To help organizations optimize cloud costs and management, we’re excited to introduce hibernation for virtual machines (VMs) in Azure DevTest Labs, now in public preview. The new hibernation feature in Azure DevTest Labs helps customers control and reduce costs by pausing VMs while preserving their state, making it easy to resume work without losing progress. Once a VM is placed in a hibernated state, users aren't charged for the compute cost of the VM, just as they aren't charged for it in a stopped (deallocated) state. Hibernation costs only include storage (OS disk, data disks) and networking resources (IPs, etc.) attached to the VM.
