![]() ![]() Under Project details, for Subscription, select the appropriate Azure subscription.Then enter the following information on the Basics tab: On the Create virtual network page, select Create. Search for virtual network in the Marketplace search box, and then select the virtual network tile from Microsoft. Go to your resource group in the Azure portal and select + Create. To create a virtual network and subnet in the new region in the Azure portal: The following table lists details for the local (current) region and what will be set up in the new remote region. Create the network and subnetīefore you create a virtual network and subnet in a new region, decide on the address space, subnet network, cluster IP, and availability group listener IP addresses that you'll use for the remote region. This architecture incurs outbound data charges for data replicated between Azure regions. In this architecture, the replica in the remote region is normally configured with asynchronous commit availability mode and manual failover mode. It's added to the Windows Server failover cluster and can host an availability group replica. The diagram shows a new virtual machine called SQL-VM-3. The following diagram shows how the new architecture looks: To overcome this vulnerability, add a replica in a different Azure region. This architecture is vulnerable to downtime if the Azure region becomes inaccessible. To build this architecture, see the availability group template or tutorial. The availability group replicas can have synchronous commit with automatic failover on SQL-VM-1 and SQL-VM-2. In the deployment shown in the diagram, all virtual machines are in one Azure region. ![]() The following image shows a common deployment of an availability group on Azure virtual machines: The remote region is the new infrastructure that's being added in this tutorial. Mentions of the local region in this article refer to the virtual machines and availability group already configured in the first region. This tutorial builds on the tutorial to manually deploy an availability group in multiple subnets in a single region. You can also use the steps in this article to extend an existing on-premises availability group to Azure. You can use this configuration for disaster recovery (DR). This tutorial explains how to configure an Always On availability group replica for SQL Server on Azure Virtual Machines (VMs) in an Azure region that is remote to the primary replica. ![]()
