 <2> Specify the minimum number machines of the specified type that must remain in the specified zone after the cluster autoscaler initiates cluster scaling. If running in AWS, GCP, Azure, {rh-openstack}, or vSphere, this value can be set to `0`. For other providers, do not set this value to `0`.
 +
 You can save on costs by setting this value to `0` for use cases such as running expensive or limited-usage hardware that is used for specialized workloads, or by scaling a machine set with extra large machines. The cluster autoscaler scales the machine set down to zero if the machines are not in use.

-Do not set the `spec.minReplicas` value to `0` for the three compute plane machine sets that are created during the {product-title} installation process for an installer provisioned infrastructure.

-<3> Specify the maximum number machines of the specified type that the cluster autoscaler can deploy in the specified AWS zone after it initiates cluster scaling.
