Cloud computing became a hot topic in mid-2008 and, by mid-2009, had achieved top buzzword status. As proof of its popularity, a mid-August 2009 search on Bing.com for ‘‘cloud computing’’ returned 92 million hits. Hardly a week goes by that doesn’t include at least one cloud computing conference somewhere around the globe. Mainstream business magazines, such as Forbes and Business Week, regularly run cloud-computing feature articles and comprehensive special reports, such as Business Week’s ‘‘Cloud Computing’s Big Bang for Business’’ of June 5, 2009, which presented case studies of cloud usage by Serena Software, Optum Health, Genentech, Coca-Cola Enterprises, and Info Tech (http://bit.ly/uecfb, www.businessweek.com/magazine/toc/09_24/B4135cloud_computing.htm). Earlier that week, Microsoft CEO Ray Ozzie addressed Silicon Valley’s Churchill Club on ‘‘The Potential of Cloud Computing’’ (http://bit.ly/g2wqn, www.churchillclub.org/eventDetail.jsp? EVT_ID=820).
