Data sovereignty has moved from a compliance checkbox to a boardroom priority. Between GDPR enforcement actions, the invalidation of Privacy Shield, and the US CLOUD Act's reach into American-owned hyperscalers, European businesses face real legal exposure if their data sits on infrastructure they don't fully control.
EU sovereign cloud doesn't mean slower or more expensive by default anymore. Here's how the main players stack up.
1. OVHcloud
France-based OVHcloud is Europe's largest cloud provider by infrastructure footprint, with datacenters across France, Germany, Poland, and beyond. It operates entirely under French and EU jurisdiction.
Pros
- Fully EU-owned and operated — no US parent company exposure
- Competitive pricing, especially for bare metal and VPS
- Wide range of services: compute, object storage, managed Kubernetes, AI/ML tools
- Strong GDPR compliance posture; certifications include ISO 27001, HDS (French health data)
- Public Sector Cloud (SecNumCloud qualification in progress)
Cons
- Developer experience and documentation lag behind AWS/GCP
- Managed services ecosystem is thinner — less plug-and-play than hyperscalers
- Support quality can be inconsistent on lower-tier plans
- UI/UX of the control panel is dated
Best for
Cost-sensitive SMEs, startups wanting EU residency without hyperscaler bills, and companies with straightforward compute/storage needs.
| Attribute | Rating |
|---|---|
| EU Data Residency | Yes (guaranteed) |
| Pricing | ★★★★★ (most competitive) |
| Managed Services | ★★★☆☆ |
| Compliance Certs | ISO 27001, HDS, SOC 2 |
| Support | ★★★☆☆ |
2. Hetzner Cloud
Hetzner is a German provider known for punching well above its weight on price-to-performance. Its cloud offering runs out of Nuremberg, Falkenstein, Helsinki, and Ashburn (US — avoid for EU-only workloads).
Pros
- Exceptional value — often 3–5× cheaper than AWS for equivalent compute
- German-owned and operated, EU-based datacenters available
- Clean, simple API and Terraform provider
- Reliable uptime track record
- Good managed Kubernetes (Hetzner Cloud Kubernetes)
Cons
- Limited service portfolio — no managed databases, AI, or advanced networking out of the box
- Not suitable for highly regulated industries (no ISO 27001 for cloud at the time of writing)
- Smaller geographic footprint
- No SLA-backed enterprise support tier
Best for
Dev/staging environments, bootstrapped startups, developer tools, and any workload where price is the primary constraint and you're comfortable managing your own stack.
| Attribute | Rating |
|---|---|
| EU Data Residency | Yes (if EU DCs selected) |
| Pricing | ★★★★★ (best in class) |
| Managed Services | ★★☆☆☆ |
| Compliance Certs | Limited |
| Support | ★★☆☆☆ |
3. Scaleway
Scaleway is the cloud arm of Iliad Group (France). It has been positioning itself as the "developer-friendly EU cloud" with a modern UX and a growing set of managed services including serverless functions, managed databases, and GPU instances for AI workloads.
Pros
- French-owned, EU datacenters (Paris, Amsterdam)
- Modern developer experience — clean console, good API docs
- Growing AI/ML offering including H100 GPU instances
- Managed Postgres, Redis, and Kafka
- Serverless and edge functions
Cons
- Still maturing — some services go in and out of beta
- Smaller global footprint than OVHcloud
- Can't yet match hyperscalers on breadth of enterprise services
- Less established enterprise track record
Best for
AI/ML startups wanting EU data residency, developer teams that prioritise UX, companies building modern cloud-native apps who want to avoid AWS without sacrificing DX.
| Attribute | Rating |
|---|---|
| EU Data Residency | Yes (FR/NL) |
| Pricing | ★★★★☆ |
| Managed Services | ★★★★☆ |
| Compliance Certs | ISO 27001, HDS |

4. Deutsche Telekom Open Telekom Cloud
The Open Telekom Cloud (OTC) is T-Systems' (Deutsche Telekom subsidiary) public cloud offering, built on OpenStack and hosted exclusively in German Telekom datacenters in Germany.
Pros
- Fully German infrastructure with Telekom-grade SLAs
- Strong compliance posture: ISO 27001, ISO 27017, ISO 27018, C5 (BSI)
- Backed by one of Europe's largest telcos — enterprise-grade reliability
- GDPR-compliant by design with data processing agreements
- Public sector and healthcare ready
Cons
- More expensive than OVHcloud or Hetzner
- OpenStack-based UI is less intuitive than modern clouds
- Innovation pace is slower than hyperscalers

Best for
German enterprises, public sector organisations, healthcare companies, and any business where BSI C5 or stringent German compliance is a hard requirement.
| Attribute | Rating |
|---|---|
| EU Data Residency | Yes (Germany only) |
| Pricing | ★★★☆☆ |
| Managed Services | ★★★☆☆ |
| Compliance Certs | ISO 27001, C5 (BSI), SOC 2 |

5. IONOS Cloud
IONOS (United Internet AG, Germany) has been quietly building a serious cloud offering with datacenters across Germany, the UK, Spain, and the US. Rebranded from 1&1 Cloud, it's more enterprise-ready than its hosting-company origins suggest.
Pros
- German-owned, EU datacenters
- Competitive pricing with transparent costs
- Good managed Kubernetes and S3-compatible object storage
- ISO 27001 certified
- Solid virtual networking and firewall tooling
Cons
- Less brand recognition than OVHcloud or Hetzner

- Documentation quality is uneven
Best for
Mid-market European businesses looking for a reliable German-owned alternative to hyperscalers, particularly if they already use IONOS for hosting.
| Attribute | Rating |
|---|---|
| EU Data Residency | Yes (DE/ES/UK) |
| Pricing | ★★★★☆ |
| Managed Services | ★★★☆☆ |
| Compliance Certs | ISO 27001 |
| Support | ★★★☆☆ |

How to Choose
There's no single best EU sovereign cloud — it depends on your constraints:
- Regulated industry (health, finance, public sector): OTC or OVHcloud with relevant certifications
- Tight budget, simple infrastructure: Hetzner for dev, OVHcloud for prod
- AI/ML workloads: Scaleway's GPU instances or OVHcloud's AI tools
- German compliance (BSI C5): OTC is the clearest path
- Developer experience matters: Scaleway leads on UX
The good news: switching costs between these providers are lower than migrating away from AWS or Azure, especially if you're using containers and infrastructure-as-code from day one.
