How microservices become autonomous services. Microservices have been used more and more frequently in recent years. The use of many smaller services has made the use of synchronous communication increasingly difficult and complex. This is because synchronous communication ensures close coupling between the individual services and can ensure that if one service fails, a number of others fail at the same time. Typical resilience patterns such as: Circuit-Breaker, Retries, Service Meshes, etc. in turn increase the complexity of the overall system and also only partially solve the real problem. In this presentation, I will show how an event-first mindset can be used to design entire systems in an event-driven way. How microservices become autonomous services that are completely separate from each other and only communicate with each other via events. And how developers can use serverless and FaaS to focus on what is important: delivering business value.
