Earlier this week, a judge for the U.S. Court of Federal Claims has ruled that Amazon can immediately resume work on the project. That's a contract worth up to $600 million over 10 years, Federal Computer Week's Frank Konkel reports.

"We are pleased with the Court’s decision and look forward to resuming our work on this important contract with our customer," an Amazon spokesperson told Business Insider.

This is Amazon's first-ever "private" cloud and a real game changer in a fledgling market that's already generating about $131 billion this year and growing 47%, market research firm Gartner says.
