In February 2011, Vivek Kundra announced the “Cloud First” policy across the US Government. The directive, issued through the Office of Management and Budget, required agencies to give cloud technology first priority in developing IT projects. He also described cloud computing as a “10 year journey”. According to a Deltek report, federal agency spending on cloud computing will grow from $2.3 billion in fiscal 2013 to $6.1 billion by fiscal 2018. This forecast clearly raises the importance of understanding what has happened over the past few years.
