hexagonal

Hexagonal architecture isolates domain logic from infrastructure components like databases and message brokers, enabling flexible and testable applications through clear separation of concerns between domain, application, and infrastructure layers.

You separate business logic by using adapters to connect your domain to external payment gateways and databases without changing the core domain code, ensuring business rules remain infrastructure-agnostic.

Yes, implementing hexagonal architecture requires prior knowledge of domain-driven design concepts and software architecture patterns to properly structure the domain, application, and infrastructure layers.

The best way to make software architecture infrastructure-agnostic is to isolate domain logic using flexible adapters, allowing you to swap infrastructure layers like databases and message brokers without altering domain code.

You should use flexible adapters when you need to connect your isolated domain logic to different infrastructure layers, such as swapping payment gateways or message brokers, without modifying the underlying business rules.

Isolating domain logic from HTTP frameworks and databases allows for easier testing, swapping, and scaling of applications by ensuring infrastructure changes do not impact core business rules.
