Hexagonal Architecture in Microservices Patterns

An important benefit of the hexagonal architectural style is that it decouples the business logic from the presentation and data access logic in the adapters.

The business logic doesn’t depend on either the presentation logic or the data access logic. Because of this decoupling, it’s much easier to test the business logic in isolation.

Another benefit is that it more accurately reflects the architecture of a modern application.

The business logic can be invoked via multiple adapters, each of which implements a particular API or UI.

The business logic can also invoke multiple adapters, each one of which invokes a different external system.

Hexagonal architecture is a great way to describe the architecture of each service in a microservice architecture.
