Amazon snagged a win in its ongoing battle for the Pentagon's Joint Enterprise Defense Infrastructure (JEDI) cloud contract, as a federal judge ordered Microsoft to cease work on the $10 billion project.

A spokesperson for Amazon said it was common practice to stay contract performance while a protest is pending. "It's important that the numerous evaluation errors and blatant political interference that impact the JEDI award decision be reviewed," the spokesperson wrote.

Amazon filed suit back in November challenging the Pentagon's decision after Microsoft was awarded the highly contested contract about a month earlier.

The 10-year, $10 billion contract seeks to move approximately 80% of all Department of Defense (DoD) data off premises and into a single cloud.

From the start, the contract has been mired in controversy, and that controversy is now at the heart of Amazon's lawsuit in which rival Microsoft is now entangled.

“AWS is uniquely experienced and qualified to provide the critical technology the U.S. military needs and remains committed to supporting the DoD’s modernization efforts,” the spokesperson said in an email following Amazon's filing. “We also believe it’s critical for our country that the government and its elected leaders administer procurements objectively and in a manner that is free from political influence. Numerous aspects of the JEDI evaluation process contained clear deficiencies, errors, and unmistakable bias — and it’s important that these matters be examined and rectified.”

Specific details of what Amazon is alleging remains unclear, largely as a result of a protective order granted to conceal proprietary information that may come up throughout the suit.

What is known is Amazon's case will likely center around President Donald Trump and DoD CIO Dana Deasy, both of whom are cited in a notice describing several video clips submitted into to evidence late last year.

Trump has been at the center of a highly public feud with Amazon CEO Jeff Bezos, who also owns the Washington Post.

AWS CEO Andy Jassy shed some light on the issue during the company's AWS re:Invent show in December during a press conference when he implied that Amazon — not Microsoft — should have won the lucrative government contract.

"We feel pretty strongly that it was no adjudicated fairly," he said at the time. “If you do a truly objective and detailed apples-to-apples comparison of the platforms, you don’t end up in the spot where that decision was made."

Meanwhile, Microsoft has, until Thursday's roadblock, reportedly been hard at work on fulfilling its contract obligations. In an interview with CNBC Microsoft President Brad Smith said, "we have if anything been moving even faster since that contract was awarded."

For now, at least, it seems Amazon has successfully stalled Microsoft's efforts.
