses and certifications to become a frontend developer. If you have any other excellent lessons about front-end web development, feel free to share.

As I said, learning frameworks like Angular, React, Vue.js, and Bootstrap is important. Still, learning fundamentals like HTML, CSS, and JavaScript are even more critical, and you should prioritize that before jumping with the framework.

That will also help in the long run with debugging, troubleshooting, and dealing with performance issues with real-world web applications.

In today's world of Agile and DevOps, Jenkins has become an indispensable tool for both Java programmers and DevOps engineers. Jenkins allows you to set up continuous integration (CI) and continuous deployment (CD) pipeline, which reduces risk on Software development and delivery. This means hassle-free development and deployment. It also means quicker feedback because as soon as a commit has been made into a source control system like Git, Jenkins can start building artifacts and running unit tests. You will instantly receive an email if the build fails due to an issue or a unit test doesn't pass. This quick feedback loop ensures that your codebase remains error-free.

It is also one of the most exciting technologies of the last decade regarding its disruption to software development and operational practices. Many people believe that Jenkins started the DevOps revolution by offering Continuous Integration and Continuous Deployment.

The Jenkins Continuous Integration solution has become a standby in organizations of all sizes that want to increase productivity and streamline software development in the era of Agile. It has extensive community support has extended the core functionality of Jenkins by developing thousands of useful plugins.F

An ecosystem of more than 1,100 plugins has emerged, enabling customers to add all sorts of functionality and integrate Jenkins with everything from Active Directory to GitHub to Tomcat.

Jenkins is also becoming a must-have tool for DevOps. It allows companies to build very sophisticated pipelines quickly, thus significantly reducing the risk within the software development lifecycle.

Tons of companies have already been using Jenkins to implement a continuous integration pipeline. Today you have access to that same technology right on your desktop.

6 Best Udemy Courses to Learn Jenkins and CI/CD in 2027

Here is my list of some of the best Jenkins courses for Java Programmers and DevOps engineers without any further ado. Both junior and senior programmers can benefit from these courses. I have paid attention to choosing only hands-on classes that not only teach you the theory but, more importantly, how they are used in the real world.

1. Jenkins, From Zero To Hero: Become a DevOps Jenkins Master

This course covers all the fundamentals about Jenkins and teaches you everything you need to know to set up a Jenkins build pipeline, starting with continuous inspection (build, test, and static analysis) all the way to continuous deployment(deploy to staging and production).

2. Jenkins: Automating your delivery pipeline [Coursera Project]

If you are looking for a hands-on project, something you can complete in a few hours by following step-by-step instructions, then this Coursera project is perfect.

Top 5 Udemy Course to Learn Ansible in 2027 - Best of Lot

2026-09-20T07:48:30.343-07:00

If you are in the DevOps space, then you might have heard about Ansible, one of the powerful tools for infrastructure automation. In the past, when you need to set up a server for your application, you need to go to each server and install all the software and verify it. This slow, manual, and painful server setup process is over, with tools like Ansible, Chef, Puppet, and Salt making their way. These are the tools that promote the idea of Infrastructure as code which also brings the added benefit of versioning and scaling when it comes to infrastructure automation.

This is really important if you want to build a new server and scale as building new servers for your application can take a lot of time but you can reduce them by using automation tools like Chef and Ansible.

If you are working towards a career in DevOps, you are already a DevOps champion in your team, then learning about Ansible is a good idea, and you have come to the right place.

In the past, I have shared DevOps RoadMap, best DevOps Courses, and books, and in this article, I will share some of the best courses to learn Ansible in 2027.

I have made the best efforts to include both beginners and advanced classes so that you can learn Ansible from scratch and take your Ansible skill to the next level with plugins and modules if you already know Ansible.

What is Ansible? What problem does it solve?

If you don't know what Ansible is or have heard the name Ansible the first time, let me give you a quick overview. Ansible is a tool for automating the server setup part. Suppose you have worked as a developer and have ever set up your UAT and production environment. In that case, you know that there is a lot of effort involved in getting your server ready before running or installing your application.

You need to manually install software like Java, Tomcat, and Apache on each server, which can take a long time even if you have a handful of serves. Thankfully, all that can be automated now using Ansible.

All you need to do is create an Ansible playbook, much like a script, and then Ansible will do the setup and installation for you.

It's not that Ansible is the only tool that can do that as you also have Puppet, Chef, and SaltStack. Still, Ansible is probably the most straightforward tool as it can do all this using SSH, while others like Puppet require a dedicated agent installed on each server.

Ansible script, called Ansible playbook, can be written using YAML (Yet Another Markup Language), which reads like English and doesn't require a lot of learning.

It's also backed by RedHat and can be customized using many Python plugins; this makes Ansible a perfect choice for server setup and automation. These courses are good places to kick-start your Ansible journey.

5 Best Udemy Online Training Courses to learn Ansible for DevOps in 2027

Now that you know what Ansible is and how it can help with server setup, automation, and scalability, let's dive into some of the best courses to learn Ansible in depth. As I have said, the list includes both beginner and advanced Ansible courses to learn from scratch and level up your Ansible skills.

1. Ansible for the Absolute Beginner - Hands-On - DevOps

This is my #1 course for anyone who wants to learn Ansible from scratch. It's one of the best Ansible beginner courses and will teach you step by step how to write Ansible playing book, build Ansible inventory files, and deploy software on several hosts.

The best part of the course is that it has hands-on exercises for writing Ansible investors, which you can practice in your browser. It also introduces YAML, which is used to write Ansible build scripts, also known as Playbook.

Packed with 2 hours of content, this course will teach you everything you need to learn to automate your web server deployment.

Talking about social proof, this course has been trusted by more than 47,750 students who speak volumes about its quality. If you want to learn Ansible in 2027, this is the course you should join.

2. Mastering Ansible [Udemy Course]

This is another beginner-level course that provides a complete guide to configuration management and orchestration with Ansible. If you like project-based learning or fan of learn-by-doing, then this course is for you.

The course is designed as a journey through configuring a realistic application stack from the ground up. This means, Instead of going page-by-page through the Ansible documentation, topics are ordered to align with the growing complexity of our application as you build it up and refactor it.

It's another course I highly recommend to beginners learning Ansible. If you want to learn how to do configuration management with Ansible and how to create a very clean and sound ansible-playbook, then this course is for you.

3. Mastering Ansible Automation - Step by Step

If you want to start a career in IT automation and learn Ansible from the ground up, then this is the right course for you. In this course, Shikhar Verma will teach you Ansible Step by Step.

This is a very detailed course, and you will learn about things like implementing Ansible playbooks, writing YAML scripts, variables, scopes, modules, inventories, etc. The good thing is there I a guided exercise for all sections, which means you will be learning by doing.

The course provides an introduction to Ansible and shows many ways to use this tool and create a solid automation pipeline. If you can connect with an instructor, then this is an excellent course to learn Ansible.

4. Ansible Advanced - Hands-On - DevOps

As I have said at the start of this article, you will find both beginners and advanced Ansible courses on this, and keeping that promise, here is a course to learn and practice advanced topics in Ansible, including Roles, Jinja2 Lookups, Filter.

You should take this course only after taking any of the first three courses, ideally the first one in the list, Ansible for the Absolute Beginner because this course is from the same instructor, Mumshad Mannambeth.

This is the second course in the series on Ansible, and in this course, you will learn some advanced concepts in Ansible and some real-life use cases like writing custom modules.

Btw, there are a couple of things that are different between beginner and this course, like the OS used in the beginner course was CentOS, but this one uses Debian, which may take some time to set up the environment.

5. Hands-on Ansible

This is a great course to learn Ansible on Pluralsight. The course starts with orchestration and change management fundamentals then moves to how Ansible works.

You will also build your test environment and, along the way, go through several practical examples and features that Ansible provides.

After going through this course, you will be able to run ad-hoc commands across all your systems, write playbooks, and create roles using the hundreds of modules that come with Ansible. The course also has many hands-on demos to show how to implement your automation tasks.

Overall a great course to learn Ansible, but you need a Pluralsight membership to access this course, which costs around $299 per year. Alternatively, you can sign up for the 10-day free trial and take this course for free.

That's all about the Top 5 Udemy courses to learn Ansible in 2027. As I have said, Ansible is an excellent tool to keep up to your sleeve, particularly for DevOps engineers. You can use Ansible to automate your production configuration. It can create package with right configuration depending upon environment like different configuration for development and production environment.

As a senior developer, you should also know about Ansible to play with those Ansible playbooks and understand how my servers are set up. You can also learn Ansible if you want a career in DevOps; it's definitely worth it.

Top 5 Udemy Courses to learn JVM Internals, Memory Management, GC and Performance Tuning in Java in 2027

2026-09-20T07:46:22.316-07:00

For a senior Java developer, it's essential to know how JVM works and how to troubleshoot issues with respect to memory, most notably memory leaks in Java applications and servers like Tomcat. You might be thinking, how come memory leaks in Java? Isn't memory is managed by JVM and Garbage collector? Well, that's true, but poor coding or just a bit of carelessness can cause memory leaks in Java. If you don't know how to configure JVM, troubleshoot memory-related problems on the heap, and stack, you will struggle at a higher level. That's why it's essential for experienced Java developers to spend some time learning these advanced skills as their experience grows.

If you are thinking on the same line and interested in learning JVM internals, memory management, GC, and Performance tuning this year then you have come to the right place.

In the past, I have shared some of the books and articles to learn about JVM internals and the Garbage collection, and today, I'll share some of the online courses you can join to learn JVM internals and performance tuning.

There are actually not many courses out there to learn JVM internals and Garbage collection algorithms in detail, but luckily there is one series in Pluarlasight that explores JVM internals in good detail covering ClassLoading, Memory Management, and Security.

That's where I have learned some useful information and continue to go whenever I need to refresh my knowledge.

Along with that, there are a couple of excellent courses on Udemy as well, which teach you JVM internals and memory management. If you are serious about taking your Java skills to the next level, I strongly suggest you learn more about JVM internals; it's one topic that can separate an experienced Java developer from a Java developer with some years of experience.

5 Best Udemy Courses to learn JVM Internals, GC, and Memory Management in 2027

As I have said, there are not many excellent courses to learn about JVM internals, memory management, and Garbage collection tuning online. These are somewhat considered advanced topic, and many Java developer just doesn't bother to learn about them.

But things are changing as performance is becoming significant, and senior Java developers are expected to know more about JVM than they currently do.

1. Java Application Performance and Memory Management

This is another excellent course to learn about JVM internals like Jut in time compilation, Garbage Collection, Heap, Stack, and Metaspace, and even GraalVM. You will even learn about how JIT compiler works, C1 and C2 compiler and how JVM makes memory vs performance trade off.

In this JVM training course, instructor Matt GreenCroft of Virtual Pair Programmers has demonstrated his extensive knowledge of JVM and what a Java developer should know about JVM. The first provides a brief overview of JVM along with some history and then moves on to more useful stuff like selecting a JVM, JVM memory, Garbage collection, etc.

The course is neither too long nor too short for the topic. Within 10 hours, you will learn some critical things about JVM and walk out with a solid understanding of Garbage Collection and learn how to tune the JVM and make good coding choices to ensure your applications perform optimally.

2. Java Memory Management [Udemy]

This is an excellent online training course for Java professionals, particularly experienced Java developers, who need an in-depth understanding of how memory works in Java.

In this course, you'll learn about how JVM memory is divided into different areas like a heap, stack, metaspace, etc. You will also learn about what kinds of memory leaks are possible in Java, and how to avoid them.

In addition, you'll learn about tools that can be used to analyze the performance of your applications and detect inefficient memory usages, such as objects which are taking up too much memory or problems causing inefficient garbage collection.

The best part of the course is that you will not just learn about how to find these problems but also some real-world tips to solve those issues in your Java Application.

In short, a great course to learn about JVM memory, garbage collection, tuning the VM, and avoiding memory leaks in Java, and highly recommend it to all Java Programmers.

3. Understanding the Java Virtual Machine: Memory Management

Pluralsight has a fantastic series on JVM, known as "Understanding the Java Virtual Machine" by Kevin Jones. It's a three-part series where each part covers key JVM concepts like Memory Management, Class loading and Reflection, and Security.

This course is the first part of the series and covers all aspects of Garbage collection in Java, including how memory is split into generations and managed. And how the different Garbage Collectors like Concurrent Mark Sweep and G1 Garbage Collector do their job.

The course also covers some advanced concepts which allow you to interact with the garbage collection, like Soft Reference, Weak reference, and Phantom Reference classes.

4. Understanding the Java Virtual Machine: Security

This is the third part of the series "Understanding the Java Virtual Machine" on Pluralsight, and it's focused on Security. If you remember, Java security is built around the idea of permissions and policy. Java Code is granted permissions based on the currently in-force policy.

In this course, you will learn how the security manager and access controller work hand-in-hand to provide this security. The course also covers how to set a security manager and how to set up and edit a policy file to grant the levels of permissions that code needs.

Finally, we cover the idea of 'privileged scope,' which allows code to be granted some permission even when code around them should cause the grant to fail.

Overall a comprehensive course to learn JVM Security in-depth and a must for any Senior Java developer who want to master JVM internals.

5. Understanding the Java Virtual Machine: Class Loading and Reflection

This is the second part of the series, "Understanding the Java Virtual Machine," and it's focused on Classloading and Reflection.

Though it's not required to go through this course in any order, you can just choose the topic you want to learn first and then explore further.

In this course, you will learn about how class loading mechanisms work and how to write class loaders. Once you understand this concept, you can understand how things like hot deployment of classes in Java applications and how the side-by-side loading of classes work. You will also learn about how class loaders work in Java.

Another topic that is covered by this course is Reflection, another tool that helps you to interact with JVM. Java has a rich type system and rich metadata. Reflection is the mechanism by which you can examine that metadata at runtime and use that information to build rich applications like tools, IDEs like Eclipse and IntelliJIDEA, etc.

That's all about some of the best Udemy courses to learn JVM internals, Garbage Collection, and Memory management in 2027. You will also learn how to hunt memory leaks and fix them in Java applications in Java. As I have said in the past, then there are not many excellent courses to learn JVM internals and Garbage collection, but these are the best I have got so far.

You can also combine these courses with books like Java Performance The Definitive Guide to get the best of both worlds.

Top 5 Udemy Courses to Learn Microservices and SOA (Service Oriented Architecture) in Java 2027 - Best Of Lot

2026-09-18T07:01:31.018-07:00

Hello guys, Service-Oriented Architecture (SOA) and Microservice Architecture are essential skills for modern Java developers as most of the Java applications developed today follow SOA and Microservice architecture or their variants. Good knowledge of SOA architecture not only helps you to understand your current project better but also can give your career a boost, especially to senior Java developers who want to become software or solution architects. In the past, I have shared some books for aspiring software architects, and you can also use these courses along with those to master your architecture and solution design skills.

Anyway, SOA architecture provides an alternative to monolith architecture and focuses on small applications providing dedicated services. Some of the common examples of SOA architecture are Web Services and Representational State Transfer (REST) architecture, which is very common in the Java world.

When I was learning SOA last year, I was looking for an online training course that can provide me enough theory and some real-world practical experience, but I didn't find a single one that fits my requirements.

Most of the online courses which I found suffered from two main problems: being too technical from the start, and taking too much of a theoretical approach, while I was needed a balanced course that is neither too much theoretical, neither too thin on theory.

My quest for the best course to learn SOA brought me a couple of useful ones like the Service-Oriented Architecture course on Coursera, which is also part of the Software Design and Architecture Specialization and offered by the University of Alberta.

This course tackles both problems, and it will help make you understand the business behind SOA before it jumps into technology. As you'll not only learn about the fundamentals of SOA, including architecture, services, service types, reuse, and composition but also see some real-world solutions built using SOA.

Finally, you'll learn about the importance of designing a standard semantic model for all SOA services, and after completing the course, you will have knowledge of all the tools needed to implement the SOA architecture in your project.

5 Best Udemy Courses to Learn SOA and Microservice Architecture in 2027

If you want, you can directly jump on the Service Oriented Architecture course on Coursera it's a good one but if you need more choices, here are some of the other useful SOA courses for programmers.

1. Microservices Architecture

This online course will teach you how to transform your monolith into organized, maintainable, and scalable services, leveraging the microservices architecture. It's actually one of the best online courses to learn about Microservice Architecture and the pros and cons of this architecture.

While there are many courses to learn how to implement Microservice architecture using Spring Boot, Quarkus, MicroNaut, and other frameworks, there are not many courses that explain you to why you need Microservice Architecture, its pros, and cons, and why it's the best architecture for cloud-native Java applications.

This course will teach you all the information you need about Microservice architecture. It's created by Packet publication, and it's packed with some of the most up-to-date information on Microservice architecture and SOA, including Serverless architecture which is taking the software architecture by storm. The course is packed with 4.5 hours of content and also provides a certificate of completion.

2. Service-Oriented Architecture [Coursera]

This is my favorite and probably the best course to learn Service Oriented Architecture online. As I told you before it's based on an understanding of architectural styles and you will review architectures for web applications before exploring the basics of Service-Oriented Architecture (SOA) in two approaches: Web Services (WS*) and Representational State Transfer (REST) architecture.

The course is also part of Software Design and Architecture Specialization, which is a recommended resource for Java developers aspiring to become software architects.

The specialization also includes a Capstone Project in which you will connect a Java-based Android application with Elasticsearch, a web service with a REST application programmer interface (API).

By the way, if you find Coursera courses and specialization useful then you should also join the Coursera Plus, a subscription plan from Coursera which provides you unlimited access to their most popular courses, specialization, professional certificate, and guided projects. It cost around $399/year but its complete worth your money as you get unlimited certificates

3. Real-World SOA: Analysis and Design

For example, this specialization also covers 5 following courses:

1. Fundamentals of Visualization with Tableau
2. Essential Design Principles for Tableau
3. Visual Analytics with Tableau
4. Creating Dashboards and Storytelling with Tableau

It cost around $399/year, but it's completely worth your money as you get unlimited certificates.

Talking about social proof, more than 37,876 students have already benefitted from this course, and it has, on average, 4.7 ratings from close to 6,410 rating participants, which are simply phenomenal. Still, no surprise gave me the experience and knowledge of Kirill Eremenko and the SuperDataScience Team.

Top 5 Udemy Courses to Learn HTML 5 and CSS 3 in 2027 - Best of Lot

2026-09-18T06:56:52.258-07:00

Hello guys, if you are learning Web Development or thinking about becoming a Web Developer, you have come to the right place. Earlier, I shared the 2027 Web Developer RoadMap, and today, I'll talk about HTML and CSS and share some valuable resources to learn them in depth. There are three pillars of Web Development, HTML, CSS, and JavaScript. HTML provides structure, CSS provides the style, and JavaScript provides interactive experienced. The HTML stands for Hypertext Markup Language, and it's one of the oldest technology I know. I first learned about HTML on my college day, promising 20 years back, when we were happy to see a list of heading in different colors.

HTML has come a long way since then, with HTML 5 bringing some of the cool features. The same goes for CSS, the stylish part of your web. It is as old as HTML but improved a lot.

Nowadays, people prefer to use a CSS framework like Bootstrap rather than writing their own stylesheet from scratch. However, a good knowledge of CSS, mainly CSS3, is essential for any web developer.

As I have said many times, if you want to become a better and modern web developer, you must put effort into mastering these three pillars of web development.

In the past, I have shared some books, courses, and websites to learn JavaScript, and today, I'll share some of the best routes to learn HTML 5 and CSS, the other two pillars of Web Development.

But, if you hurry and don't have time to go through the whole article, I suggest you check out The Web Developer Bootcamp by Colt Steele, the single best resource to learn Web Development, including HTML, CSS, JavaScript, and many more.

5 Best Udemy Courses to Learn HTML and CSS for Web Development in 2027

Jonas is one of the best instructors in Udemy, and his courses are top quality. I first came through Jonas through his comprehensive The Complete JavaScript Course 2027, which is another hands-on course focusing on building real projects rather than just teaching concepts. If you want to learn JavaScript together with HTML 5 and CSS, I highly recommend that course.

2. Advanced CSS and Sass: Flexbox, Grid, Animations, and More!

This is one of the most advanced CSS courses and one of the most popular routes on CSS in Udemy. The course has got, on average, 4.8 ratings from close to 50,000 students, which is unbelievable.

Kudos to Jonas Schmemann for creating such an excellent course, the instructor of the previous session, which is #1 in Udemy for HTML 5 and CSS.

Jonas is a great instructor, and his explanations are clear and concise, and examples, use cases are well thought out. He also makes an effort to point out common mistakes and misconceptions, which is crucial for becoming a master CSS developer.

As I have said, CSS has changed a lot in the last decade, and whatever you know about it might be outdated. Have you been coding CSS for some time but want to take your game to the next level? Then this is the perfect course for you.

3. HTML5 + CSS3 + Bootstrap: The Beginner Web Design Course [Udemy]

But, if you don't want to join, you can still get this course for free by taking advantage of their 10-day Free Pass, which provides 200 minutes of access to all of their classes, including this one.

That's all about some of the best Udemy courses to learn HTML 5 and CSS for Web Development in 2027. As I have said, these are two pillars of Web Development, and every Web Developer should have a good command of HTML5 and CSS to develop and troubleshoot any Web Application.

Some new technologies and frameworks came up like Bootstrap and Flexbox, but still, CSS Fundamentals are critical, and so is HTML 5.

I have also shared the 2027 Web Developer RoadMap, which provides a complete guide on becoming a Web developer from scratch. You can use that roadmap and these courses to kick-start your HTML and CSS journey and become the Web Developer you always wanted to be.
