 ==== 
 
 The custom metrics autoscaler, unlike the HPA, can scale to zero. If you set the `minReplicaCount` value in the custom metrics autoscaler CR to `0`, the custom metrics autoscaler scales the workload down from 1 to 0 replicas to or up from 0 replicas to 1. This is known as the _activation phase_. After scaling up to 1 replica, the HPA takes control of the scaling. This is known as the _scaling phase_.
