Azure Spot Virtual Machines

Azure VMs using unused capacity at deep discounts that can be evicted when Azure needs the capacity.

Definition

Spot VMs offer discounts of up to about 90 percent with no SLA. An eviction policy determines whether evicted VMs are deallocated or deleted, and a maximum price can be set. Scheduled Events give a short notice before eviction.

Example

A batch rendering pool runs on Spot VMs in a scale set with eviction policy set to Delete.

Exam tip

Spot VMs are for interruptible workloads only; they have no availability SLA.
