@Rizwan Assad Update Management Center (Preview) is a new-age unified service in Azure to manage and govern updates (Windows and Linux), both on-premises and other cloud platforms, across hybrid environments from a single dashboard. It is built as native functionality on Azure Compute and Azure Arc for Servers platform for ease of use and does not depend on Azure Automation or Azure Monitor Logs, as required by the Azure Automation Update Management feature.
To use Update Management Center, you need to ensure that your machines meet the prerequisites for scheduled patching, which includes setting the patch orchestration of the Azure machines to Azure Orchestrated (Automatic By Platform) and having a maintenance configuration attached to the Azure machine.
I hope this helps! Let me know if you have any further questions.
