Encapsulation
Encapsulating the internals of a service through a carefully defined service boundary that does not expose internals of a service is important. Maintaining loose coupling in microservices is important to realizing the benefits of a microservices approach. If we are not careful, our microservices can become coupled. Once these services become coupled we can lose a lot of the value in a microservices architecture, like independent lifecycles. Deploying and managing a microservices-based application with tightly coupled services can be more complex than deploying and managing a monolith. If the deployment of a service needs to be closely coordinated with other services, there is likely coupling as a result.
