Understanding Microservices Communication

Microservices are designed and intended to operate as independently as possible. Still, they need to talk to each other once in a while. In this chapter, you will learn what good communication between microservices looks like and what you should avoid. Microservices sometimes have to communicate with each other; for example, when it comes to validating or aggregating information. Imagine that one microservice needs to get data from another one to then visualize it. The first microservice could, of course, access the database directly, but this might threaten the integrity of the second microservice. This is also dangerous because of the database's structure changes, or even the database itself, which means that the first microservice won't be able to operate anymore. So, for the first database to retrieve reliable information...
