In this chapter, we will build our first couple of microservices. We will learn how to create cooperating microservices with minimalistic functionality. In upcoming chapters, we will add more and more functionality to these microservices. By the end of this chapter, we will have a RESTful API exposed by a composite microservice. The composite microservice will call three other microservices using their RESTful API's to create an aggregated response.
The following topics will be covered in this chapter:
- Introducing the microservice landscape
- Generating skeleton microservices
- Adding RESTful APIs
- Adding a composite microservice
- Adding error handling
- Testing the APIs manually
- Adding automated tests of microservices in isolation
- Adding semi-automated tests to a microservice landscape
