Kubernetes has some great helpers that allow us to drop a service in and satisfy most requirements for service discovery and loadbalancing. Service discovery out of the box will make a dns request through Kube-DNS. Kube-DNS is (soon to be coredns) a pod running dnsmasq with a custom integration to watch events straight off the Kubernetes api. Loadbalancing is provided out of the box by Kube-proxy. Which provides TCP stream balancing inside the cluster.
