Azure Virtual Machine extensions are small applications that provide post-deployment configuration and automation on Azure VMs.
The ability to automatically upgrade VM extensions is now available for Azure Virtual Machines and Virtual Machine Scale Sets. If the automatic extension upgrade feature is enabled for an extension on a VM or a VM scale set, the extension is upgraded automatically whenever the extension publisher releases a new version. Azure manages the upgrade rollout and the upgrades are safely applied following availability-first principles, keeping your environments more secure and up to date.
