03. Spring Cloud & Eureka

Eureka, created by Netflix, is responsible for the registration and discovery microservices. Spring has incorporated Eureka into Spring Cloud, making it even easier to stand up a Eureka server.

Eureka consists of a server and a client-side component. The server component will be the registry in which all the microservices register their availability. The microservices use the Eureka client to register; once the registration is complete, it notifies the server of its existence.
