Microservices Patterns

microservicesarchitecturepatterns

Microservices add complexity. Patterns manage that complexity.

Essential Patterns

  • API Gateway: single entry point for all clients
  • Circuit Breaker: stop calling failing services
  • Saga: manage distributed transactions
  • CQRS: separate reads from writes
  • Event Sourcing: store changes, not state

Do not start with microservices. Start with a monolith. Extract services when you have a clear boundary and a reason to split.
