What is hexagonal architecture in software development?

Can you explain what hexagonal architecture is?

Hexagonal architecture, also known as the Ports and Adapters pattern, is a software design pattern that emphasizes separation of concerns. It allows the application to be independent of external systems, making it easier to test and maintain.

What are the main benefits of using hexagonal architecture?

The main benefits include improved testability, flexibility in changing external systems, and better organization of code, which leads to easier maintenance.

Can you give me an example of hexagonal architecture in a real application?

Sure! A common example is a web application where the core business logic is isolated from the web framework, database, and other external services. This allows you to swap out the web framework without affecting the core logic.

How does hexagonal architecture compare to MVC?

Hexagonal architecture focuses on the application's core and its interactions with external systems, while MVC (Model-View-Controller) is more about separating concerns within the user interface. Hexagonal can be seen as a broader approach that can incorporate MVC.
