Gateway API vs Ingress: Why Modern Kubernetes Traffic Management Uses Attachment, Not Annotations Ingress is still valid, but it stopped evolving. Gateway API gives Kubernetes teams a cleaner resource model for shared edge infrastructure, richer routing, and safer multi-namespace ownership. TL;DR Gateway API is the practical successor to Kubernetes Ingress for teams that need more than host and path routing. Instead of collapsing infrastructure, TLS, and application routing into one resource plus controller-specific annotations, it separates concerns across GatewayClass, Gateway, and HTTPRoute. That gives platform teams explicit entry points, application teams structured routing rules, and both sides a safer attachment model for shared gateways. The result is better portability, clearer ownership, richer HTTP routing, and a migration path that does not require an all-at-once cutover. Gateway API separates infrastructure ownership from routing ownership, replacing annotation-heavy in...
