We are thrilled to announce the public preview of low-priority virtual machines (VMs) on VM scale sets. Low-priority VMs allow users to run their workloads at a fraction of the price, enabling significant cost savings. This offering has been available through our Azure Batch service since May 2017, and because we have seen great customer success we are expanding it to VM scale sets.
This is a great option for resilient, fault-tolerant applications as these VMs are allocated using our unutilized capacity and can, therefore, be evicted. Low-priority VMs are available through VM scale sets with up to an 80 percent discount.
Read about it in the Azure blog.
