To design a layered backend architecture, you structure HTTP API components into distinct layers including routes, controllers, services, and repositories. This separation organizes request handling, business logic, and data access to create maintainable and scalable backend systems.

The best way to structure microservices is by separating routes, controllers, services, and repositories into distinct layers. This design isolates HTTP request handling from business logic and data access, facilitating maintainable and scalable microservice systems.

Yes, you can review an existing backend architecture using this layered approach. It provides a framework to evaluate whether your current components like routes, controllers, services, and repositories are structured for optimal maintainability and scalability.

You need a layered architecture when building HTTP APIs or microservices that require high maintainability and scalability. It separates components like routes, controllers, services, and repositories to ensure backend systems remain organized as complexity grows.

Separating services and repositories improves backend maintainability by isolating business logic from data access operations. This layered architecture ensures that changes to data retrieval in repositories do not impact the core services handling application logic.
