Key CTP 1.3 enhancement: Always On Availability Groups on Linux
In SQL Server v.Next, we continue to add new enhancements for greater availability and higher uptime. A key design principle has been to provide customers with the same HA and DR solutions on all platforms supported by SQL Server. On Windows, Always On depends on Windows Server Failover Clustering (WSFC). On Linux, you can now create Always On Availability Groups, which integrate with Linux-based cluster resource managers to enable automatic monitoring, failure detection and automatic failover during unplanned outages. We started with the popular clustering technology, Pacemaker.
In addition, Availability Groups can now work across Windows and Linux as part of the same Distributed Availability Group. This configuration can accomplish cross-platform migrations without downtime. To learn more, you can read our blog titled “SQL Server on Linux: Mission Critical HADR with Always On Availability Groups”.
That’s a big headline. In the Other Enhancements section, I like resumable online index rebuilds as well.
