The Art of Batch API Design - Having a batch API in your system might be a very efficient way for accessing resources and doing actions with them. Instead of calling 50 time the same resource, you can do 50 actions in one call.
However, batch APIs bring with them complexities you should be aware of, and this article does a great job in outlining them and guiding you through the proper way to implement batch APIs.

Modernizing Applications with the 7Rs Strategy - Systems Modernization is one of the biggest challenges these days, and organizations spend billion of dollars in converting their legacy systems to modern ones that can run in the cloud.
When approaching a modernization process, it’s important to be familiar with the various strategies that can be used, and this article describes these specific strategies, including the pros and cons of each one.


From Monolith to Modular Monolith to Microservices  - Most architects are familiar with the Monolith → Microservices path, when we migrate a monolith system to a microservices based one. But, as this article by Sepehr Mohseni argues, this doesn’t have to be the case, and there might be another stop in the way.

Master legacy systems modernization with AWS Transform in this new course

Modernizing legacy systems is one of the most sought-after skills in the modern software and cloud industry today.

We all know the struggle: legacy systems - whether built on older versions of .NET Framework and Java, or running on-premises via VMWare or Mainframes - are often a significant headache for organizations. They consume massive amounts of budget and effort, yet the modernization process is notoriously difficult, cumbersome, and prone to failure.

In fact, most modernization projects fail, and it's no wonder - legacy code can be difficult to understand, and the original developers are often long gone.

But there is finally a solution to this challenge.

AWS Transform is a new service in AWS, which does just that - it transforms and modernizes legacy systems.

AWS Transform uses an array of AI agents to discover, assess, analyze and transform legacy code to modern languages, and it does that in minutes, not months.

And the best part? It's free :-)

To help you master this shift, I’ve created a brand-new course: Modernize Your Systems with AWS Transform. My goal is to turn system modernization into an effortless, high-speed, and even fun experience.

In this course we're going to learn about the new and exciting service.

Here are some of the topics we'll cover:

- What is system modernization and why you should do it
- Fundamentals of AWS Transform
- User roles in AWS Transform
- The flow of modernizing legacy systems
- Configuring and using custom transformations
- And lots more...

Now, I wanted to make this course as practical as possible, and therefore its focus is on AWS Transform hands on.

In this course we're actually going to modernize not one, but two real apps. One from .NET Framework to .NET, and another one from Angular to React.

Note that you don't have to be .NET or Angular developer to benefit from this course, I walk you through all the steps and provide all the code.

Of course, these are just examples and you can do much more than that, but these are quite common modernization scenarios.

By the end of this course you'll be able to design and run a full modernization process using one of the most exciting services that were created in recent years.

To celebrate the launch, I’m offering the course at a deep discount. You can enroll today for just $9.99.

So enroll now to the Modernize Your Systems with AWS Transform course, and become an expert in systems modernization.

Note: The discount expires in a few days, so hurry up!

So, that was the March 2026 edition of theVar.
