Case Study: Refactoring A Monolith Into A Cloud Native App (Part 4)

In this blog series, we have used the SpringTrader application as an example of an existing legacy Java app to modernize. In Parts 1, 2, and 3, we got the app up and running on Pivotal Cloud Foundry and began refactoring the architecture. This post extends the effort. At the end, you will clearly see how we have improved scalability, resiliency, and maintainability. Code examples and downloads are included.

Refactoring Towards Expressive REST APIs: Let Your Code Be Your Guide

In this post, Pivotal Labs Engineering Manager, David Julia, provides an example of a problematic RESTful JSON API and an approach for refactoring it. When API designs are implicit, they don’t reveal and enable the intended API usage, and they become very difficult to implement. In today’s world of cloud connectivity and developer community, poorly designed API can greatly slow down or stop software service adoption in its tracks, not to mention the public feedback for poor APIs. David’s approach, and the related code, clearly explain some of the key considerations.

Case Study: Refactoring A Monolith Into A Cloud Native App (Part 1)

Migrating legacy, monolith apps on to Cloud Native architectures is a challenge. In this post, we delve into the details of taking an existing Java app, refactoring it, and deploying it on Pivotal Cloud Foundry. This is the first part in a series, and uses an actual legacy application, SpringTrader, as an example.

Injecting Cloud Native Thinking Into Java With Spring Boot

In the first part of a two part episode on Spring Boot and Spring Cloud, Josh Long and host Coté talk about the Spring Initializr and Spring Boot. They discuss the idea of doing process-based design (a key part of cloud native application development) in Java and how Initializr and Boot help with that. Also, they discuss how Boot can help with more governance and controls, while at the same time giving developers more autonomy and speed.
