Which of the following virtual machine (VM) types can create significant cost savings for a business, particularly in the case of non-continuous workloads?

Ans: Spot VMs Explanation:

Spot VMs allows organizations to take advantage of Microsoft’s unused capacity with significant cost savings. At any point when Azure needs the capacity back, the Azure infrastructure evicts Spot VMs. Therefore, Spot VMs are great for workloads that can handle interruptions such as batch processing jobs, dev/test environments, large compute workloads, and more.

The amount of available capacity can vary based on size, region, time of day, and more. When deploying Spot VMs, Azure allocates the VMs if there is capacity available, but it provides is no SLA for these VMs. A Spot VM offers no high availability guarantees. When Azure needs the capacity back, the Azure infrastructure evicts a Spot VM with 30 seconds' notice.
