One of the highlights of the Big Room floor at PDC 09 was an Azure IT PAC (Pre-assembled container), the unit of deployment within the Azure Data Centers. This particular model is the newest, Generation 4, and built to be deployed outside (versus the
indoor models used in the Chicago and San Antonio facilities). The unit on the PDC floor was (of course) a prototype - it's 20 feet long versus the 40-foot standard, and has more glass for viewing than a real unit would have. Regardless, it really made the
'cloud' seem that much more concrete for me!
