Azure VM Without Availability Set

The VM has no protection from host maintenance or a rack failure, so a platform event takes it offline with no warning.

Detect

ZopNight checks this automatically across Azure, with read-only access to the account.

02

Explain

Every finding says exactly what to change: Move VM into an availability set or zone.

03

Fix

The finding opens with the fix already written out, step by step, so it is one ticket, not an investigation.

Applies to
Virtual Machines on Azure
The fix, by hand
  1. Availability cannot be added to an existing VM. Plan a recreate.
  2. Decide between Availability Zones (preferred for region SLA) and Availability Sets (rack-level fault domains, single-zone).
  3. Snapshot the OS + data disks of the resource; export the ARM template for redeploy.
  4. Recreate the VM in a zone (or zone-redundant scale set / availability set) using the snapshots; reattach disks.
  5. Repoint DNS / load balancer backend pools to the new VM, then deallocate and delete the original.
  6. For horizontally scalable workloads, recreate as a zonal Virtual Machine Scale Set instead. The platform manages distribution.

These are the steps the finding carries in the product.
