Azure Batch had retired
Low-Priority VMs on September 30, 2025 and will begin a system-initiated
migration to Spot VMs beginning March 1, 2026. This change aligns Batch with the broader
Azure Spot infrastructure and simplifies the platform’s VM offering.
Impact:
- The migration will occur automatically and be
completed within several days.
- No interruption to existing workloads is
expected.
- Customers will see Spot-based billing beginning
with the March invoice.
Action required:
- No action is required if you choose to continue
using Spot VMs after the migration.
- If you prefer not to transition, you
may migrate your Batch workloads to dedicated (on-demand) compute
nodes before end of February. After this deadline:
- Low-priority VMs can no longer be created.
- Existing Low-priority VMs will be billed at Spot
pricing.
Details:
- All current Low-Priority VMs will automatically run
as Spot VMs after migration.
- Batch-managed pool allocation will handle the
transition seamlessly.
- Existing API/SDK references to Low-Priority VM
properties will automatically allocate Spot capacity without changes to
customer code or configuration.
