Hexagonal Architecture, first introduced by Alistair Cockburn, aims to decouple the core logic of an application from external concerns like databases, user interfaces, and third-party services. The "hexagon" represents the application's core, which communicates with the outside world through "ports" (interfaces) and "adapters" (implementations). Core Components
