Kubernetes Gateway API is the new specification released by CNCF to standardize the Kubernetes Ingress traffic. Now, what if a service is configured as High Availability (HA)? (Say it is in a different cloud environment and you have to access it from the Gateway; i.e., multicluster, multi-cloud scenario.) In this article, we will showcase how to use the Gateway API spec to configure gateways for multicluster setup. 

Multicluster Kubernetes Gateway Demo Overview

We have two clusters: one in EKS (primary) and the other in GKE (remote). I have deployed Istio in both the clusters and the setup is primary-remote Istio installation. Istio is used as the controller to implement the Gateway API resources.
