I'm a geekette who enjoys playing with new technology for software developers. I work as a Developer Evangelist for Microsoft. My current focus is on Windows Store development for Windows 8.
Today, during the opening keynote of the Professional Developers Conference (PDC), Ray Ozzie announced Windows Azure. Windows Azure is an operating system for the cloud. You may have also heard it called by its codename "Red Dog".
Windows Azure provides the same facilities that a desktop OS provides, but on a set of connected servers ("the cloud").
