The Ports and Adapters (Hexagonal) architecture pattern, also known as the Hexagonal architecture pattern or the Ports and Adapter architecture pattern, is a software architecture pattern that is focused on creating a robust and maintainable software application with a clear separation of concerns.
The pattern uses a hexagonal shape to represent the various components of the application and their interactions, with the core of the hexagon representing the application domain logic and the surrounding edges representing the various input/output ports. The pattern is built around the concept of "ports" and "adapters," where the ports represent the input/output interfaces and the adapters connect the ports to the core application logic.
The key benefit of the Ports and Adapters pattern is its ability to reduce the complexity of the application by separating the core business logic from the external infrastructure. This makes the code easier to maintain and test, and allows different parts of the system to be changed independently without affecting the rest of the application.
This pattern is particularly useful for applications that have multiple input/output sources, such as web applications, mobile applications, or other systems that require data integration from multiple sources. It can also be used for legacy systems that need to be updated to keep up with changing business requirements.
