SQL Server on Azure Virtual Machines: Multi subnet high availability generally available

Published date: 10 November, 2021

You can now simplify your SQL Server on Azure Virtual Machines high availability and disaster recovery configuration by deploying virtual machines in multiple subnets, eliminating the need for an Azure Load Balancer. Multi subnet configuration natively helps you match on-premises experience for connecting to your availability group listener or SQL Server failover cluster instance. Additionally, this feature doesn’t have any limitations on unique port or feature interoperability considerations like distributed network name (DNN) for availability group and failover cluster instance.

Multi subnet configuration is natively supported by all versions of SQL Server and Windows Server Failover Cluster to simplify deployment, maintenance and improve failover time.
