EU Sovereign Cloud vs. Hyperscalers: Why Compliance Matters for Public Data

Understanding EU Data Sovereignty Requirements

EU data sovereignty requirements stem from multiple legislative drivers:

1. GDPR and Cross-Border Data Transfers

Under GDPR, transferring personal data outside the EU requires specific safeguards. The EU-US Data Privacy Framework provides one pathway, but some organizations prefer to keep EU data within EU borders entirely.

2. National Cloud Certifications

Several EU member states have established national cloud security certifications:

• SecNumCloud (France): ANSSI certification requiring data residency in France
• C5 (Germany): BSI criteria for cloud services used by German public sector
• EUCS/EUCC: European-wide certification scheme for cloud services

3. NIS2 Supply Chain Requirements

NIS2 requires essential entities to assess and manage ICT supply chain risks, including evaluating vendor security practices and data handling.

Hyperscalers: The Global Option

Major cloud providers (AWS, Azure, Google Cloud) offer significant advantages:

Advantages

• Scale and maturity: Global infrastructure with proven reliability
• Feature breadth: Comprehensive service offerings
• Cost efficiency: Economies of scale
• Innovation pace: Rapid deployment of new features

Compliance Considerations

• Data centers in multiple regions (including EU)
• EU-specific compliance offerings (e.g., AWS EU regions)
• C5 and SecNumCloud certifications for specific services
• Potential concerns: CLOUD Act, foreign government access

EU Sovereign Cloud: The Regional Option

EU-based cloud providers offer alternative advantages:

Advantages

• Data residency guarantee: All data remains in EU
• Simplified compliance: Direct alignment with national certifications
• Transparent supply chain: Clearer visibility into infrastructure
• Local support: EU-based support teams

Considerations

• Smaller scale and geographic coverage
• Potentially higher costs
• Feature gaps compared to hyperscalers
• Fewer integration options

Making the Right Choice for Your Organization

When evaluating cloud options for public sector workloads, consider:

1. Data Classification

Not all data requires the same protection level. Classify your workloads:

• Highly sensitive: National security, healthcare records → Consider sovereign cloud
• Standard government data:
• Public information: Minimal sovereignty requirements

2. Compliance Requirements

Your specific regulatory environment matters:

• French government agencies → SecNumCloud likely required
• German public sector → C5 compliance
• EU-wide operations → EUCC certification

3. Supply Chain Risk

Consider the vendor's overall security posture:

• What certifications do they hold?
• How transparent is their supply chain?
• What happens if they experience a breach?

A Hybrid Approach

Many organizations are adopting hybrid strategies:

• Highly sensitive workloads: EU sovereign cloud with national certification
• Standard workloads: EU region of major hyperscalers
• Development/test: Cost-effective options as appropriate
