Implementing the Eureka service discovery and client-side load balancing

Although it is acceptable to call microservice endpoints directly from the Eureka server, explicitly through its machine name and ports, Spring Cloud offers automatic service discovery which makes RESTful service execution free from hardcoding the service URL. When it comes to duplicate instances for backup and recovery purposes, this recipe will define the concept of client-side load balancing wherein an algorithm is used to determine the most viable and healthy instance to utilize in executing the endpoints.

Getting started

Create another Eureka instance that will contain a @Controller, which will consume RESTful services from the Eureka registry applying client-side load balancing built by SpringCloudNetflixRibbon module.

How to do it...

Let us implement client-side load balancing by following these steps:

1. First, create a Maven project ch10-eureka-client that contains pom.xml with SpringCloudFinchley dependencies. Just...
