architecture-patterns

Structure backend code using clean architecture by enforcing strict dependency rules to separate concerns, ensuring your core domain logic remains independent of external frameworks and databases for maximum testability.

Hexagonal architecture decouples the core domain from external concerns via ports and adapters, while domain-driven design focuses on modeling complex business domains using strategic and tactical patterns for maintainable systems.

Use domain-driven design for microservice decomposition when you need to model complex business domains, enabling strategic and tactical patterns to cleanly separate bounded contexts and structure scalable backend systems.

Decouple database logic from domain models in Python by implementing hexagonal architecture with ports and adapters, decoupling the core domain from external concerns to ensure your business logic remains independent.

Yes, you can use these architectural patterns to refactor a monolithic application by structuring your codebase with distinct layers, ports and adapters, and domain-centric modeling to achieve a scalable architecture.
