From the Document: "In September 2017, the Deputy Secretary of Defense issued a memorandum calling for the accelerated adoption of a Department of Defense (DOD) enterprise-wide cloud services solution as a fundamental component of ongoing DOD modernization efforts. As a component of this effort, DOD sought to acquire a cloud services solution accessible to the entirety of the Department that can support Unclassified, Secret, and Top Secret requirements, focusing on commercially available cloud service solutions, through the Joint Enterprise Defense Infrastructure (JEDI) Cloud acquisition program. As DOD carried out the acquisition process for the JEDI Cloud program, industry and Congress focused significant attention on DOD's intent to award the JEDI Cloud contract to a single company. On October 25, 2019, DOD announced it had awarded the JEDI Cloud contract to Microsoft."
