How to Use Redis in Infrastructure Microservices

The text discusses using Redis as a message queue, demonstrating its many use cases beyond caching. It highlights the importance of distributed systems and their implications on consistency, availability, and partition tolerance according to the CAP theorem. Event sourcing is also mentioned as a technique that prioritizes availability over consistency. The "Hello World" example of microservice architecture, OrderShop, is used to illustrate Redis' role in event stores and message queues. It explains how communication in distributed systems can be brokered or brokerless, with examples using Redis Lists and Streams. The text also touches upon the use of gRPC for network communication, CQRS pattern, SAGA pattern, and a simple UI to watch events and browse state. Overall, it emphasizes Redis' versatility and flexibility in domain and infrastructure services beyond caching.
