Service Discovery + Ribbon + Hystrix

one instance of weather-app runs over 8080 calls two instances of weather-service (runs on ports 8081 and 8082) load balanced via Ribbon (using RestTemplate @LoadBalanced) and discovered via Eureka discovery service.

When one weather-service instance of the two is down, then Hystrix call the callback method for number of requests (3 I think). Then using because of service discovery, the weather-service will be removed from the discovery service after 30 seconds, and at this time all requests to the weather-service will be redirect to the single up instance of the wather-service.
