 ## Configure the VMs for high availability
 The best way to protect an application that's running on Azure against VM reboots and downtime is to configure the VMs for high availability.

 ### Memory-preserving updates

Some are platform infrastructure updates on the host operating system that can be applied without a reboot of the VMs.

 These memory-preserving updates are accomplished with technology that enables in-place live migration. When it is being updated, the VM is placed in a *paused* state. This state preserves the memory in RAM while the underlying host operating system receives the necessary updates and patches. The VM is resumed within 30 seconds of being paused. After the VM is resumed, its clock is automatically synchronized.

 ### Azure Security Center and Windows Update
 Azure Security Center monitors daily Windows and Linux VMs for missing operating-system updates. Security Center retrieves a list of available security and critical updates from Windows Update or Windows Server Update Services (WSUS), depending on which service is configured on a Windows VM. Security Center also checks for the latest updates for Linux systems. If your VM is missing a system update, Security Center recommends that you apply system updates. The application of these system updates is controlled through the Security Center in Azure portal. After you apply some updates, VM reboots might be required. For more information, see [Apply system updates in Azure Security Center](../articles/security-center/security-center-apply-system-updates.md).
 
-Like on-premises servers, Azure does not push Windows Updates to Windows Azure VMs since these machines are intended to be managed by the user.  Customers are, however encouraged to leave the automatic Windows Update setting enabled. Automatic installation of updates in Windows Update can also cause reboots to occur after the updates are applied.

 ### Other situations affecting the availability of your VM
 There are other cases in which Azure might actively suspend the use of a VM. You'll receive email notifications before this action is taken, so you'll have a chance to resolve the underlying issues. Examples of issues that affect VM availability include security violations and the expiration of payment methods.
