Virtualization
The district's on-prem hypervisor environment — what platform it runs, how it survives host failure and balances load, and how snapshots and licensing are managed. Cloud-hosted VMs (Azure / AWS / GCP) belong to Cloud & SaaS Infrastructure, not here — this sub-domain covers only hypervisors the district itself runs.

Environment

Summary of the on-prem hypervisor environment. Cloud-hosted VMs (Azure / AWS / GCP) are captured in Cloud & SaaS Infrastructure (CI-CLD) — not here.

Practice

Failover behavior when a hypervisor host fails. HA at the cluster level keeps VMs running through host failure. Anchor: NIST CSF PR.IR-3, CIS Control 11.

How workloads are distributed across hypervisor hosts. DRS / dynamic resource management keeps load balanced as VMs come and go. Anchor: NIST CSF PR.IR-4, CIS Control 11.

How VM snapshots are managed. Snapshot sprawl degrades performance and storage capacity over time. Anchor: NIST CSF PR.DS-2, PR.IR-3.

Snapshots are not a backup. Used as a backup substitute, they fail when underlying storage fails or is encrypted. This field captures the district's operational understanding of that boundary. Anchor: NIST CSF PR.DS-11, PR.IR-3.

Current licensing model and vendor-concentration risk. K-12 districts running VMware faced 2–10× cost increases at renewal after the 2023 Broadcom acquisition; this field captures where the district sits in that landscape. Anchor: NIST CSF ID.SC-2, ID.RA-3.
