In the Failover Cluster Manager console, set the Static IP Address property of the IP Address resource you identified in the previous step to the front-end IP address of the Azure load balancer.This IP resource Name will be used as a variable $IPResourceName in the powershell script in Step 8. In the Failover Cluster Manager console, identify the name of the IP Address resource of the newly created Client Access Point.In the Failover Cluster Manager console, create a Client Access Point representing the listener.In the Failover Cluster Manager console, identify the name of the cluster network to which both nodes are connected and note it down which needs to be used as a variable $ClusterNetworkName in the powershell script in Step 8.' Create the Availability Group’ Section in the Microsoft site if you need more details. Create an availability group in SQL Server from SQL Server Management Studio same as the way how you do for the on premise Virtual Machines.This section gives you a quick summary of what needs to be done from a SQL Server DBA perspective once the Azure Team completed done the load balancer configuration. Create the load balancer and configure the IP addressĬonfigure the cluster to use the load balancer IP address.
The overview of the process is given here. This often will be taking care by the Azure Team in an organization. This link explains in detail about the 4 steps to configure the Load Balancer in the Azure Portal. This article will give you the steps to configure the Always On Listener in Azure servers. But in Azure servers, it is not the same way as it is in the on premise servers. This will automatically create the cluster roles in the Failover Cluster Manager wizard. Generally, in on-premises servers, the Always On configuration is simple enough that we can create it by right clicking the Add Listener option in SSMS. Support from both the Azure\Cloud Team and SQL Server DBA Team are required for the successful implementation of Always On in Azure Servers. If an availability group spans multiple regions, each region needs a load balancer. The load balancer will have the same IP address for the availability group listener. This article gives you a brief explanation about the steps that needs to be done for this.Īn Availability Group (AG) requires a load balancer when the SQL Server instances are running on Azure virtual machines. This Microsoft article link will give you a detailed explanation about how Always On needs to be configured in Azure virtual machines that are running with Azure Resource Manager (ARM). These differences reflect some of the unique characteristics of the storage and network infrastructure services in the Microsoft cloud environment. The Always On configuration of SQL Server in Azure Virtual Machines differs in multiple ways from the on-premise implementations.
