Microservices Development with Jakarta EE

Microservices is an architectural style in which code is deployed in small, granular modules. The microservices architecture reduces coupling and increases cohesion. Typically, microservices are implemented as RESTful web services, using JSON to pass data to one another, by invoking HTTP methods (GET, POST, PUT or DELETE) on each other. Since communication between microservices is done via HTTP methods, microservices written in different programming languages can interact with each other. In this chapter, we will cover how we can use Jakarta EE to implement microservices.

In this chapter, we will cover the following topics:

• An introduction to microservices
• Microservices and Jakarta EE
• Developing microservices using Jakarta EE
