on Azure VM

This article introduces Always On availability groups (AG) for SQL Server on Azure Virtual

Machines (VMs).

To get started, see the

Availability group tutorial.

Always On availability groups on Azure Virtual Machines are similar to

Always On availability

and rely on the underlying

Windows Server Failover Cluster. However,

since the virtual machines are hosted in Azure, there are a few additional considerations as

well, such as VM redundancy and routing traffic on the Azure network.

The following diagram illustrates an availability group for SQL Server on Azure VMs:

Note

It’s now possible to lift and shift your availability group solution to SQL Server on Azure

VMs using Azure Migrate. See
