Hexagonal architecture, also called ports and adapters, is a software design approach that helps structure an application by clearly separating the core logic from technical details and external systems. Instead of shaping your app around frameworks, protocols, or storage, you keep your focus on what the application does, and let everything else connect to it through interfaces.

This approach can help structure code more clearly, especially in systems that deal with complex business logic or need to scale certain operations differently.
