Apply clean architecture to structure large codebases by enforcing the dependency rule and separating concerns. This provides reference playbooks and templates to define clear boundaries, ensuring maintainability and testable module interfaces.

Hexagonal architecture uses ports-and-adapters to isolate business logic, while domain-driven design models complex business domains. Both enforce clear boundaries and inward dependencies to organize code and support durable workflows.

Use domain-driven design for large or complex domains requiring clear boundaries, maintainability, and team coordination. It organizes code dependencies and supports durable workflows across complex business processes.

Enforce the dependency rule in layered architecture by defining module interfaces with inward dependencies. This maintains separation of concerns and testable boundaries by ensuring outer layers depend on inner layers.

Yes, hexagonal architecture supports migrations in large codebases using ports-and-adapters concepts. It provides guidelines and templates to isolate business logic and establish testable boundaries for maintainable service rewrites.

Clean architecture introduces structural overhead that may not suit small projects lacking complex domains. The dependency rule and layered separation are designed for maintainability and team coordination in large codebases, which are less critical in simpler applications.
