IBM has followed Oracle in filing a bid protest against the Pentagon's'single-cloud' requirements for its JEDI contract, which could be worth up to $10bn over 10 years. The cloud is disrupting traditional operating models for IT departments and entire organizations. The company filed the bid protest with the Government Accountability Office just ahead of this Friday's deadline for vendors to submit JEDI, or Joint Enterprise Defense Infrastructure, proposals. IBM is contesting the single-vendor requirement and argues that some requests favor a single vendor. "JEDI's primary flaw lies in mandating a single cloud environment for up to 10 years," Sam Gordy, IBM's US Federal general manager, said in a blogpost.
