architecture-patterns

Backend architecture patterns like Clean Architecture and Hexagonal Architecture structure systems into layered components, separating core logic from external interfaces to ensure long-term maintainability and testability.

You implement Domain-Driven Design by defining core domain concepts like entities, value objects, and aggregates, using provided Python code examples to structure domain logic and isolate business rules effectively.

Use Hexagonal Architecture when you need to isolate business logic from external concerns through ports and adapters, allowing backend systems to remain testable and scalable regardless of external changes.

You set up Clean Architecture by organizing backend code into distinct layered structures, using provided Python implementations to define boundaries between domain entities, use cases, and interface adapters.

Yes, the guidance provides practical Python implementations for each backend architecture pattern, including specific directory structures and code examples for concepts like DDD aggregates and adapter interfaces.

Separating domain logic through ports and adapters isolates core business rules from external dependencies, making backend software highly testable without needing to mock entire infrastructure layers.
