Clean architecture is a design approach that enforces separation of concerns and clear boundaries between domains. It helps build scalable software by ensuring modules remain testable, maintainable, and independent of external framework dependencies.

To refactor a monolithic codebase using DDD, you outline bounded contexts, define core entities and use cases, and sketch surrounding interface boundaries. This structured decomposition guides modular implementation and isolates domain logic.

The best way to define bounded contexts is to start by outlining top-level boundaries for the new feature. You identify core domains, define primary use cases, and sketch the surrounding interfaces and dependencies to ensure strict separation of concerns.

Yes, you can use Domain Driven Design principles to improve code quality by applying practical rules for naming, module decomposition, and avoiding common anti-patterns. This enforces testable boundaries and clear separation within existing system codebases.

You should avoid clean architecture when a system lacks complex domain logic or bounded contexts, as enforcing strict boundaries and separation of concerns on simple CRUD applications introduces unnecessary abstraction and structural overhead.
