The Kubernetes Gateway API is a standard for configuring traffic ingress and routing. Its role-oriented design lets developers manage the ingress elements affecting their applications while a platform provides the shared gateway infrastructure. section 8.4.2
A service mesh can provide these capabilities because its control plane manages the proxies that route traffic to applications. This makes ingress part of a shared integration point that can also support traffic control, resiliency, and security. Introduce those capabilities as the platform needs them rather than requiring every proxy feature from the start. section 8.4.2
Platform-managed ingress
A platform can deploy Istio to provide a self-service ingress experience backed by managed domain names. An illustrated application route uses an Istio VirtualService; that resource is an Istio-specific example, not a Gateway API resource. section 8.4.2
