Windows Azure was in the news again when Microsoft announced the “Windows Azure Platform Appliance” at their Worldwide Partner Conference (WPC) on July 12th. It consists of pre-configured containers that hold between a hundred and a thousand servers running the Windows Azure platform. These containers will initially be housed at Dell’s, HP’s and Fujitsu’s datacenters. Microsoft is hoping that large enterprise customers, like eBay, will later host these containers at their own datacenters on site. But what is Windows Azure? and does it have anything to do with Webhosting?
