Structure a backend project using Clean Architecture and Domain-Driven Design by organizing code into distinct layers for domain logic, application use cases, and infrastructure, ensuring dependencies point inward toward the domain core for maintainable and testable systems.

The best way to refactor a monolithic application is to apply proven architecture patterns like Hexagonal Architecture and Domain-Driven Design to isolate business logic from infrastructure, improving testability and scalability during the transition.

Hexagonal Architecture works by isolating backend business logic inside an application core, interacting with external systems like databases or APIs through defined ports and adapters, ensuring the core domain remains independent and highly testable.

You need Domain-Driven Design for complex backend systems when maintaining a clear separation between business logic and infrastructure, allowing you to scale effectively and manage domain complexity through structured architectural patterns.

Yes, this architecture patterns guidance includes concrete code examples and recommended directory structures for Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to help you implement maintainable and scalable backend systems.

Limitations of applying Clean Architecture to a new microservice include potential boilerplate overhead and complexity from strict layer separation, which requires careful dependency management to maintain the intended scalability and testability benefits.
