The verdict in three sentences
Sovereign EU application hosting budgets at 220 to 640 EUR/month for an SME, depending on power and high availability. OVH and Scaleway cover GDPR with no transfer outside the EU, whereas a US cloud demands extra contractual safeguards and legal risk. Compliance (register, DPA, encryption, retention) is a manageable one-off cost against data-protection fines.
2026 hosting comparison: OVH, Scaleway, US cloud
The choice hinges on sovereignty, latency and TCO. Here are the key line items for an SME business app in 2026.
| Line item | OVH (EU) | Scaleway (EU) | US cloud |
|---|---|---|---|
| Application VM | 90-220 EUR/mo | 100-250 EUR/mo | 110-280 EUR/mo |
| Managed database | 60-160 EUR/mo | 70-180 EUR/mo | 80-200 EUR/mo |
| Backups + monitoring | 40-100 EUR/mo | 45-120 EUR/mo | 50-130 EUR/mo |
| WAF / CDN | 30-80 EUR/mo | 35-90 EUR/mo | 40-100 EUR/mo |
| Data location | EU | EU | Outside EU (clauses) |
| Native GDPR compliance | Yes | Yes | Conditional |
Typical SME infra budget: 220 to 640 EUR/month by redundancy. The price gap with US cloud is small, but decisive on sovereignty and on the compliance workload.
The cost of GDPR compliance
Compliance is not just a document: it is a technical and organisational chain. Here are the 2026 line items and their orders of magnitude.
| GDPR workstream | Content | 2026 cost (order of magnitude) |
|---|---|---|
| Processing register | Personal-data mapping | 1,500-3,500 EUR |
| Sub-processor DPAs | Host/vendor contracts | 800-2,000 EUR |
| Encryption at rest + transit | TLS, DB encryption, secrets | Infra + 1-3 days |
| Retention policy | Auto purge, anonymisation | 1,000-2,500 EUR |
| Light audit / pentest | Intrusion test, fixes | 3,500-8,000 EUR |
| DPA support | Audit prep, external DPO | 2,000-6,000 EUR/yr |
A regulator audit can lead to sanctions; conversely, a clean baseline costs a few thousand euros one-off and is maintained cheaply within the run.

Mini case study
Karim, IT director at a 60-staff healthcare SME, hosts an app processing patient data. He picks Scaleway (EU): VM 180 + DB 140 + backups/monitoring 90 + WAF/CDN 70 = 480 EUR/month, i.e. 5,760 EUR/year. He adds initial compliance (register 2,500 + DPA 1,200 + retention 1,800 + pentest 5,000) = 10,500 EUR one-off. Against fine risk and lost patient trust, this sovereign baseline is health insurance for the IT estate: under 0.9% of his annual IT budget for run compliance.
FAQ
What monthly budget to host an app in the EU? Between 220 and 640 EUR/month for an SME depending on high availability, backups and WAF included.
OVH or Scaleway for GDPR? Both host in the EU with no transfer outside and are GDPR-compliant; the choice is about managed services and support, not sovereignty.
Is US cloud banned? No, but it requires standard contractual clauses and a risk assessment; for sensitive data (health, HR), sovereign hosting stays safest.
How much for an audit / pentest? A light pentest with fixes runs 3,500 to 8,000 EUR, external DPO support 2,000 to 6,000 EUR/year.
Is encryption an extra cost? TLS and encryption at rest are near-included in managed infra; budget 1 to 3 days for secrets management and key policy.
