  12. Hybrid Capabilities:

    • While primarily designed for Azure VMs, Azure Update Manager can be extended to manage updates for on-premises VMs or VMs hosted in other cloud environments using Azure Automation and Azure Automation Hybrid Runbook Workers.


  14. Cost Management:

    • Azure Update Manager itself is a free service. You are only charged for any underlying resources you use, such as Azure Automation and Log Analytics, which may be required for more advanced monitoring and management features.
