What is Arquitetura Hexagonal?

Hexagonal Architecture (also known as Ports and Adapters Architecture) is a software design pattern that aims to create loosely coupled application components. It does this by separating the business logic from the external concerns, such as the user interface, database, or other external systems. The core idea is to place the business logic at the center (the hexagon) and surround it with interfaces (ports) that define how the application interacts with the outside world. Adapters then implement these interfaces to connect to specific technologies or systems. This allows the application to be easily tested, maintained, and adapted to new technologies without affecting the core business logic. It's commonly used in applications where flexibility, testability, and maintainability are high priorities.
