Gateway API is an official Kubernetes project focused on L4 and L7 routing in Kubernetes. This project represents the next generation of Kubernetes Ingress, Load Balancing, and Service Mesh APIs. From the outset, it has been designed to be generic, expressive, and role-oriented. Most of the configuration in this API is contained in the Routing layer. These protocol-specific resources (HTTPRoute, GRPCRoute, etc) enable advanced routing capabilities for both Ingress and Mesh. When using Gateway API to manage ingress traffic, the Gateway resource defines a point of access at which traffic can be routed across multiple contexts -- for example, from outside the cluster to inside the cluster (north/south traffic). Each Gateway is associated with a GatewayClass, which describes the actual kind of gateway controller that will handle traffic for the Gateway; individual routing resources (such as HTTPRoute) are then associated with the Gateway resources.
