title: Kubernetes networking: is service information stored in every node's IPTable?
body: <p>Can someone tell me why the service hop won't become a single point of failure?</p>
  <p>In <a href="https://kubernetes.io/docs/concepts/services-networking/_print/" rel="nofollow noreferrer">Kubernete Service</a>, I see an hop of Service between the client and Pods: <a href="https://i.stack.imgur.com/CDw8f.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CDw8f.png" alt="enter image description here" /></a></p>
  <p>I guess all service's (let's say there are 5000 of services and each service has 3 Pods) routing info are stored in the IPTable of each node?</p>
