It's been four and a half years since the White House proclaimed it wanted agencies to make a big move to cloud computing via the so-called "cloud first" policy. But the pace of cloud adoption has been far slower than what former federal CIO Vivek Kundra probably had in mind back in 2010. The American Council of Technology-Industry Advisory Council set out to find out why -- and then, in a new guidebook, explain how agencies can break down perceived barriers to cloud adoption. Mark Day is the co-chair of the ACT-IAC Cloud Computing Working Group and also the deputy assistant commissioner in GSA's integrated technology service. He tells In Depth guest host Jared Serbu what's in the new guidebook and how it will help agencies move to the cloud.
