Hotpatching Now Available in Preview for Windows Server VMs on Azure with Desktop Experience
Introduction
Hotpatching is a new feature in Azure that allows customers to apply software updates to their Windows Server VMs without the need for a reboot. This feature is now available in preview and is available for Windows Server VMs on Azure with Desktop Experience. In this blog post, we will take a look at what hotpatching is and how it works to provide a more efficient and reliable patching experience.
What is Hotpatching?
Hotpatching is an innovative new feature that allows customers to patch their Windows Server VMs without the need for a reboot. This feature is available for Windows Server VMs on Azure with Desktop Experience and is currently in preview mode. Hotpatching works by allowing customers to apply software updates to their VMs without the need to take the VM offline or restart it. The update is applied while the VM is running and is applied in a matter of seconds. This allows customers to keep their VMs up and running during patching and eliminates the need for costly and time-consuming maintenance windows.
How does Hotpatching work?
Hotpatching works by leveraging the High Availability feature in Azure. This feature allows VMs to be moved to a different node in the same datacenter without the need for a reboot. When hotpatching is enabled, the Azure platform will perform the update on a different node in the same datacenter as the VM. This allows the update to be applied without taking the VM offline or restarting it.
Benefits of Hotpatching
Using hotpatching provides customers with a number of benefits. First, it eliminates the need for costly and time-consuming maintenance windows. This allows customers to keep their VMs up and running during patching, reducing downtime and increasing uptime. Second, hotpatching eliminates the need to take VMs offline or restart them, reducing the time and effort required to apply updates. Finally, hotpatching is faster and more reliable than traditional patching methods.
How to enable Hotpatching
Enabling hotpatching is easy and can be done in a few simple steps. First, customers need to enable the High Availability feature in Azure. This can be done in the Azure portal or via PowerShell. Once the feature is enabled, customers need to enable hotpatching in the Windows Server VM. This can be done by adding the hotpatching feature to the VM in the Azure portal. Once the feature is enabled, hotpatching will be enabled on the VM.
Conclusion
Hotpatching is a new feature in Azure that allows customers to apply software updates to their Windows Server VMs without the need for a reboot. This feature is now available in preview for Windows Server VMs on Azure with Desktop Experience and provides customers with a more efficient and reliable patching experience. By eliminating the need for costly and time-consuming maintenance windows and reducing the time and effort required to apply updates, hotpatching can help customers keep their VMs up and running with minimal downtime.
