When the Microsoft CEO publicly declared “We're all in” on cloud computing in March 2010, he wasn't just referring to Microsoft products and platforms. He also was giving the IT organization a mandate to move to the cloud. Today, Microsoft IT has deployed more than 50 applications on Windows Azure, manages more than 40,000 email boxes and 18,000 personal Microsoft SharePoint sites on Microsoft Office 365, and is expanding the number of employees who are using Microsoft Dynamics CRM Online. Overall, we expect 80 percent of Microsoft line-of-business applications to be cloud-based by 2016.
