Eureka is a service discovery server and client library open-sourced by Netflix. When a microservice instance starts, it registers itself with the Eureka server and sends periodic heartbeats, and other services look up the target's address in the registry to call it. It was built to solve the problem of instance addresses changing frequently in cloud environments and became widely used through Spring Cloud. Consul, etcd, and ZooKeeper are alternatives with a similar role.
