Microservices solve problems, but add complexity. Are you ready?
Service Boundaries¶
- ☐ Domain-driven design for service boundaries
- ☐ Loose coupling, high cohesion
- ☐ API contracts defined
- ☐ Backward compatibility
Communication¶
- ☐ Synchronous (REST/gRPC) vs asynchronous (events/messaging)
- ☐ Service discovery
- ☐ Circuit breaker pattern
- ☐ Retry with exponential backoff
- ☐ Idempotent operations
Data¶
- ☐ Database per service
- ☐ Eventual consistency strategy
- ☐ Saga pattern for distributed transactions
- ☐ Event sourcing (optional)
Observability¶
- ☐ Distributed tracing (Jaeger/Zipkin)
- ☐ Centralized logging
- ☐ Metrics per service
- ☐ Health checks
- ☐ Service mesh (optional)
Deployment¶
- ☐ Independent deployment per service
- ☐ CI/CD per service
- ☐ Feature flags
- ☐ Canary deployments
Warning¶
If you don’t have >10 developers and clear domain boundaries, you probably don’t need microservices. Start with a monolith.
