architecture-patterns

To structure a large codebase effectively, apply proven architecture patterns like Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to separate concerns, improve testability, and enable independent component evolution.

Implement domain-driven design and hexagonal architecture by using practical templates and checklists to define module boundaries, establish dependency rules, and configure ports and adapters for your enterprise services.

You need clean architecture when organizing large codebases with multiple bounded contexts, requiring scalable architecture decisions to reduce architectural drift and handle continuously evolving business requirements.

Migrate an existing codebase to ports and adapters architecture by following structured migration steps and templates that guide the transition of domain models and dependency rules across multiple bounded contexts.

Choosing between clean architecture and hexagonal architecture depends on your domain constraints; map your project's specific requirements against each pattern's structural templates to determine the best fit for separating concerns.

A limitation of applying domain-driven design to large codebases is the complexity of managing multiple bounded contexts, requiring strict module boundaries and continuous alignment to prevent architectural drift over time.
