The verdict in three sentences
EU sovereign hosting sits between 200 and 1 000 EUR/month in 2026 depending on load, with OVHcloud, Scaleway or Outscale. The premium over US hyperscalers is moderate, but it buys EU data residency, immunity from the CLOUD Act and often a SecNumCloud qualification. For a public-sector or regulated CIO, the real question is no longer price but reversibility and compliance.
Sovereign vs US cloud: the real comparison
The choice is not about an instance's hourly rate. It engages the jurisdiction applicable to your data, your ability to exit the provider, and your future compliance. Here are the 2026 gaps on the criteria that matter.
| Criterion | US cloud (hyperscaler) | EU sovereign cloud |
|---|---|---|
| Monthly cost, average app | 150 - 750 EUR | 200 - 1 000 EUR |
| Data residency | variable / multi-region | guaranteed EU |
| CLOUD Act exposure | yes | no |
| SecNumCloud qualification | no | available |
| Contractual reversibility | limited | enforceable |
| Native-language support | partial | native |
| Public-tender eligibility | often excluded | compliant |
Sizing and budgeting
Real cost depends on load, storage and service level. A well-sized project avoids both under-provisioning (outages) and waste. 2026 orders of magnitude for a line-of-business app hosted sovereignly.
| App profile | Resources | Monthly cost 2026 (EUR) |
|---|---|---|
| Showcase app + light API | 2 vCPU / 4 GB / 40 GB | 200 - 320 |
| SME line-of-business app | 4 vCPU / 16 GB / 200 GB | 400 - 650 |
| Loaded multi-tenant app | 8 vCPU / 32 GB / 500 GB + managed DB | 650 - 1 000 |
| Add DR / backups | replication + backups | +100 - 250 |
| SecNumCloud support | audit + dossier | 6 000 - 15 000 (one-off) |
Mini case study
Marc, CIO of a public body in Bordeaux, must migrate a citizen-management app hosted in the US. The brief mandates data residency in the EU and reversibility. He selects a sovereign offer at 550 EUR/month (vs 450 EUR at the hyperscaler), i.e. 1 200 EUR/year premium. In return, the body regains public-tender eligibility and removes its CLOUD Act exposure: a 1 200 EUR premium that unlocks six-figure tenders.

Is SecNumCloud mandatory?
Not for every app, but it is required for sensitive state data and strongly recommended for the public sector. A host's qualification is issued by the national security agency; project support costs 6 000 to 15 000 EUR.
Is sovereign much more expensive than US?
No, the 2026 gap is around 10 to 30% on a standard app. The difference narrows as EU providers move up-market on managed services.
What does reversibility mean concretely?
Your ability to retrieve data and configurations to switch provider without lock-in. A documented exit plan (open formats, DB export, IaC) must be in the contract.
Can we stay GDPR-compliant on a US cloud?
Possible but complex: standard contractual clauses, supplementary measures and transfer analysis. Sovereign radically simplifies the compliance demonstration.
How long to migrate to a sovereign cloud?
From 2 to 8 weeks depending on complexity. A containerised app with IaC migrates in 2-3 weeks; an architecture coupled to proprietary services needs partial rework.
