To organize folder structure and define dependency boundaries, apply feature-based or layer-based structuring along with SOLID principles. This enforces module boundaries, prevents circular coupling, and clarifies domain versus data layer separation for maintainable systems.

The best way to apply SOLID principles and dependency injection during an architecture review is to evaluate interface contracts and module dependencies. This reduces coupling and verifies that Repository, Service, Factory, and Strategy patterns are implemented correctly.

You need layered architecture and design patterns like Repository or Strategy when separating domain logic from data access to improve testability. This approach structures dependency boundaries clearly, ensuring your backend application remains scalable and maintainable.

To plan error handling, configuration, and testing strategies for a new microservice, define clear architectural standards and interface contracts first. This establishes dependency injection rules and structural boundaries to guide performance optimization and testing guidance.

Yes, this architectural review approach works for both web and backend applications. It provides design pattern recommendations and dependency rules that reduce coupling and improve maintainability across diverse software systems.
