The general mechanism for information flow of our microservices is quite simple and straightforward. It should always be kept in mind when implementing any microservice for our sample enterprise. Meaning, we should agree on the enterprise architecture level to keep some of the fundamental mechanisms and modes of implementations across all of the microservices as uniform. The internal implementation and technologies, or even the development languages, could be different.
Note that this is a generic microservice implementation mechanism, which we use just for our sample enterprise here. It's not a generic way just for any type of microservice though it is quite a common one. We keep it simple for the purpose of understanding and learning the core concepts.
