Which two features are valid only when deploying Cloud Pak for Data on-premises?

In on-premises deployments of IBM Cloud Pak for Data:

Administrators have full control over the number of OpenShift nodes, unlike cloud-managed environments where node scaling may be automatic or abstracted.

Persistent storage is always required and configured by the infrastructure team to meet service requirements and ensure data availability.

Auto-scaling of compute and automatic updates of services are not handled by IBM in on-prem setups.

Network security responsibilities also lie with the deploying organization, not IBM, in an on-premises model.
