What is Architecture Hexagonale?

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 core logic of the application from the external concerns such as the user interface, databases, or message queues. The core application interacts with the outside world through 'ports' (interfaces), and specific implementations for these external concerns are provided by 'adapters'. This allows the application to be easily tested, maintained, and adapted to different technologies without modifying the core business logic. It is commonly used in systems where flexibility and adaptability are crucial.
