Clean software architecture reduces technical debt by standardizing modular decomposition, enforcing dependency rules, and isolating domains. Applying SOLID principles and explicit boundaries ensures maintainable, scalable systems across monoliths and microservices.

Applying DDD principles requires defining explicit bounded contexts to isolate business domains. You detail entities and dependencies within these contexts to achieve modular decomposition and align software structure with business capabilities.

The best way to reduce coupling and increase cohesion in microservices is by defining explicit architectural boundaries. Domain-driven design and separation of concerns ensure services remain modular, testable, and aligned with isolated business domains.

Clean architecture works for refactoring existing monolithic applications by guiding modular decomposition and enforcing dependency rules. You establish explicit boundaries and domain isolation to improve testability and scalability without requiring a full rewrite.

You should not use Domain-Driven Design for software decomposition when the project lacks complex business logic or clear domain boundaries. DDD adds structural overhead that provides little value for simple CRUD applications or purely data-driven systems.
