Spot VMs for interruptible workloads
Quillan Research runs a large batch rendering job that can tolerate interruptions and restart from checkpoints. The team wants to reduce compute costs by using unused Azure capacity, accepting that VMs may be evicted. Which option should you use?
- A.Azure Spot Virtual Machines
- B.Reserved VM instances for one year
- C.Dedicated hosts
- D.VMs in a proximity placement group
Show answer and explanation
Correct answer: A. Azure Spot Virtual Machines
Why: Azure Spot VMs use spare capacity at a significant discount and can be evicted when Azure needs the capacity back, which suits interruptible batch jobs. Reservations require a term commitment for steady workloads, dedicated hosts provide physical server isolation, and proximity placement groups reduce latency between VMs.
