at the cost of potentially longer delay before identity of new endpoint is
recognized throughout the cluster.

.. note::

CiliumEndpointSlice is a concept that is specific to Cilium and is not
related to `Kubernetes' EndpointSlice`_. Although the names are similar, and
even though the concept of slices in each feature brings similar
improvements for scalability, they address different problems.

Kubernetes' Endpoints and EndpointSlices allow Cilium to make load-balancing
decisions for a particular Service object; Kubernetes' EndpointSlices offer
a scalable way to track Service back-ends within a cluster.

By contrast, CiliumEndpoints and CiliumEndpointSlices are used to make
network routing and policy decisions. So CiliumEndpointSlices focus on
tracking Pods, batching CEPs to reduce the number of updates to propagate
through the API-server on large clusters.

Enabling one does not affect the other.

The CES feature relies on use of CEP. This feature is disabled by default
