Using Ephemeral OS Disks in Azure for Stateless VMs
DevOps Team Lead in Content
Azure OS Disks serve as the primary storage for Azure Virtual Machines. Persistent disks provide reliability and robust backup guarantees for stateful VMs, but these disks cost money. If your VM is stateless, however, you can use an ephemeral OS disk, which has no additional storage cost beyond the base compute cost of the VM itself. These ephemeral disks can also be deployed and reimaged more quickly than persistent disks. In this lab, you will have the opportunity to experiment with ephemeral OS disks by building and reimaging a stateless VM.
