I get a lot of inquiries in my travels and communications about additional resources to learn more about Microsoft SQL Server. Well here are 2 very good resources for you to be able to obtain Virtual Labs.

Try Microsoft SQL Server in a virtual lab and learn more about AlwaysOn, ColumnStore Index, PowerView, and other new features. Virtual labs are simple, with no complex setup or installation required.
You get a downloadable manual and a 90-minute block of time for each module. You can sign up for additional 90-minute blocks at any time.
