UNCLASSIFIED The implementation of General Purpose cloud needs to comprehend four key tenets: • • ��� • Offer Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) Offer separate environments at all classification levels Centralized computing to tactical edge computing for the warfighter Enable emerging technologies, such as AI The JEDI Cloud Program will be the foundational approach to deliver the benefits of a General Purpose enterprise cloud for DoD while embracing the four tenets above. The setup of and migration to the JEDI Cloud requires the steps outlined in the Migration section. A key implementation imperative is that mission owners will be able to rapidly onboard and control their environments, but with common implementation governance supported by a contract. Fit-for-Purpose In situations where a General Purpose cloud solution is not capable of supporting mission needs, the Department may use a Fit For Purpose commercial solution or an on-premises cloud solution. Two examples are described here: 1. Software as a Service (SaaS): DoD software applications (e.g., email, chat, collaboration, etc.) over time will migrate to a subscription service where an indusµ-y partner will be leveraged for both applications and infrastructure. 2. The Department's milCloud 2.0 environment, a cloud-services product portfolio managed by the Defense Information Systems Agency (DISA), features an integrated suite of capabilities designed to drive agility into the development, deployment, and maintenance of secure DoD applications. The primary implementation bias for DoD will be to utilize General Purpose cloud computing. Only when mission needs cannot be supported by General Purpose will Fit For Purpose alternatives be explored. In such a case, a mission owner will be required to submit for approval an Exception Brief to the Office of the DoD CIO describing the capability and why the General Purpose cloud service does not support their mission. As Fit For Purpose solutions are justified, approved, and established, each Fit For Purpose cloud environment will be enacted with enterprise capabilities and scalability in mind. They should stiII support networking with the General Purpose cloud environment as well as with other Fit For Purpose solutions through modern commercial cloud capabilities for both inter-cloud and cross­ domain communication. Secure network peering will allow for data sharing and increased visibility where required. The Department recognizes that the commercial cloud marketplace will continue to evolve. DoD expects that cloud technology and offerings will continue to become more interoperable and seamlessly integrated, enabling lower transaction costs and better inter-cloud security features across multiple providers. DoD is best served by a robust, competitive, and innovative technology industrial base. Cloud Migration There are two fundamental types of work that must be considered in any cloud implementation. The first is a set of fundamental activities that are required to stand up a cloud A-2
