In this blog, you will learn about the Kubernetes Ingress Gateway, the Gateway API, and the emerging Gateway API trend, which enables the convergence of Kubernetes and service mesh.
- Ingress, the original gateway for Kubernetes, has a resource model that is too simple to fit into today’s programmable networks.
- The Gateway API, the latest addition to the Kubernetes portal gateway, separates concerns through role delineation and provides cross-namespace support to make it more adaptable to multi-cloud environments. Most API gateways already support it.
- The Gateway API provides a new reference model for the convergence of ingress gateways (north-south) and service mesh (east-west, cross-cluster routing), where there is a partial functional overlap.
