Dirty tricks surround bidding for Pentagon cloud-computing contract

A salacious dossier, a mystery client with an alias — they’re all part of the dirty-tricks campaigns unleashed over the last 10 months as some of the U.S.’ technology giants battle to win a $10 billion cloud-computing contract that the Pentagon plans to award to a single company, Bloomberg reports.Allegations of a corrupt procurement process have been directed at Pentagon officials and company managers, primarily at Amazon.com, the front-runner for the contract known as JEDI, which involves transitioning massive amounts of Defense Department data to a commercially operated cloud system. Microsoft, International Business Machines and Oracle are the biggest names jockeying against Amazon, though there’s no evidence they are behind the mudslinging.
