Traffic flows from Client through Gateway and HTTPRoute to your application Pods

NGINX Ingress Controller Equivalent:

In NGINX Ingress, this flow is handled by a single Ingress resource that combines Gateway and HTTPRoute functionality. The NGINX Ingress Controller acts as the Gateway, and the Ingress resource defines the routing rules.
