Azure in-place virtual machine migration eliminates reboots during critical security updates
We continue to add new platform reliability and availability features to our infrastructure to ensure that customers have the best experience.
Critical security updates for host operating systems previously caused a reboot. Now, most virtual machines benefit from Azure in-place virtual machine migration that only pauses them for up to 30 seconds, while the local temporary disk and memory state are preserved.
Your virtual machines already benefit from this capability for certain critical security updates. With an upcoming platform update later in 2016, we’ll eliminate the need for virtual machine reboot for most patches on host operating systems. Our goal is to eliminate the need for virtual machine reboots for all updates to host operating systems.
