US major tech company 0'>Amazon is challenging the recent Pentagon's decision to grant a $10bn (£7.8bn, €9.1bn cloud contract to 0'>Microsoft, according to Reuters.

The formal notice of the challenge was filed on November 8. Amazon is not satisfied with the fact that Pentagon's decision was reportedly based on direct orders from the US President.

According to Guy Snodgrass, former Pentagon' speechwriter, a call took place in summer 2018 between Presiden Trump and the then US secretary of defence James Mattis. During the call, Trump urged Mattis to "screw Amazon" out of the contest, Snodgrass alleges.

Andy Jassy, CEO of Amazon Web Services, claimed that the US agency was unable to grant a contract objectively as the president was disparaging one of the participants.

Amazon believes that the contest related to the Joint Enterprise Defense Infrastructure Cloud (JEDI) contract was marked by "deficiencies, errors, and unmistakable bias".

Pentagon granted the $10bn JEDI contract to Microsoft in late October of this year. The JEDI is set to make the Pentagon more up-to-date in terms of technology, with one of its key goals is to make data from battlefields and remote locations more accessible.

IBM and Oracle also participated in the bid, however,they were eliminated from the competition.
