See the original article here. eureka.client.serviceUrl.defaultZone indicates the location of the Eureka server. This cache is refreshed every 30 seconds by default ('eureka.client.registryFetchIntervalSeconds`). Pour appeler un Microservice, il suffira de piocher dans cette liste d'instances qu'Eureka expose via une API REST. For the demo we will disable that using registerWithEureka flag. Clients also have an in-memory cache of eureka registrations (so they don’t have to go to the registry for every single request to a service).+ By default every Eureka server is also a Eureka client and requires (at least one) service URL to locate a peer. Please note that the Eureka server also caches the delta updates every 3 minutes, so the Eureka client can receive the same delta instances multiple times.
