This is a multi-module maven project which has following modules:

Start the projects from command line using:

mvn spring-boot:run

Follow below steps to see services in action:

1. Start service discovery server.

2. To test that the eureka server load balance between the clients we need to start two instances/processes of micro-service-eureka-client spring boot application. Just run mvn spring-boot:run from two different command windows/terminals.

3. Start the consumer spring boot application micro-service-consumer-eureka-client which uses @LoadBalanced RestTemplate to enable Netflix Ribbon for load balancing the requests. This eureka client exposes following endpoint:

   GET http://localhost:8989/eureka/client/consume

   which internally makes a call to http://eureka-client/greeting. Thing to notice here is that we are calling the client by name i.e. eureka-client and ribbon will take care of forwarding the request to appropriate instance of the eureka-client.

This project also contains a gateway service module micro-services-gateway which makes use of Netflix Zuul Proxy to forward requests to the appropriate backend service eureka-client (Whoever registers itself to Eureka Service Registry).

GET http://localhost:9090/eureka-client/greeting
