Azure Update Management Part 3 – Schedule an Update Deployment

0

In today’s post of the Azure Update Management Series, we will take a look at how to schedule an update deployment. In the first and second post of this series, we looked at introduction and overview of the solution and also how to enroll Azure VMs.

As we all know by now, Update Management Solution is free offering from Microsoft which allows you to perform patch assessment and compliance for your Azure VMs both Windows and Linux machines, along with on-premises VMs and VMs running on other cloud service providers.

Also, an important to note is that when WSUS is used in conjunction with Azure Update Management, any deployment scheduled in the Azure Update Management solution will not take precedence.

To create a new deployment schedule, go to your Azure Automation Account, under Update Managment, select Schedule update management.

This will bring up a New update deployment pane, fill out the below details.
