Deep dives

Increased Pace of Software Changes

The podcast highlights the accelerated pace of software updates, contrasting the stable period of Spring Boot 1, which lasted seven years without backward-incompatible changes, to the current rate of updates that occurs every three months. This rapid evolution poses significant challenges for organizations, particularly those with large-scale applications, such as banks managing thousands of applications built on outdated frameworks. The implications of these frequent updates require businesses to invest considerable resources in modernization efforts, making it critical for them to adopt solutions that can streamline this process. As the pace of change increases, it becomes essential for companies to find ways to efficiently adapt their systems.

#301: How many applications are in your organization that need to be kept up to date? More than likely, that number is every application needs to be kept up to date, if for no other reason than to keep your security teams happy. It gets even worse if you have 10s, 100s or even 1000s of applications. How do you make this manageable?

In this episode, we sit down with Jonathan Schneider from Moderne to discuss OpenRewrite, a large-scale software refactoring solution. Jonathan explains how OpenRewrite assists in application modernization, security vulnerability repair, and code quality improvements.
