According to a recent post by James Staten Vice President and Principal Analyst at Forrester Research

“With the latest release of Windows Azure here at Build, Microsoft’s premier developer shindig, this cloud service has become a serious contender for the top spot in cloud platforms.”

“If you have been waiting for your peers to use Windows Azure, that excuse is going away too. Microsoft said it now has over 100,000 separate named accounts using Azure, is adding thousands per month, and compute use is doubling every six months. If you are a government agency, an airline, a pharmaceutical maker, media company, a software-as-a-service (SaaS) provider, an oil company, or a financial services firm, your peers are already using Windows Azure. And our surveys of developers, development managers, and even I&O pros show Microsoft as a top-five most used cloud platform.”
