Every new software released is met with skepticism. What is it about SQL Server 2012 that makes it so special? SQL Server 2012 is intent on revolutionizing the perception of recovery and availability. Presently, these concepts, recovery and availability, are viewed as individual databases (mirroring, replication, log shipping) or failover clustering which is a whole SQL Server instance. SQL Server 2012 been designed to handle a collection of databases as a unit; this is with the enhancement of Failover Clustering. Dealing with databases as a group, other than individually, is called Availability Group. This is required for today’s multi-database and complex applications. Availably Group permits a group of Databases to fail over as a single unit. If there is a failure a single instance SQL server has the flexibility to fail over availability group to instance C, another availability group to instance D, and it goes on.
