service-decomposition

Determining service boundaries requires a structured approach to system decomposition that balances service independence with operational efficiency. You must analyze domain responsibilities to define manageable, deployable services that ensure scalability and maintainability.

Choose microservices over a modular monolith when evaluating system scalability and maintainability demands strict service independence. This architectural decision depends on whether your application requires distributed deployment or if a modular monolith sufficiently meets your operational efficiency needs.

Designing an API Gateway and Backend for Frontend (BFF) pattern involves implementing infrastructure components that handle service discovery and communication. These patterns route client requests efficiently to appropriate microservices while abstracting internal service complexities.

Defining service granularity involves balancing service independence with operational efficiency to avoid overly fine-grained services. You must apply architectural patterns to determine the right level of decomposition for your specific system's scalability and maintainability requirements.

You need a service mesh when your microservices architecture requires dedicated infrastructure components for managing service-to-service communication and discovery. It provides a structured approach to handle complex distributed system interactions and routing reliably.

Breaking down a monolith into microservices creates operational complexity because managing distributed systems introduces communication overhead and infrastructure dependencies. You must carefully determine service boundaries and implement service meshes to maintain operational efficiency.
