FEATURE STATE: Kubernetes v1.21 [deprecated] Note: This feature, specifically the alpha topologyKeys API, is deprecated since Kubernetes v1.21. Topology Aware Hints, introduced in Kubernetes v1.21, provide similar functionality. Service Topology enables a service to route traffic based upon the Node topology of the cluster. For example, a service can specify that traffic be preferentially routed to endpoints that are on the same Node as the client, or in the same availability zone.
FEATURE STATE: Kubernetes v1.23 [beta] Topology Aware Hints enable topology aware routing by including suggestions for how clients should consume endpoints. This approach adds metadata to enable consumers of EndpointSlice and / or Endpoints objects, so that traffic to those network endpoints can be routed closer to where it originated.
For example, you can route traffic within a locality to reduce costs, or to improve network performance.
Motivation Kubernetes clusters are increasingly deployed in multi-zone environments.
