Here I am at PDC, Los Angeles Convention Centre and Ray Ozzie, Chief Software Architect, Microsoft, just announced that the new Windows on the Cloud named as Windows Azure. Windows Azure is the windows on cloud which offers additional services such as Live Services, SharePoint Services, SQL Services (Formerly SSDS) and a few other services offering a complete cloud platform.
Windows Azure is a services platform for development, application hosting & service management on the cloud that businesses can leverage.
