Today’s (SQL) Tip…
Availability Groups are now supported between different Azure Regions. Any regions available today (4 in United States, 2 in Europe, 2 in Asia Pacific, 2 in Japan, and 1 in Brazil).
This builds on top of Microsoft Azure’s new support to connect VNETs in different Azure regions via secure tunnels. 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.
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.
