UNCLASSIFIED platform, ready to receive applications, data, or infrastructure for cloud deployment. The second set of activities is the ongoing work to migrate existing applications or to construct new applications onto the cloud platform. The migration activities will need to be overseen by an ongoing governance process that assures security, application development, and data and infrastructure standards. The fundamental activities required to stand up a cloud environment are composed offive lines of effort: 1. Technical Build - create network connectivity, encryption, data sourcing, and security 2. 3. 4. 5. services ( e.g., authentication and ongoing red team engagement) on an enduring basis. Governance - create stakeholder forums, policies, roadmaps, technical standards (architecture and application development), data connectivity standards, resiliency and failover standards, and migration approaches. Automated Provisioning and Billing - automate the ability to quickly provision cloud resources (storage, compute, and application development) and ensure cloud costs are appropriately captured to provide financial transparency. Migration Capability - create repeatable migration process, backed with qualified staff and playbooks for onboarding tenants. Workforce Development - identify, train, and engage resources to create a robust and sustainable cloud workforce. After the standup of the cloud environment and the conclusion of fundamental activities, the ongoing activities of migrating applications will take over. The magnitude of effort required to stand up a General Purpose cloud at the scale and complexity of the Department is initially best served through a single provider that will allow DoD to maximize pace and minimize risk. The effort required to migrate applications will vary greatly from system to system. Migrating to a cloud environment is not typically as simple as "lift and shift." The migration process will be defined in the DoD's Cloud Migration Playbook and will include the many different paths to realize cloud. The Department will closely monitor the initial efforts to migrate into the Department's General Purpose enterprise cloud. The lessons learned from the various migrations will inform the regular refinement of the playbook, which will provide a consistent and repeatable process for mission owners to apply to their respective systems and applications. Organizations within DoD that have previously implemented their own cloud will work with the Office of the DoD CIO to determine the best way to integrate their efforts with the Department's enterprise cloud strategy. Where it makes sense that a standalone cloud environment should be migrated to the Department's General Purpose cloud, a thoughtful migration approach will be developed that does not disrupt existing contracts. If it is determined that an existing standalone cloud should be retained, it will be given a formal Fit For Purpose designation and will be expected to adhere to the DoD's enterprise cloud policies. Governance and Organization Oversight and governance for the initial build out of this enterprise cloud strategy will be led by the Office of the DoD CIO. At some future date, once the General Purpose cloud environment is fully implemented and Fit For Purpose implementations have matured, it is possible that overall leadership could be transitioned to a different organization inside DoD. The DoD CIO will establish an enterprise cloud organization with appropriate leadership and the A-3
