SQL Server 2012-2014 AlwaysOn Availability Group Series

This article will present the SQL Server 2012-2014 AlwaysOn Availability Group feature and describe how-to implement a virtualized AlwaysOn Cluster with four WS2012 R2 Core nodes and four Availability Groups. I will post later articles about Administration, Troubleshooting and Monitoring.

AlwaysOn Availability Groups DesignAll nodes will be Virtualized on Hyper-V 2012 R2

For the demonstration of AlwaysOn Availability Groups capabilities, the Cluster will be configured with four Availability Groups dispatch on four nodes (with this configuration, all SQL instances can be active at the same time, the workload is balanced and the environment supports the loss of one datacenter)
