The verdict in three sentences
For a B2B site serving the EU, sovereign providers like OVH and Scaleway offer data residency, native GDPR compliance and Cloud Act protection at a monthly cost often below the US cloud. AWS and GCP remain unbeatable on ecosystem and scaling, but demand vigilance on cross-border data transfers and a solid DPA. For most SMEs, sovereign hosting is the default; the US cloud is justified for specific technical needs.
Cost, compliance and performance compared
Here are the 2026 ballpark figures for a mid-traffic B2B site (corporate brochure + blog + forms).
| Criterion | OVH / Scaleway | AWS / GCP |
|---|---|---|
| Monthly cost | 25 - 120 EUR | 40 - 200 EUR |
| Data location | France / EU | Configurable, often US default |
| Cloud Act | Not applicable | Applicable |
| GDPR DPA | Native | To configure |
| Uptime SLA | 99.9% | 99.95 - 99.99% |
| Service ecosystem | Limited | Very rich |
| Support | Local | English (premium paid) |
At equal price, sovereign hosting simplifies compliance: no standard contractual clauses to negotiate, no cross-border transfer analysis, a DPA enforceable before the regulator.
Real compliance cost
The headline server price hides an often-ignored line: compliance. Here is the 2026 annual estimate for an SME.
| Compliance line (year) | Sovereign hosting | US cloud |
|---|---|---|
| Cross-border transfer analysis | 0 EUR | 1,500 - 4,000 EUR |
| DPA drafting/review | 0 - 500 EUR | 1,000 - 2,500 EUR |
| Regulator documentation | 300 - 800 EUR | 800 - 2,000 EUR |
| Annual security audit | 1,000 - 3,000 EUR | 1,500 - 4,000 EUR |
| Total compliance/year | 1,300 - 4,300 EUR | 4,800 - 12,500 EUR |
The compliance gap far exceeds the server price difference: for an SME, sovereign hosting saves 3,000 to 8,000 EUR/year in regulatory overhead.
Mini case study
Nadia, DPO of an industrial SME in Dublin (80 staff), hosts a site and a contact form collecting customer data. On AWS she paid 110 EUR/month for the server but 6,500 EUR/year in compliance (transfer analysis, DPA, audit). She switches to a sovereign provider at 70 EUR/month with 2,800 EUR/year in compliance. Annual saving: (110-70) x 12 + (6,500-2,800) = 480 + 3,700 = 4,180 EUR/year, not counting reduced regulatory fine risk (up to 4% of turnover). The hosting migration, billed at 3,500 EUR, pays back in under 11 months.

FAQ
Is the US cloud illegal in the EU?
No, but it requires guarantees: standard contractual clauses, transfer impact analysis, and often reinforced encryption. The Cloud Act remains a real legal risk to document.
Can sovereign providers handle the load?
Yes for the vast majority of B2B sites. They offer 99.9% SLA and capable CDNs. The US cloud keeps the edge on massively distributed architectures.
How much does compliance really cost?
Between 1,300 and 4,300 EUR/year on sovereign hosting, 4,800 to 12,500 EUR/year on US cloud for an SME. The gap comes mainly from cross-border transfer analysis.
Can I migrate without downtime?
Yes, a well-planned hosting migration (progressive DNS switch, overlap period) happens with no perceptible downtime. Budget 2,500 to 5,000 EUR depending on complexity.
Is server price the only criterion?
No, and that is the classic mistake. Total cost includes compliance, support and regulatory risk. A server 30 EUR cheaper can cost 4,000 EUR more in compliance.
