According to Matt (WordPress Creator) from http://publisherblog.automattic.com/2009/11/19/wordpress-and-windows-azure/ http://publisherblog.automattic.com/2009/11/19/wordpress-and... "What did you announce about WordPress at Microsoft PDC 09? As part of the introduction of the Windows Azure platform, we announced that self-hosted WordPress can be run in an Azure environment on an open source stack of Apache, MySQL, and PHP. Showing MySQL in particular at a Microsoft conference was unusual. Are you moving WordPress.com to Azure? No. WordPress.com, which is Automattic’s hosted blogging service, is going to stay on its existing infrastructure. Martin Cron from the Cheezburger Network launched a new blog Oddly Specific on Azure, which some people confused with Automattic. Do you use Azure at all? Yes, we’ve been testing out their blob storage as an alternative to Amazon S3 and Rackspace Cloudfiles. We don’t currently use it in production."
