Microservice design principles
There are several different microservices design principles available. Different terms are likely to be used in different places. In this book, we will refer to the microservices design principles as follows:
- High cohesion among services: A microservice should have one single focus and the sole responsibility for that action. It should not change as a result of other related services. Services should be easily rewritable so that we can achieve scalability, reliability, and flexibility. It should handle a single business function and domain-specific functionality.
- Autonomous service: A service should independently handle its work without the help of any other services. It should not be tightly integrated with any other service; it should remain loosely coupled in nature. By autonomous, we mean that a microservice should not change because of the external components with which it interacts. Autonomous services honor contracts and interfaces. They should be stateless...
