## Motivation
The Endpoints API has provided a simple and straightforward way of
tracking network endpoints in Kubernetes. Unfortunately as Kubernetes clusters
and Services have gotten larger, limitations of that API became more visible.
Most notably, those included challenges with scaling to larger numbers of
network endpoints.
Since all network endpoints for a Service were stored in a single Endpoints
resource, those resources could get quite large. That affected the performance
of Kubernetes components (notably the master control plane) and resulted in
significant amounts of network traffic and processing when Endpoints changed.
EndpointSlices help you mitigate those issues as well as provide an extensible
platform for additional features such as topological routing.
