Microservices: Decomposing Applications for Testability and Deployability
summary
Microservice architecture decomposes a large monolith into independently deployable services with private databases, enabling automated pipelines that cut lead time and raise deployment frequency (Amazon deploys every 11.6 seconds). Cross-service transactions use the saga pattern instead of two‑phase commit; queries use CQRS or API composition; integration uses consumer-driven contract testing; operations rely on container platforms like Kubernetes and monitoring via log aggregation and distributed tracing. Complexity and distributed failures are the main trade-offs.
