We have a number of tools that we’ve developed for SQL Server available as free downloads.
Availability Group Demonstrator
This is the application we use to demonstrate the features of Availability Groups in SQL Server 2012 at conferences and during our Immersion Events. The application provides a multi-document interface that allows multiple connections with different configurations for read-only and/or read-write workloads to demonstrate the connection failover, read-only routing, and multi-subnet failover features of Availability Groups in SQL Server 2012.
SQL Server 2012 Extended Events Add-in
This add-in for SQL Server 2012 Management Studio adds backwards compatibility UI support for SQL Server 2008 and SQL Server 2008R2 instances for managing Extended Events.
SQL Server 2012 Availability Group Add-in
This add-in for SQL Server 2012 Management Studio adds a new menu for Availability Groups to synchronized uncontained objects across the replica servers. The current release includes the ability to synchronize user-defined server roles and their permissions, logins and their permissions, and SQL Agent jobs and schedules using a SQLCMD mode script.
