Microsoft to Share Some IE9 Details at PDC

That's the company's message Tuesday from its Professional Developers Conference here, where Chief Software Architect Ray Ozzie gave the opening keynote address.

Ozzie announced plans for the formal launch of Windows Azure, the cloud-based operating system that lets developers write programs that run on servers in Microsoft's data centers. It will be in production for all users starting January 1, though a few customers will enter production now, Ozzie said.

In other news, Microsoft announced a technology preview of a new data service, code-named Dallas, that lets Azure customers access various commercial and public data sets. Early partners include NASA, the Associated Press, and InfoUSA.
