What Is Digital Sovereignty and Why Does It Matter for Europe?
The vast majority of cloud infrastructure today is controlled by U.S.-based hyperscalers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.
These companies operate under U.S. law — most notably the CLOUD Act, which gives U.S. authorities the right to access data, even if it’s stored in European data centers.
This legal loophole creates an enormous risk. European governments, hospitals, banks, and startups often host sensitive workloads on foreign infrastructure without realizing they’re potentially exposing themselves to surveillance, data requests, and jurisdictional conflicts. Digital sovereignty is about correcting that imbalance — ensuring that European data stays in Europe, governed by European laws.
But it’s more than just regulation. Digital sovereignty also touches on values — privacy, transparency, innovation, and economic sustainability. It’s a vision of a Europe that’s not just connected, but digitally independent.
The Legal and Ethical Imperatives Behind Sovereign Cloud Choices
When a European organization uses a U.S.-based cloud provider, it may be fully GDPR-compliant on paper, but in reality, there’s a major legal contradiction. That’s because foreign laws can override EU protections through extraterritorial reach. The U.S. CLOUD Act is a prime example. It allows American law enforcement to demand access to data, no matter where it’s stored, as long as it’s held by a U.S.-controlled entity.
This creates a fundamental conflict with the General Data Protection Regulation (GDPR) — which mandates strict data processing, protection, and transparency rules for all EU citizens. If a cloud provider is subject to both laws, whose orders do they follow?
This ethical and legal tension has spurred the development of sovereign cloud solutions. EU-based cloud providers offer an escape from this conundrum. They’re headquartered and operated under European jurisdiction, meaning they can comply fully with EU data protection laws without foreign interference.
Why Europe Needs Its Own Cloud Ecosystem
Dependency on Foreign Hyperscalers
As of 2025, American tech giants control more than 70% of Europe’s cloud infrastructure. That’s a staggering figure — and one that leaves little room for self-determination.
Let’s take, for example, Belgium – Microsoft (with US stored data) has 70% of the market for cloud infrastructure. In Sweden, over 57% of public digital infrastructure — including cities and government services — runs on Microsoft mail servers. In Finland — 77%, Belgium — 72%, Netherlands — 60%, Norway — 64%.

Whether it’s a local municipality storing its citizens’ health records or a fintech startup handling millions of transactions, chances are, their data sits on servers operated by foreign entities.
Worse still, this monopoly can lead to vendor lock-in. Companies get tied into proprietary ecosystems that make switching costly and complicated. In contrast, European providers often focus on open-source compatibility and multi-cloud strategies, giving users more freedom and flexibility.
Europe needs its own cloud, not to build walls but to ensure it can compete fairly, uphold its laws, and foster a vibrant digital economy rooted in democratic principles.
Key Features to Look for in a European Cloud Provider
Data Residency Within EU Borders
One of the most essential features to demand from any cloud provider in Europe is guaranteed data residency within the EU. Why? Because where data lives determines which laws apply to it. If your business stores sensitive customer information — emails, financial records, medical data — on a cloud hosted in the EU, it’s protected by the General Data Protection Regulation (GDPR) and other local laws.
Storing data in the EU ensures:
- It cannot be accessed by non-EU jurisdictions without violating EU law.
- It remains subject to EU-based audit, regulation, and enforcement.
- It aligns with emerging policies like the EU Data Governance Act and Digital Services Act.
EU-based cloud providers like OVHcloud, Scaleway, Hetzner, and Aruba Cloud maintain fully European data center infrastructure, with no dependency on U.S. control. This is particularly important for regulated industries like healthcare, banking, legal, and public services, where compliance breaches can lead to devastating penalties and reputational damage.
Data sovereignty starts with location — but it ends with legal control. Choosing a provider that guarantees both gives you peace of mind and legal clarity.
Full Compliance with EU Data Laws
True digital sovereignty goes beyond location — it demands full legal compliance. A trustworthy EU cloud provider should not only operate under GDPR, but also comply with:
- NIS2 Directive for critical infrastructure security
- ISO/IEC 27001 for information security management
- EU Cybersecurity Act standards
- HDS (Health Data Hosting) if you’re in healthcare
The best providers will also publish compliance documentation, undergo regular third-party audits, and offer Data Processing Agreements (DPAs) aligned with EU standards.
Don’t forget that compliance also includes how a provider handles cross-border data flows, encryption, access controls, and breach notifications. EU-based providers are more likely to have baked-in privacy policies that require less negotiation or oversight on your part.
Transparent Pricing and Vendor Lock-In Avoidance
One common complaint with U.S. hyperscalers is the complexity and unpredictability of pricing. Want to know how much it costs to move 10TB of data out of AWS? You might need a PhD in fine print. By contrast, many European cloud providers prioritize pricing transparency.
Providers like Hetzner and Scaleway offer flat-rate pricing, pay-as-you-go models, and clear invoicing structures. This allows businesses to forecast cloud costs more accurately, especially important for SMEs and startups.
Another key differentiator is freedom from vendor lock-in. Many European providers focus on open-source compatibility and open APIs, which makes it easier to move workloads between cloud platforms or even back on-premises. That’s crucial for long-term agility and cost control.
If you’re planning a cloud strategy for the next 5–10 years, flexibility should be as important as functionality.

Challenges in Adopting EU Cloud Providers
Lack of Feature Parity with Global Giants
Despite their growth, many EU cloud providers still lack the breadth of services offered by hyperscalers. If your organization relies on cutting-edge AI/ML pipelines, advanced serverless infrastructure, or global CDN optimization, you may find some gaps.
For example:
- OVHcloud may not match AWS in managed AI services.
- Scaleway doesn’t yet offer the global distribution options of Google Cloud.
- Hetzner, while powerful, lacks native integrations for enterprise software stacks like Salesforce or Microsoft 365.
How to Choose the Right EU Cloud Provider
Assessing Security, Scalability, and Support
Choosing the right European cloud provider means balancing technical capabilities with regulatory requirements and business goals. Here’s a quick checklist to guide your decision:
- Security: Does the provider offer end-to-end encryption, ISO 27001 certification, DDoS protection, and GDPR-compliant data handling?
- Scalability: Can the infrastructure scale horizontally and vertically? Are there options for load balancing, container orchestration, or serverless deployment?
- Support: Is there 24/7 customer support in your local language? Do they offer clear Service Level Agreements (SLAs) and migration support?
- Ecosystem Fit: Does the provider support open APIs, DevOps tooling, and integration with your software stack?
- Data Jurisdiction: Are your workloads 100% located in EU jurisdictions, and not subject to non-EU laws like the CLOUD Act?
Providers like Scaleway are ideal for developers and agile startups, while T-Systems suits highly regulated enterprises. Hetzner is unbeatable for performance-per-euro, and OVHcloud delivers full-stack capabilities at scale.
Hybrid and Multi-Cloud Sovereignty Strategies
Not every workload needs to be moved off AWS or Azure today. A practical approach for many businesses is to adopt a hybrid or multi-cloud model:
- Use hyperscalers for global edge services or non-sensitive content delivery.
- Deploy critical workloads — like customer databases, compliance logs, or analytics pipelines — on sovereign EU clouds.
- Leverage Kubernetes, Terraform, and Ansible to orchestrate resources across environments with minimal lock-in.
This strategy offers the best of both worlds: access to global performance when needed, and sovereignty where it matters. Just make sure your orchestration tools support cloud-agnostic deployments.
Conclusion
Europe stands at a crossroads. It can continue to rely on foreign digital giants— or it can take control of its digital destiny. Choosing a European cloud provider is about much more than IT infrastructure.
It’s about:
- Preserving privacy
- Empowering local innovation
