Summary
This chapter dived into the building blocks of a strong microservice architecture. It covered API gateways, explaining their purpose, use cases, and how to implement them for optimal performance, with caching, rate limiting, and response aggregation. The chapter then explored CQRS and event sourcing patterns, along with event streaming, a technology that makes them work. Finally, it discussed Service Registry and discovery, essential for microservices to communicate with each other. This chapter provided the knowledge and practical examples to build a well-designed and scalable microservice infrastructure.
In the next chapter, we will explore testing strategies in depth and cover how to write effective unit and integration tests for your microservices.
