Azure Arc-enabled servers VMware Frequently Asked Questions

This article addresses frequently asked questions about Arc-enabled servers on virtual machines running in VMware vSphere environments.

What is Azure Arc?

Azure Arc is the overarching brand for a suite of Azure hybrid products that extend specific Azure public cloud services and/or management capabilities beyond Azure to on-premises environments and 3rd-party clouds. Azure Arc-enabled server, for example, allows you to use the same Azure management tools you would with a VM running in Azure with a VM running on-premises in a VMware vSphere cluster.

What's the difference between Azure Arc-enabled servers and Azure Arc-enabled VMware vSphere?


Arc-enabled VMware vSphere refers to the Arc integration with VMware vSphere environments. VMware vSphere environment. Azure Arc-enabled VMware vSphere is currently in Public Preview. Arc-enabled VMware vSphere supports vSphere environments anywhere, either on-premises as well Azure VMware Solution (AVS), VMware Cloud on AWS, and Google Cloud VMware Engine.

The easiest way to think of this is as follows:

  • Azure Arc-enabled servers interact on the guest operating system level, with no awareness of the underlying infrastructure fabric and the virtualization platform that it’s running on. Since Arc-enabled servers also support bare-metal machines, there may, in fact, not even be a host hypervisor in some cases.

  • Azure Arc-enabled VMware vSphere is a superset of Arc-enabled servers that extends management capabilities beyond the guest operating system to the VM itself. This provides lifecycle management and CRUD (Create, Read, Update, and Delete) operations on a VMware vSphere VM. These lifecycle management capabilities are exposed in the Azure portal and look and feel just like a regular Azure VM. See What is Azure Arc-enabled VMware vSphere to learn more.


Azure Arc-enabled VMware vSphere also provides guest operating system management—in fact, it uses the same components as Azure Arc-enabled servers. However, during Public Preview, not all Azure services supported by Azure Arc-enabled servers are available for Arc-enabled VMware vSphere - currently, Azure Monitor, Update Management, and Microsoft Defender for Cloud are not supported. In addition, Arc-enabled VMware vSphere is supported by Azure VMware Solution (AVS).

Can I use Azure Arc-enabled server on VMs running in VMware environments?

Yes. Azure Arc-enabled servers work with VMs running in an on-premises VMware vSphere environment as well as Azure VMware Solution (AVS) and support the full breadth of guest management capabilities across security, monitoring, and governance.

Which operating systems does Azure Arc-enabled servers work with?

Azure Arc-enabled servers and/or Azure Arc-enabled VMware vSphere work with all supported versions of Windows Server and major distributions of Linux. As mentioned, even though Arc-enabled servers work with VMware vSphere virtual machines, the Connected Machine agent has no notion of familiarity with the underlying infrastructure fabric and virtualization layer.

Should I use Arc-enabled servers or Arc-enabled VMware vSphere, and can I use both?

While Azure Arc-enabled servers and Azure Arc-enabled VMware vSphere can be used in conjunction with one another, please note that this will produce dual representations in the Azure portal of the same underlying virtual machine. This scenario can potentially introduce a “duplicate” guest management experience and is not advisable.
