An availability group has been configured with 2 replicas (primary P and secondary S1) for automatic failover and a Listener within the virtual network VNET1 in Region 1 (e.g. The scenario is depicted in the figure below. This also allows testing disaster recovery processes when desired.

This allows quickly recovering SQL Server from a situation impacting a full Azure region (e.g. In this scenario, an Availability Group is expanded with one or more secondary replicas in a different Azure region. Having Availability Groups spanning two or more Azure regions enables two important SQL Server scenarios on Azure Infrastructure Services: disaster recovery and geo-distributed read scale-out.

After connecting 2 or more VNETs, their VMs can connect to each other, and even join the same Windows domain, as if they were part of the same VNET. This builds on top of Microsoft Azure’s new support to connect VNETs in different Azure regions via secure tunnels. Any regions available today (4 in United States, 2 in Europe, 2 in Asia Pacific, 2 in Japan, and 1 in Brazil). This is illustrated in the figure below:ĪlwaysOn Availability Groups between Microsoft Azure RegionsĪvailability Groups are now supported between different Azure Regions. The Listener is a DNS name that client applications, inside or outside the VNET (inside or outside of Microsoft Azure), can use in their connection string to connect to the primary replica of the Availability Group. The replicas correspond to SQL Server instances hosted by separate Virtual Machines within the same Azure Virtual Network (VNET). To ensure SQL Server high availability on Azure Infrastructure Services, you configure an Availability Group, generally with 2 replicas (1 primary, 1 secondary) for automatic failover and a Listener.
due to physical hardware failures), platform upgrades, or your own patching of the guest OS or SQL Server. In the context of Azure Infrastructure Services, this significantly increases the availability of these databases during Microsoft Azure’s VM Service Healing (e.g. When detecting these conditions, the Availability Group fails over a group of databases to a secondary replica. SQL service being down or losing connectivity).

Today we updated our official documentation describing how to configure these.ĪlwaysOn Availability Groups on Microsoft Azure Infrastructure ServicesĪvailability Groups, released in SQL Server 2012 and enhanced in SQL Server 2014, detect conditions impacting SQL Server availability (e.g. We’re excited to announce that AlwaysOn Availability Groups are now supported between Microsoft Azure Regions. Last year we announced the support of SQL Server AlwaysOn Availability Groups on Microsoft Azure Infrastructure Services.
