Application Modernization in Baby Steps [Video]

Application Modernization in Baby Steps [Video] - This tutorial considers updating a legacy Java app, including looking at microservices, updating the runtime, and more. Application Modernization is not trivial. Before you get started, make sure you understand why you want to modernize applications.

Let's update an app.

Are you curious to learn how to modernize 10-year-old Java applications to gain benefits from the cloud? Do you want to try this yourself following step-by-step instructions? Then you should check out my repo, which I’m going to describe in this article and the embedded  video.

Application Modernization Strategies

Application Modernization is not trivial. Before you get started, make sure you understand why you want to modernize applications. The main benefits can be categorized into three buckets. More agility, better user experiences, and reduced costs. To learn more about these benefits, check out my  rabbit video. For me, the number one reason is more agility, or in other words, the ability adapt to changes and to innovate faster.

There are several different strategies how to handle legacy applications. One strategy is to simply retire them if they are not used anymore. Another strategy is not to touch them, for example, if you don’t find developers with the appropriate skills anymore. The easiest way to move existing applications into the cloud is the “lift and shift” approach which doesn’t require any code changes. For me, as a developer, the most exciting application modernization strategies are Containerization and Re-factoring. These strategies give you the maximal benefits of cloud-native architectures and I demonstrate them in my sample.
