Introducing service discovery
Service discovery is probably the most important support function required to make a landscape of cooperating microservices production-ready. Netflix Eureka was the first discovery server supported by Spring Cloud.
We are strictly speaking about a service for service discovery, but instead of referring to it as a service discovery service, it will simply be referred to as a discovery service. When referring to an actual implementation of service discovery, like Netflix Eureka, the term discovery server will be used.
We will see how easy it is to register microservices with Netflix Eureka when using Spring Cloud. We will also learn how a client can use Spring Cloud LoadBalancer to send HTTP requests to one of the instances registered in Netflix Eureka. Finally, we will try scaling the microservices up and down, together with running some disruptive tests to see how Netflix Eureka can handle different types of fault scenarios.Before we jump into the implementation...
