Gateway API is replacing Kubernetes Ingress as the standard for traffic management at scale. Unlike Ingress, which relies on controller-specific annotations and lacks proper role separation, Gateway API provides a structured model with GatewayClass, Gateway, and Route resources that enable platform teams to manage infrastructure while application teams control routing rules. It supports advanced features like GRPC routing, service mesh integration through GAMMA, and safe cross-namespace delegation via ReferenceGrant. The API includes conformance testing for portability across controllers and vendors, making it suitable for multi-cluster, multi-team enterprise environments where consistent, scalable networking is critical.
