  title: Kubernetes Services Kubernetes EndpointSlices GRPCRoute API
  description: The Kubernetes EndpointSlices API tracks the IP addresses, ports, readiness, and topology information for Pods backing a Service. EndpointSlices replaced the older Endpoints API to improve scalability for large clusters with thousands of pods. A single Service may be backed by multiple EndpointSlices, and the EndpointSlice controller automatically manages their lifecycle in response to pod and Service changes.
