The Best Thing About the Next Version of SQL Server 2012
AlwaysOn Availability Groups (Clustering + Mirroring + Replication)
Us data plumbers have a killer new HA and scaling tool: AlwaysOn Availability Groups. It’s so important that some of my clients are already planning their 2011/2012 schedule around the deployment. In the past, we’ve struggled with combinations of clustering, log shipping, database mirroring, and replication to get the right mix of performance and availability. These tools work great, but using them all correctly requires a lot of training and experience. Microsoft heard our complaints about our lack of talent, and AlwaysOn aims to replace most of the functionality of all those different tools.
