Microservices Communication Template

This template helps you design and implement effective communication patterns between microservices, including synchronous and asynchronous messaging approaches.

Sample Prompt

Design microservices communication for an e-commerce platform:
- REST API communication between user service and order service
- Event-driven messaging for inventory updates using message queues
- Service discovery and load balancing configuration
- Circuit breaker implementation for resilient service calls
- API versioning strategy for backward compatibility
- Monitoring and tracing for distributed service interactions

What This Template Covers

Communication patterns including REST APIs, message queues, and event streaming
Service discovery and registration for dynamic service location
Load balancing and fault tolerance strategies for service calls
Data consistency approaches including eventual consistency and sagas
API design with versioning and backward compatibility considerations
Monitoring and observability for distributed system health and performance

Best Practices

Choose appropriate communication patterns for each use case (sync vs async)
Implement circuit breakers to prevent cascade failures
Use service mesh for advanced traffic management and security
Design for eventual consistency when appropriate for business requirements
Implement proper timeout and retry policies for resilient communication
Version APIs carefully to maintain backward compatibility
Monitor service dependencies and communication health
Use correlation IDs for request tracing across service boundaries

When to Use This Template

Designing communication architecture for new microservices systems
Improving reliability and performance of existing service interactions
Implementing event-driven architectures for scalable systems
Adding fault tolerance and resilience to distributed applications
Optimizing service-to-service communication for better performance
