Although EndpointSlices may eventually replace Endpoints, many Kubernetes
components still rely on Endpoints. For now, enabling EndpointSlices should be
seen as an addition to Endpoints in a cluster, not a replacement for them.
The EndpointSlice resource was designed to address shortcomings in a earlier
resource: Endpoints. Some Kubernetes components and third-party applications
continue to use and rely on Endpoints. Whilst that remains the case,
EndpointSlices should be seen as an addition to Endpoints in a cluster, not as
an outright replacement.

## API fields
Some fields in the EndpointSlice API are feature-gated.
- The `EndpointSliceNodeName` feature gate controls access to the `nodeName`
field. This is an alpha feature that is disabled by default.
- The `EndpointSliceTerminating` feature gate controls access to the `serving`
and `terminating` condition fields. This is an alpha feature that is disabled
by default.
## Using EndpointSlices
With EndpointSlices fully enabled in your cluster, you should see corresponding
EndpointSlice resources for each Endpoints resource. In addition to supporting
existing Endpoints functionality, EndpointSlices include new bits of information
such as topology. They will allow for greater scalability and extensibility of
network endpoints in your cluster.
