An Egress Gateway (see Figure 3) is a dedicated Istio proxy through which all egress traffic passes - a single exit point from the mesh. Istio in theory has little to do with Kubernetes or Mesos, except that it intitially assumed everyone will be running apps in Kubernetes (because Istio is from google). In this article, I use both Istio's side car approach for pod to pod communication and its Ingress capabilities acting as an HTTP gateway to your application. working with istio-ctl Chapter 4: Istio Gateway. It then uses a few of its features, including routing, mutual TLS, Ingress Gateway, and telemetry.
