Overview
StatefulSet is the workload API object used to manage stateful applications.
State and identity (name, hostname). It is not guaranteed the same IP address, but the name is constant. The state a StatefuSet pod holds is relevant, we need to be able to get to it, based on a name.
Scaling
A StatefulSet has a Scale sub-resource, allowing it to be controlled by a horizontal pod autoscaler.
