Thirteen European Cloud Providers Rally Behind EU's Tech Sovereignty Package to Curb US Cloud Dominance

The Core Anxiety: Why the US CLOUD Act Makes Sovereignty Washing Unsustainable

The primary legal fissure driving the EU's urgency is not a European law but an American one. The US CLOUD Act (Clarifying Lawful Overseas Use of Data Act) of 2018 allows American law enforcement to compel any US-headquartered company to produce data it holds—regardless of where in the world that data is physically stored . This creates a fundamental paradox for European governments. Even if hyperscalers like Amazon, Microsoft, or Google store EU public-sector data on servers in Frankfurt or Paris through a European subsidiary, the data remains legally accessible to US authorities.

Analysts have labeled this a "sovereignty washing" problem: marketing that promises data localization cannot override the extraterritorial reach of US law . This legal reality has been further compounded by security incidents that eroded trust, such as when CISA's own cloud encryption keys were exposed months prior . The result is a consensus among EU policymakers that only a provider not subject to the CLOUD Act's reach can offer genuine technical sovereignty.

Deconstructing the Tech Sovereignty Package

The package, formally presented on May 27 after months of delays, bundles four main initiatives designed to create what officials call an integrated "European technology stack" .

Cloud and AI Development Act (CADA)

CADA is the legislative centerpiece. It aims to at least triple the EU's data center capacity within five to seven years and, critically, will legally define what a "sovereign cloud" means for the first time in EU law . It establishes a single EU-wide cloud policy for public administrations and procurement. A leaked draft reveals it will propose strict criteria for "highly critical" state tenders that are designed to exclude Amazon Web Services, Microsoft Azure, and Google Cloud from sensitive projects .

Chips Act 2.0

This marks a strategic pivot from the first Chips Act's focus on building supply capacity to now stimulating demand for European-made semiconductors, especially for AI applications . The new framework includes demand aggregation mechanisms and crisis-management tools. Most aggressively, it contains provisions that would let Brussels force chipmakers to prioritize EU orders over existing private supply agreements during a crisis .

Open Source Software Strategy and Energy Roadmap

The package is rounded out by a dedicated strategy to promote European open-source digital ecosystems as alternatives to proprietary US software, and a sector-specific strategic roadmap for AI adoption in the energy sector .

How the Rules Would Reshape Public-Sector Cloud Contracts

The most tangible impact will be felt in government IT procurement across all 27 member states. The proposals would categorically restrict the use of US cloud platforms for processing sensitive public-sector data .

• Targeted Sectors: Healthcare records, financial systems, and judicial data are explicitly named .
• Mechanism of Restriction: The restrictions are not an outright commercial ban. Instead, CADA creates a de facto "Buy European by Design" approach via certification and procurement rules that US firms would struggle to satisfy, effectively pushing them out of the highest-value government contracts .
• The Immediate Effect: EU governments would be forced to migrate these sensitive workloads to European providers like OVHCloud, Scaleway, or STACKIT, a process already piloted by the €180 million Commission contract .

The Immovable Challenges to a Swift Decoupling

Despite the regulatory momentum, analysts highlight profound structural barriers that will make reducing dependence a drawn-out and expensive process.

The CLOUD Act Paradox Persists. Even a successful migration to a fully European cloud provider does not grant absolute immunity from the CLOUD Act. If a US company is involved anywhere in the provider's supply chain, the data could still be in legal peril, creating a persistent and difficult-to-close vulnerability .

Economic Gravity and Market Concentration. Nearly 70% of Europe's cloud market is controlled by the three US hyperscalers . European enterprises and governments are deeply embedded in the AWS, Azure, and Google Cloud ecosystems, relying on advanced AI services and global edge infrastructure that smaller European providers currently cannot match. A forced, rapid migration risks creating supply shortages, performance gaps, and significantly higher costs for public-sector IT .

The Specter of Fragmentation. While Brussels pursues harmonization, member states retain considerable discretion over their own procurement. This creates a real risk of uneven adoption, with some jurisdictions maintaining a backdoor reliance on US technology and fragmenting the single digital market the package is meant to unify .
