The new Kubernetes Gateway API with Istio and Anthos Service Mesh (ASM)

Gateway API is an open source project managed by the SIG-NETWORK community. It is an API (collection of resources) that model service networking in Kubernetes. These resources — GatewayClassGatewayHTTPRouteTCPRoute, etc., as well as the Kubernetes Service resource - aim to evolve Kubernetes service networking through expressive, extensible, and role-oriented interfaces that are implemented by many vendors and have broad industry support.

The new Gateway APIs aim to take the learnings from various Kubernetes ingress implementations, including Istio, to build a standardized vendor neutral API.
