Cloud Sovereignty as National Security Infrastructure
U.S. cloud sovereignty extends beyond compliance frameworks into the architecture of national security itself. The convergence of export controls, foreign investment review, supply chain security mandates, and semiconductor manufacturing policy creates a sovereign technology perimeter around American cloud infrastructure that has no parallel in any other jurisdiction. This report examines the national security instruments that shape U.S. sovereign cloud requirements — regulations that govern not merely how cloud services are delivered, but who can build them, what components they use, and which foreign entities are prohibited from accessing them.
Unlike the EU's regulatory approach (which primarily protects data from American access) or the UAE's mandate-driven model (which creates sovereign infrastructure for national development), the U.S. framework is explicitly designed to maintain technological supremacy while preventing adversary access to critical computing infrastructure. The Department of Commerce, Treasury, Defense, and State departments each enforce aspects of this perimeter through overlapping but distinct authorities. Understanding this architecture is essential for any organization operating in or supplying U.S. sovereign cloud infrastructure.
US cloud sovereignty is driven by three converging imperatives: protecting classified and controlled data from foreign intelligence services, ensuring continuity of government operations against state-sponsored cyberattack, and maintaining technological superiority through secure AI infrastructure. The CHIPS and Science Act ($52.7 billion), Executive Order 14028 (zero trust mandates), and the JWCC contract ($9 billion) together form the legislative-procurement-infrastructure triad underpinning American cloud sovereignty.
ITAR & Export Control Cloud Requirements
The International Traffic in Arms Regulations (ITAR), administered by the State Department's Directorate of Defense Trade Controls, restrict cloud workloads involving defense articles, technical data, and defense services to facilities and personnel subject to U.S. jurisdiction. Cloud service providers hosting ITAR-controlled data must ensure that only U.S. persons (citizens, permanent residents, or protected individuals) can access the data, that the infrastructure is physically located within the United States, and that no foreign national — even an allied nation's citizen — can access ITAR-controlled information without specific authorization.
AWS GovCloud was designed specifically to meet ITAR requirements with U.S. person-only access controls. Azure Government and Google Cloud's FedRAMP High environments similarly provide ITAR-compliant architectures. For defense contractors, ITAR cloud compliance is a prerequisite for participation in any program involving controlled technical data — covering everything from fighter aircraft schematics to satellite communication specifications. The practical impact is that the defense industrial base's cloud infrastructure must be separate from commercial cloud environments, creating a dedicated sovereign cloud market segment that cannot be served by standard commercial offerings.
ITAR-compliant cloud restricts all access to US persons and must be hosted within US territory. AWS GovCloud, Azure Government, and Google Government provide dedicated ITAR-compliant regions. The defense industrial base — from prime contractors like Lockheed Martin and RTX to thousands of sub-tier suppliers — must demonstrate ITAR cloud compliance for any controlled technical data, creating massive demand for certified sovereign infrastructure.

The Bureau of Industry and Security enforces export controls that increasingly intersect with cloud computing as AI models become dual-use technologies.
CHIPS Act: The $52.7 Billion Semiconductor Sovereignty Strategy
The CHIPS and Science Act allocates $52.7 billion for domestic semiconductor manufacturing, research, and workforce development. This investment directly supports cloud sovereignty by reducing U.S. dependence on foreign semiconductor fabrication — currently concentrated at TSMC in Taiwan, a geopolitically vulnerable supply chain chokepoint. Intel's planned fabs in Ohio, Arizona, and New Mexico, TSMC's Arizona facility, and Samsung's Texas expansion create domestic production capacity for the processors and accelerators that constitute cloud infrastructure. The Act's guardrails prohibit CHIPS recipients from significantly expanding semiconductor manufacturing in China for ten years, creating explicit supply chain separation between U.S. sovereign infrastructure and Chinese-connected manufacturing.
For cloud service providers, CHIPS Act implementation has two strategic implications. First, it will gradually increase the availability of domestically manufactured processors and AI accelerators, enabling "made in America" supply chain claims for sovereign cloud infrastructure. Second, the Act's research funding — including the National Semiconductor Technology Center — will accelerate next-generation chip designs optimized for AI workloads, improving the performance trajectory of sovereign cloud compute available to defense and intelligence customers.
The CHIPS Act's impact on sovereign cloud extends beyond fabrication. The act's guardrails prohibit recipients from expanding semiconductor manufacturing capacity in "countries of concern" (primarily China) for ten years, creating a de facto technology decoupling that reinforces sovereign supply chain architecture. For sovereign cloud providers, the CHIPS Act creates a timeline for domestic GPU and accelerator availability: TSMC's Arizona fab is expected to produce advanced-node chips by 2025-2026, Intel's Ohio fabs will follow, and Samsung's Taylor, Texas facility adds further domestic capacity. The sovereign cloud thesis strengthens as domestic semiconductor production comes online — enabling a "silicon-to-software" sovereignty stack that eliminates reliance on any foreign-controlled supply chain link. For defense procurement officials, this represents a fundamental shift from "best available" to "sovereign preferred" in infrastructure decision-making.
CFIUS: Foreign Investment Review in Cloud Infrastructure
The Committee on Foreign Investment in the United States (CFIUS) reviews foreign acquisitions and investments that could affect national security — including transactions involving cloud infrastructure, data centers, and AI compute companies. The Foreign Investment Risk Review Modernization Act (FIRRMA, 2018) expanded CFIUS jurisdiction to cover non-controlling investments in critical technology companies and real estate near military installations. For sovereign cloud, CFIUS creates a structural barrier preventing foreign adversary acquisition of or investment in U.S. cloud infrastructure providers. Notable CFIUS interventions include the forced divestiture of Grindr by its Chinese parent (data sensitivity), the blocked acquisition of MoneyGram by Ant Financial (financial data), and ongoing scrutiny of TikTok's data architecture.
CFIUS review now encompasses not just equity investments but also certain real estate transactions near military installations and sensitive government facilities — directly relevant to data center siting decisions for sovereign cloud infrastructure. The Committee's authority under FIRRMA (Foreign Investment Risk Review Modernization Act) allows review of non-controlling investments in "critical technology," "critical infrastructure," and "sensitive personal data" businesses — categories that encompass virtually every sovereign cloud provider. The practical implication is that any foreign investment in U.S. sovereign cloud companies faces potential CFIUS review, creating a barrier to foreign capital participation that reinforces domestic ownership of sovereign infrastructure. For global sovereign cloud investors, CFIUS risk must be evaluated in every U.S. market entry strategy, whether through equity investment, joint venture, or service partnership.
Foreign Adversary Risk & Entity Lists
The Bureau of Industry and Security (BIS) maintains the Entity List, Military End-User List, and Unverified List that restrict U.S. technology exports to designated foreign entities. In the cloud context, these lists prohibit the sale or provision of cloud services and computing resources to listed entities — including Chinese AI companies, Russian defense organizations, and other designated adversaries. BIS export controls on advanced semiconductors (October 2022, updated 2023 and 2024) restrict the sale of high-end GPU accelerators (NVIDIA A100, H100, and successors) to China, directly impacting the global distribution of sovereign AI compute capability and reinforcing U.S. technological advantage in classified and sovereign cloud performance.
The entity list framework extends to cloud services themselves. Commerce Department rules on Information and Communications Technology and Services (ICTS) authorize the Secretary of Commerce to prohibit or require mitigation of ICTS transactions posing unacceptable national security risks. This authority has been applied to specific Chinese cloud and AI companies and could be extended to any foreign cloud provider whose government exercises extraterritorial data access. For enterprise cloud architects, the entity list and ICTS review framework requires ongoing monitoring of supply chain composition — including subprocessors, CDN providers, and DNS services — to ensure no prohibited entities participate in the sovereign cloud delivery chain.
Supply Chain Security for Cloud Infrastructure
NIST's Cybersecurity Supply Chain Risk Management (C-SCRM) framework and Executive Order 14017 on America's Supply Chains establish comprehensive requirements for hardware provenance, firmware integrity, and software bill of materials (SBOM) in federal cloud infrastructure. Cloud providers serving defense and intelligence customers must maintain auditable supply chain documentation demonstrating that no adversary-manufactured or -compromised components exist within sovereign cloud infrastructure. The Secure Software Development Framework (SSDF) requires federal software suppliers — including cloud service providers — to attest to specific secure development practices, creating accountability for the entire software supply chain from source code through deployment.
NVIDIA GPUs powering classified AI workloads are designed in the US but manufactured by TSMC in Taiwan — a geographic concentration risk under Chinese military threat. TSMC's Arizona fabs (supported by CHIPS Act subsidies) and Intel's Ohio expansion aim to diversify fabrication, but new facilities won't reach volume production until 2027-2028. The CFIUS review process increasingly scrutinizes technology investments with cloud infrastructure implications, reflecting the sovereign supply chain imperative.
Executive Orders: The Cybersecurity Framework
Executive Order 14028 (Improving the Nation's Cybersecurity, 2021) established zero trust architecture requirements, software supply chain security standards, and enhanced logging requirements for federal cloud environments. Executive Order 14110 (Safe, Secure, and Trustworthy AI, 2023) imposed AI safety and security requirements that intersect with cloud sovereignty through data governance, model evaluation, and compute reporting requirements. Executive Order 14086 (Enhancing Safeguards for U.S. Signals Intelligence Activities, 2022) provides the surveillance reform framework underlying the EU-U.S. Data Privacy Framework. Together, these executive orders create an evolving compliance architecture that shapes sovereign cloud requirements across security, AI governance, and international data transfer dimensions.
The cumulative effect of these executive orders is a compliance architecture that mandates specific cloud security capabilities — zero trust, software supply chain attestation, enhanced logging, AI governance — as federal requirements rather than best practices. Cloud service providers serving the federal market must continuously adapt to this evolving framework, creating implementation costs that favor established FedRAMP-authorized providers over new entrants. For CISOs and compliance officers, executive order compliance is becoming as important as FedRAMP authorization itself — a cloud environment can be FedRAMP authorized but still non-compliant with specific executive order requirements, creating a layered compliance obligation that demands ongoing investment in security engineering and continuous monitoring.
Defense Industrial Base Cloud Requirements
The defense industrial base — over 300,000 companies — faces cloud sovereignty requirements through CMMC, DFARS (Defense Federal Acquisition Regulation Supplement), and NIST SP 800-171. CMMC Level 2 requires 110 security practices for Controlled Unclassified Information (CUI), while Level 3 requires 130+ practices assessable by government auditors. These requirements effectively mandate cloud environments with specific encryption, access control, audit logging, and incident response capabilities that standard commercial cloud cannot provide without significant customization. Cloud service providers including Microsoft GCC High, AWS GovCloud, and specialized CMMC-compliant managed service providers serve this market, creating a dedicated sovereignty tier for the defense supply chain.
Semiconductor Sovereignty & GPU Supply Chain
The sovereign cloud GPU supply chain intersects with geopolitical semiconductor competition. NVIDIA's advanced AI accelerators — the foundation of sovereign AI compute — are fabricated by TSMC in Taiwan, creating supply chain vulnerability that both the CHIPS Act and the Department of Defense are actively mitigating. The DoD's Trusted Foundry program ensures access to domestically manufactured semiconductors for classified applications. NVIDIA's development of lower-performance export-compliant GPUs for China demonstrates the bifurcation of the GPU supply chain along sovereignty lines — a trend that will accelerate as AI compute becomes a strategic national asset rather than a commodity. For investors, the semiconductor sovereignty thesis overlaps directly with sovereign cloud: organizations that control both the silicon and the software layers of AI compute hold the most defensible positions in the market.
Investment Implications
The national security dimension of U.S. sovereign cloud creates investment opportunities distinct from commercial cloud. Defense prime contractors (Lockheed Martin, RTX, Northrop Grumman) are increasingly building cloud-native capabilities for classified environments. Systems integrators (Booz Allen, Leidos, SAIC) hold the cleared workforce essential for sovereign cloud operations. Semiconductor companies (NVIDIA, Intel, AMD) benefit from both CHIPS Act subsidies and sovereign cloud compute demand. Defense-tech startups (Palantir, Anduril, Scale AI) build the AI applications that run on sovereign infrastructure. The cumulative investment opportunity spans the entire technology stack from silicon through infrastructure to application.
Strategic Outlook 2026–2030
U.S. cloud sovereignty regulation will tighten through 2030 as great power competition intensifies. Export controls will expand to cover additional AI model architectures and training techniques. CFIUS review will extend to cloud service agreements, not just equity investments. CMMC enforcement will mature, creating real consequences for non-compliant defense suppliers. And the CHIPS Act manufacturing buildout will begin producing domestically fabricated processors and accelerators, gradually enabling "end-to-end sovereign" cloud infrastructure from silicon to software. The combined market for national security-driven sovereign cloud — spanning defense, intelligence, export-controlled industries, and critical infrastructure — will exceed $200 billion by 2033, representing the single largest sovereign technology market on earth.
The CHIPS Act: Reshoring the Sovereign Compute Supply Chain
The CHIPS and Science Act, signed in 2022 with $52.7 billion in semiconductor manufacturing incentives, represents the most significant U.S. government intervention in technology supply chains since the Cold War. For sovereign cloud infrastructure, the CHIPS Act addresses a critical vulnerability: the dependency on Taiwan Semiconductor Manufacturing Company (TSMC) for the advanced chips powering AI workloads in classified and government cloud environments.
TSMC's Arizona fabrication facility (expected to produce 3nm and 4nm chips), Samsung's Texas expansion, and Intel's Ohio and Arizona mega-fabs are all partially funded by CHIPS Act subsidies. For sovereign cloud, the strategic significance is that U.S.-fabricated chips create a trusted supply chain for government and defense cloud infrastructure — reducing the risk that geopolitical disruption in the Taiwan Strait could cut off the supply of advanced processors to American data centers processing classified and government workloads.
The intersection of CHIPS Act and sovereign cloud creates investment opportunities in domestic semiconductor manufacturing, advanced packaging and testing facilities, and the specialized cooling and power infrastructure required for next-generation chip fabrication. For defense contractors and cleared cloud providers, the ability to demonstrate an end-to-end domestic supply chain — from chip fabrication through server assembly to data center deployment — is becoming a competitive differentiator in classified cloud procurement.
The CHIPS Act provides $52.7 billion for domestic semiconductor fabrication. TSMC's Arizona fabs and Intel's Ohio expansion aim to reduce dependency on Taiwanese manufacturing — critical given that NVIDIA GPUs powering classified AI workloads are currently fabricated exclusively in Taiwan under Chinese military threat.
ITAR-Compliant Cloud: The $150 Billion Defense Export Enabler
International Traffic in Arms Regulations (ITAR) impose strict controls on the export and transfer of defense articles and technical data. Cloud infrastructure hosting ITAR-controlled data must be physically located in the United States, operated exclusively by U.S. persons, and logically isolated from non-U.S. access. AWS GovCloud and Azure Government are the primary ITAR-compliant cloud platforms, but the compliance requirement extends beyond hosting — it encompasses the entire data lifecycle including processing, storage, backup, and disaster recovery.
The U.S. defense export market exceeded $150 billion in authorized agreements in recent years, and the technical data underlying these exports increasingly resides in cloud environments. Defense contractors managing ITAR data face a compliance decision that directly maps to sovereign cloud: use an ITAR-compliant sovereign cloud platform, or risk violations carrying criminal penalties including imprisonment and fines up to $1 million per violation. This compliance mandate creates non-discretionary demand for U.S. sovereign cloud from every company in the defense industrial base.
Cybersecurity Maturity Model Certification (CMMC) compounds the requirement. CMMC Level 2, which will be required for all DoD contractors handling Controlled Unclassified Information (CUI), mandates 110 security controls derived from NIST SP 800-171. CMMC Level 3 adds additional controls for the most sensitive CUI. Sovereign cloud platforms that provide inherent CMMC compliance reduce the compliance burden on defense contractors — creating a powerful procurement incentive to consolidate workloads on pre-certified sovereign infrastructure.
ITAR-compliant cloud restricts access to US persons only with US-territory hosting. AWS GovCloud, Azure Government, and Google Government provide dedicated regions. The defense industrial base — from Lockheed Martin and RTX to thousands of sub-tier suppliers — must demonstrate compliance for controlled technical data.
CFIUS & Foreign Adversary Risk in Cloud Infrastructure
The Committee on Foreign Investment in the United States (CFIUS) increasingly scrutinizes cloud infrastructure transactions involving foreign ownership, control, or influence. Executive orders targeting "countries of concern" — primarily China, Russia, Iran, and North Korea — restrict the use of cloud infrastructure with connections to foreign adversary entities for processing sensitive U.S. data. The Commerce Department's Bureau of Industry and Security (BIS) proposed rules in January 2025 requiring Infrastructure-as-a-Service providers to verify the identity of foreign users and report transactions involving training large AI models.
These foreign adversary risk provisions create structural demand for U.S.-sovereign cloud that is demonstrably free from foreign ownership, foreign personnel access, and foreign supply chain dependencies. For cloud providers seeking government contracts, the ability to certify a complete absence of foreign adversary risk across the technology stack — from silicon fabrication through software deployment — is becoming as important as traditional security accreditations.
The practical impact extends to the venture capital and private equity markets. Cloud infrastructure companies seeking U.S. government contracts must carefully structure their capitalization tables to avoid CFIUS-triggering foreign investments. Several promising cloud startups have been forced to restructure or divest foreign investments to maintain government market eligibility. This dynamic creates a two-tier market where U.S.-sovereign cloud companies with clean ownership structures command premium valuations for government-facing business lines.
Critical Infrastructure Protection & Cloud Sovereignty
CISA's designation of cloud computing as critical infrastructure elevates sovereign cloud from a procurement preference to a national security imperative. The 16 critical infrastructure sectors identified under Presidential Policy Directive 21 — including energy, financial services, healthcare, communications, and defense — increasingly depend on cloud infrastructure for operational continuity. When that cloud infrastructure is controlled by foreign entities or subject to foreign legal jurisdiction, it introduces systemic risk to national critical infrastructure.
Executive Order 14028 (Improving the Nation's Cybersecurity) and the subsequent DoD Zero Trust Reference Architecture mandate that federal agencies implement zero trust security across all information systems, including cloud deployments. For sovereign cloud providers, zero trust is not an optional security enhancement — it is an architectural requirement for any platform seeking federal government customers. The intersection of zero trust mandates, critical infrastructure protection requirements, and supply chain security provisions creates a compliance environment that structurally favors U.S.-sovereign cloud providers with end-to-end security accreditation.
Strategic Outlook: U.S. Cloud Sovereignty as National Policy
The trajectory of U.S. cloud sovereignty policy is toward increasing stringency across every dimension — supply chain security, foreign adversary risk, data localization, and AI governance. The convergence of the CHIPS Act (reshoring semiconductor manufacturing), CFIUS expansion (restricting foreign influence in technology infrastructure), CMMC implementation (mandating cybersecurity maturity for defense contractors), and zero trust mandates (requiring continuous verification across all systems) creates a regulatory environment where U.S. sovereign cloud is the path of least compliance resistance for any organization touching federal data.
For enterprises operating in the U.S. defense, intelligence, and federal civilian markets, sovereign cloud adoption is an immediate strategic requirement — not a future planning consideration. The infrastructure is operational, the compliance frameworks are established, and the procurement vehicles (FedRAMP Marketplace, JWCC, C2E, StateRAMP) provide clear pathways to market. The question for market participants is not whether U.S. cloud sovereignty requirements will intensify — they will — but whether they are positioned to capture the value this intensification creates.
The NSA's $10 billion WildandStormy contract with AWS modernizes its Hybrid Compute Initiative. Deltek projects federal cloud spending exceeding $30 billion by 2028. JWCC Next — the successor contract — will expand classified cloud procurement beyond the four current hyperscalers to include entire ecosystems and specialized vendors.
The CLOUD Act & Extraterritorial Jurisdiction
The Clarifying Lawful Overseas Use of Data (CLOUD) Act of 2018 authorizes U.S. law enforcement to compel American technology companies to provide stored data regardless of where that data is physically located. This extraterritorial reach is the single most cited driver of sovereign cloud adoption outside the United States — and paradoxically, it also shapes the U.S. domestic sovereign cloud market by creating a legal framework that foreign governments cite when demanding data localization within their own borders.
For U.S. sovereign cloud providers serving domestic government and defense customers, the CLOUD Act creates a compliance asymmetry: the same legal authority that gives U.S. agencies access to data on American cloud infrastructure is the precise authority that European, Middle Eastern, and Asian governments are building sovereign clouds to counter. Congress has authorized executive agreements under the CLOUD Act with qualifying foreign governments (the UK agreement is operational), but broader adoption remains limited. For cloud procurement officers in ITAR-controlled industries, the CLOUD Act's domestic implications are less problematic — U.S. government access to U.S. defense data is generally expected — but the international backlash creates market fragmentation that affects multinational defense supply chains operating across jurisdictions.
The strategic implication for U.S. sovereign cloud policy is a trade-off between surveillance capability and global cloud market share. As more nations build sovereign infrastructure explicitly to avoid CLOUD Act exposure, American hyperscalers lose market access in government and regulated sectors. The EU-U.S. Data Privacy Framework, built partly on Executive Order 14086's surveillance reform commitments, represents an attempt to bridge this gap — but its durability under changing administrations remains uncertain, and the European Court of Justice's track record of invalidating transatlantic data transfer agreements (Safe Harbor, Privacy Shield) suggests structural legal instability.
The CLOUD Act cuts both ways for US sovereignty: it enables US law enforcement to compel data production from US-headquartered providers regardless of storage location (strengthening domestic intelligence capabilities), but simultaneously drives European and Asian customers toward non-US providers (creating commercial headwinds for American hyperscalers). This tension is most visible in the EUCS debate, where proposed sovereignty requirements would effectively exclude US providers from the highest EU certification levels.
FedRAMP & Government Cloud Authorization
The Federal Risk and Authorization Management Program (FedRAMP) provides the authorization framework for cloud service providers serving U.S. federal agencies. FedRAMP High baseline requires implementation of 421 security controls based on NIST SP 800-53, with continuous monitoring and annual assessment. As of 2025, over 350 cloud service offerings hold FedRAMP authorization, but the vast majority are authorized at the Moderate baseline — FedRAMP High authorizations remain concentrated among a relatively small number of established providers.
The FedRAMP authorization process typically requires 12-18 months and $2-5 million in assessment costs, creating a significant barrier to entry for new sovereign cloud providers. The GSA-managed FedRAMP Program Management Office has undertaken process reform to accelerate authorizations, but the fundamental security assessment requirements remain rigorous. For DoD workloads, the Defense Information Systems Agency (DISA) manages additional Impact Level (IL) requirements: IL4 and IL5 for Controlled Unclassified Information, IL6 for Secret-classified data, all requiring progressively stricter controls and isolation.
For enterprise and government procurement officers, FedRAMP authorization is the minimum threshold for sovereign cloud consideration — but authorization alone is insufficient. The specific Impact Level, continuous monitoring posture, personnel clearance levels, and encryption architecture must all align with the data classification and regulatory requirements of each workload. Cloud providers that maintain multiple authorization levels (FedRAMP High + IL4 + IL5) and demonstrate operational maturity through years of continuous monitoring hold decisive competitive advantage over newly authorized providers.
Zero Trust Architecture for Federal Cloud
The White House's National Cybersecurity Strategy and OMB Memorandum M-22-09 mandate federal agencies to achieve specific zero trust maturity goals. For sovereign cloud environments, zero trust implementation requires continuous identity verification (moving beyond perimeter-based security), microsegmentation of network traffic (preventing lateral movement within cloud environments), device trust assessment (ensuring only authorized endpoints access sovereign resources), and application-layer security (encrypting data in transit and at rest with government-controlled keys).
CISA's Zero Trust Maturity Model provides the reference framework, defining progression from Traditional through Advanced to Optimal maturity across identity, device, network, application/workload, and data pillars. Cloud providers serving federal agencies must demonstrate how their infrastructure supports zero trust architecture — not merely as an optional feature but as an embedded capability. The intersection of zero trust and sovereign cloud creates a technical moat: providers that can demonstrate zero trust architecture within FedRAMP High or DoD IL5 environments possess compound credentials that competitors cannot quickly replicate.
