DoD Cloud Computing: Private Cloud Model and NIST Characteristics
This paper examines the Department of Defense's adoption of cloud computing technology, focusing on how its enterprise cloud infrastructure aligns with federal IT efficiency goals and security requirements. It discusses the roles of key frameworks — including FedRAMP, the Cloud Computing Security Requirements Guide (CC SRG), and DISA's Cloud Security Model — in governing DoD cloud services. The paper also applies NIST's cloud computing definition to classify the DoD's deployment model as private and analyzes how the department maps to NIST's essential cloud characteristics, including resource pooling, measured service, and rapid elasticity.

What makes this paper effective
- Grounds its analysis in authoritative primary sources — the DISA Cloud Computing Security Requirements Guide and the NIST Special Publication 800-145 — lending credibility to its claims.
- Directly answers specific analytical questions (Is the DoD cloud private, public, or hybrid? How does it map to NIST characteristics?) before elaborating, giving the paper a clear Q&A structure.
- Accurately applies NIST's formal taxonomy to a real-world government deployment, demonstrating applied understanding of cloud computing frameworks.
Key academic technique demonstrated
The paper demonstrates applied concept mapping — taking an established theoretical framework (NIST's essential characteristics of cloud computing) and systematically matching it against a concrete institutional case (the DoD). This technique is common in technology policy and information systems writing, where students must bridge definitional standards and real-world implementations.
Structure breakdown
The paper opens with a general overview of how cloud computing supports DoD-wide IT efficiency and security goals. It then introduces the key regulatory frameworks (FedRAMP, CC SRG, DISA CSM) governing cloud adoption. Two focused analytical sections follow: one classifying the DoD's model as a private cloud under NIST definitions, and another mapping the department's infrastructure to NIST's five essential cloud characteristics. The bibliography cites two primary sources throughout.
Introduction to DoD Cloud Computing
Through cloud computing services and technology, the Department of Defense (DoD) is able to establish an enterprise cloud that aligns with department-wide, federal-level IT efficiency programs and plans. Cloud computing facilitates the consolidation of infrastructure, leveraging of commodity information technology services, and elimination of operational redundancies, while simultaneously boosting operational continuity. The success of these programs, on the whole, depends on well-implemented security requirements that are clearly defined and understood by DoD Components as well as industry. Consistent application and enforcement of these requirements guarantees mission execution, protects sensitive information, enhances mission success, and ultimately leads to the operational efficiencies and outcomes sought by the DoD (DISA, 2016).
Security Frameworks Governing DoD Cloud Services
A memo by the Defense Department's Chief Information Officer, dated December 15, 2014, regarding updated guidance on acquiring and using commercial cloud computing services, defines the responsibilities of DoD Components when utilizing enterprise cloud services. This memo enables responsible, minimal acquisition of cloud services by components, in accordance with security requirements outlined in FedRAMP (Federal Risk and Authorization Management Program) and the CC SRG (Cloud Computing Security Requirements Guide).
Previously, the Defense Information Systems Agency (DISA) presented concepts for operating in the business cloud through its Cloud Security Model (CSM). The first version of the CSM described the general framework and offered early guidance on public data. A subsequent version (v. 2.1) also incorporated the subject of Controlled Unclassified Information. The CC SRG covers cloud security conditions in a format consistent with other DISA-issued SRGs. This particular SRG covers, displaces, and repeals the earlier CSM (DISA, 2016).
DoD Cloud Deployment: Private Model Under NIST
Based on NIST definitions, the DoD's cloud is classified as a private cloud, with services offered exclusively for the department. It supports a number of department-sponsored tenants within a single cloud environment. The DoD retains final authority over cloud service usage, and all non-DoD service utilization must be DoD-sanctioned and DoD-sponsored. Resources providing cloud services must be reserved for the department's use and must be physically separated from resources not reserved for the DoD.
Defense Department business service programs classified as SaaS cloud services — such as DCO (Defense Connect Online), DEE (Defense Enterprise Email), and DEPS (DoD Enterprise Portal Service) — must also comply with DoDI 8510.01 prerequisites. These programs are not required to be assessed through FedRAMP, nor do they share department ATOs (authorizations to operate) with FedRAMP's secure store (DISA, 2016).
Conclusion
The DoD's cloud infrastructure reflects a deliberate, security-driven application of the NIST private cloud model, supported by layered policy frameworks — including FedRAMP, the CC SRG, and DISA's oversight — that together ensure operational continuity and mission security. By mapping closely to NIST's essential characteristics of cloud computing, the department demonstrates a structured and policy-compliant approach to enterprise IT modernization.
