To create the cluster, follow these steps: Repeat the steps on the other SQL Server VM.Īfter the cluster feature has been added to each SQL Server VM, you're ready to create the Windows Server Failover Cluster. Select Next until you get to the Server Features section. Select the Add roles and features link on the dashboard. To do so, follow these steps:Ĭonnect to the SQL Server virtual machine through the Remote Desktop Protocol (RDP) using a domain account that has permissions to create objects in AD, such as the CORP\Install domain account created in the prerequisites article. Add failover cluster featureĪdd the failover cluster feature to both SQL Server VMs. The Always On availability group lives on top of the Windows Server Failover Cluster infrastructure, so before deploying your availability group, you must first configure the Windows Server Failover Cluster, which includes adding the feature, creating the cluster, and setting the cluster IP address. The tutorial assumes you have a basic understanding of SQL Server Always On availability groups. Member of SQL Server sysadmin fixed server role for each instance of SQL Server Database mirroring endpoint: 5022 or any available port With two secondary IPs assigned to each VMĪ domain account used by the SQL Server service for each machine In separate subnets within an Azure Virtual Network Each VM in two different Azure availability zones or the same availability set The following table lists the prerequisites that you need to complete before starting this tutorial: Requirement Time estimate: Assuming your prerequisites are complete, this tutorial should take about 30 minutes to complete. The complete tutorial creates a Windows Server Failover Cluster, and an availability group with a two SQL Server replicas and a listener. ![]() This tutorial shows how to create an Always On availability group for SQL Server on Azure Virtual Machines (VMs) within multiple subnets. ![]() If you've already created your availability group in a single subnet, you can migrate it to a multi-subnet environment. Simplify your deployment and eliminate the need for an Azure Load Balancer or distributed network name (DNN) for your Always On availability group by creating your SQL Server virtual machines (VMs) in multiple subnets within the same Azure virtual network. There are many methods to deploy an availability group.
