Layered architecture in Domain-Driven Design separates concerns across Presentation, Application, Domain, and Infrastructure layers to establish clear boundaries and enforce dependency direction for maintainable software.

To identify bounded contexts and aggregates for DDD alignment, define your core domain concepts and draft minimal interfaces for repositories and domain services to anchor the design and ensure clean domain modeling.

The best way to refactor a monolith using a layered architecture is to establish the four separation layers and enforce dependency direction to prevent architectural erosion during the transition.

You need architectural governance for repository placement when evaluating architecture during code reviews or scaling teams, applying decision criteria to service boundaries to prevent structural decay.

Yes, this approach works for starting a new startup module by providing a structured methodology to shape scalable software using SOLID design principles and DDD-based modeling.

Enforcing dependency direction across presentation and infrastructure layers prevents architectural erosion by ensuring layer boundaries are respected and core domain logic remains isolated.
