Vendor Sovereignty Assessment Framework

You're evaluating cloud vendors for sensitive workloads. The question is no longer "Is this cloud sovereign?" but "What level of sovereignty do we actually need, and what's it going to cost?"

This assessment framework walks you through a 6-category evaluation (data residency, CLOUD Act exposure, encryption control, feature completeness, cost, vendor lock-in) and produces a decision matrix comparing Microsoft Sovereign Cloud, AWS European Cloud, independent EU vendors, and on-premises alternatives.

What's in the Framework

6-Category Assessment Rubric

  • Data Residency: Where does your data physically sit? Who controls access?
  • CLOUD Act Exposure: Is your vendor subject to US legal demands? What's your mitigation?
  • Encryption Control: Who holds the encryption keys? (You, vendor, shared)
  • Feature Completeness: Does the platform support your required workloads?
  • Cost & Timeline: What's the 3-year TCO? How long until it breaks even?
  • Vendor Lock-in: If you need to exit, what's the effort and cost?

Platform Comparison Matrix

  • Microsoft Sovereign Cloud (Europe)
  • AWS European Sovereign Cloud
  • Independent EU vendors (OVHcloud, Deutsche Telekom)
  • On-premises with managed operations

Decision Criteria & Trade-offs

  • Sovereignty levels (1-4 framework from low to maximum control)
  • Cost-benefit analysis across 3, 5, and 10-year horizons
  • Regulatory alignment (GDPR, Schrems II, sector-specific mandates)
  • Operational maturity requirements for each option
  • Risk assessment and mitigation strategies

How It Works

The framework is structured around your data classification and risk tolerance. You answer 4-5 questions about your environment (data sensitivity, budget, regulatory requirements, operational maturity), and the tool produces:

1. Your Sovereignty Level

Based on your answers, the framework recommends which level (1-4) is appropriate and cost-effective.

2. Platform Comparison

Scored across the 6 categories. Shows which platforms win on sovereignty, cost, features, and operational burden.

3. Implementation Roadmap

If you choose Level 2 or 3, here's the 6-18 month project roadmap: staffing, infrastructure, vendor negotiation, data migration.

4. Risk Assessment

For each platform: regulatory compliance gaps, CLOUD Act exposure quantified, encryption strategy, incident response plan.

The Honest Take

This framework doesn't sell you on any particular vendor. It shows you the trade-offs:

The right choice depends on your data sensitivity, budget, and acceptable operational overhead. This framework helps you make that decision.
