Azure Arc-enabled servers lets you manage Windows and Linux physical servers and virtual machines hosted outside of Azure, on your corporate network, or other cloud provider. For the purposes of Azure Arc, these machines hosted outside of Azure are considered hybrid machines. The management of hybrid machines in Azure Arc is designed to be consistent with how you manage native Azure virtual machines, using standard Azure constructs such as Azure Policy and applying tags. (For additional information about hybrid environments, see What is a hybrid cloud?)

When you connect your machine to Azure Arc-enabled servers, you can perform many operational functions, just as you would with native Azure virtual machines. Below are some of the key supported actions for connected machines.

For a list of supported regions with Azure Arc-enabled servers, see the Azure products by region page.
In most cases, the location you select when you create the installation script should be the Azure region geographically closest to your machine's location. Data at rest is stored within the Azure geography containing the region you specify, which may also affect your choice of region if you have data residency requirements. If the Azure region your machine connects to has an outage, the connected machine isn't affected, but management operations using Azure may be unable to complete. If there's a regional outage, and if you have multiple locations that support a geographically redundant service, it's best to connect the machines in each location to a different Azure region.
