EndpointSlice [glossary]deterministic
EndpointSlices track the IP addresses of Pods for Services.
networking
EndpointSlices track the IP addresses of backend endpoints. EndpointSlices are normally associated with a [Service](#gloss:service) and the backend endpoints typically represent [Pods](#gloss:pod).
One Service can be backed by multiple Pods. Kubernetes represents the backing endpoints of a Service with a set of EndpointSlices that are associated with that Service. The backing endpoints are usually, but not always, pods running in the cluster.
The control plane usually manages EndpointSlices for you automatically. However, EndpointSlices can be defined manually for [Services](#gloss:service) without [selectors](#gloss:selector) specified.
