Limitation for ingress

• multi-tenancy
• namespace isolation
• no RBAC for features

• For instance: 2 backend services are managed by 2 different teams having to share the same ingress resources

• Specific config are specified using annotations that are specific to the ingress controller

Definition

• Official Kubernetes project focuses on layer 4(i.e: transport layer) and layer 7(i.e: application layer)
• represents next genarations of ingress, load balancing, and service mesh APIs

  Roles

• Infrastructure provider: set up gateway class, define what the underlying network infrastructure would be. Such as nginx, traefik, other LB
• cluster operators: instance of the gateway class
• application dev: the http route, tcproute, grpcroute, and others

Ingress vs Gateway API

• In Gateway API, the protocol is more declarive, tls config and route kind are more explicit,

• Canary deployment:
