Decomposing a monolithic application into microservices requires defining clear service boundaries and selecting appropriate communication protocols. This process demands understanding of architectural principles to properly separate concerns and ensure fault tolerance across distributed systems.

Handling microservices communication involves implementing synchronous patterns like REST or gRPC for direct requests, and asynchronous event-driven patterns for decoupled operations. Selecting the appropriate protocol depends on your specific distributed system requirements.

The circuit breaker pattern enhances microservices resilience by stopping cascading failures when a downstream service becomes unavailable. It monitors fault tolerance thresholds and automatically trips to prevent overloading the distributed system during outages.

Distributed transactions in an event-driven architecture are required when multiple services must maintain data consistency across separate databases. Implementing patterns like sagas manages these complex workflows and ensures fault tolerance without traditional ACID guarantees.

Implementing distributed tracing for fault tolerance requires monitoring requests across microservices to identify latency and failure points. This observability is crucial for diagnosing inter-service communication issues within complex distributed systems.
