Developing Reactive Microservices
In this chapter, we will learn how to develop reactive microservices, that is, how to develop non-blocking synchronous REST APIs and asynchronous event-driven services. We will also learn about how to choose between these two alternatives. Finally, we will see how to create and run manual and automated tests of a reactive microservice landscape.
As already described in Chapter 1, Introduction to Microservices, the foundation for reactive systems is that they are message-driven—they use asynchronous communication. This enables them to be elastic, in other words, scalable and resilient, meaning that they will be tolerant of failures. Elasticity and resilience together will enable a reactive system to be responsive. ...
