The October 2012 update of the Windows Azure Training Kit includes 47 hands-on labs, 24 demos and 38 presentations designed to help you learn how to build applications that use Windows Azure services. This technical content covers several of the new Windows Azure features including Windows Azure Web Sites, Virtual Machines, the new Management Portal, and new SDK and tools. The October update includes updated hands-on labs to use the latest version of Visual Studio 2012 and Windows 8, new demos and presentations.
The training kit (available for download here) is the most authoritative learning resource on Windows Azure. I highly recommend that you download the training kit, review the presentations and go through the HOLs.
