European Alternatives to AWS, Azure and GCP — 2026 Comparison
A comprehensive comparison of European cloud providers versus American hyperscalers. IaaS, object storage, managed databases, CDN: which sovereign cloud should your Belgian SME choose in 2026?
European Cloud Has Matured
Five years ago, choosing a European cloud provider meant accepting meaningful trade-offs on features, reliability, or geographic coverage. In 2026, that is no longer the case. The European sovereign cloud ecosystem has transformed profoundly: providers have invested heavily in their infrastructure, expanded their managed services catalogues, and obtained the regulatory certifications required by the most demanding sectors.
For a Belgian SME, the choice of a cloud provider is now a fully strategic decision — not merely technical, but legal, financial, and ethical. This comparison gives you the information you need to decide with confidence.
Why Leave AWS, Azure, or GCP?
Before comparing alternatives, let us be clear about the objective reasons for seeking one.
The US CLOUD Act grants American authorities the right to access data held by US-incorporated companies, regardless of where the servers are physically located. Your data on AWS Frankfurt remains legally accessible to US federal agencies.
Instability of the EU-US transfer framework: the Data Privacy Framework adopted in 2023 is being challenged before the Court of Justice of the EU. A "Schrems III" ruling could invalidate this mechanism again, leaving companies that rely on it in a position of non-compliance overnight.
The real cost of hyperscalers: egress fees, opaque pricing on managed services, and proliferating product tiers create unpredictable bills. Organisations migrating to European providers regularly report savings of 30 to 60% on infrastructure costs.
Strategic dependency: concentrating critical services with a single provider subject to a foreign jurisdiction creates a structural vulnerability that boards and CIOs still underestimate too often.

By Use Case: Which Provider to Choose?
IaaS and compute
Recommendation: Hetzner for the best price-performance ratio, OVHcloud for advanced certification requirements, Scaleway for modern cloud-native architectures.
Object storage (S3 replacement)
Recommendation: OVHcloud Object Storage or Scaleway Object Storage for full S3 compatibility with an API identical to AWS S3. Hetzner Object Storage for budget-conscious projects.
Managed databases
Recommendation: Scaleway Managed Databases (PostgreSQL, MySQL, Redis) or UpCloud Managed Databases for teams wishing to delegate management. OVHcloud also offers Managed Databases within its Public Cloud range.
European CDN
European cloud providers offer basic CDN capabilities, but for a performant CDN, consider complementing with Bunny.net (Slovenian company, global presence, highly competitive pricing) or Fastly (European presence, usage-based pricing).
Collaborative suite
Clear recommendation: Infomaniak for a complete, turnkey suite. For self-hosting: Nextcloud + OnlyOffice on Hetzner.
Migration Considerations
Evaluate before you migrate
Do not migrate blindly. Before selecting a provider, conduct a proof of concept:
- Deploy a staging environment on the target provider
- Test network performance from your Belgian offices (latency, throughput)
- Validate the compatibility of your tools with the proposed managed services
- Obtain precise quotes based on your actual consumption
Key technical considerations
S3 compatibility: all providers listed above offer S3-compatible object storage. Your applications using the AWS S3 SDK will work with a simple endpoint change.
Kubernetes: OVHcloud, Hetzner, Scaleway, and UpCloud offer CNCF-conformant Managed Kubernetes. Your Helm charts and CI/CD pipelines will be largely reusable.
Terraform: official or community Terraform providers exist for OVHcloud, Hetzner (very mature), Scaleway, and Infomaniak. Your infrastructure-as-code is transferable.
Network: evaluate latencies from your offices. For a Belgian SME, OVHcloud datacenters in Roubaix, Hetzner in Falkenstein, or Scaleway in Paris offer excellent latencies.
Recommended migration strategy
- Audit the existing setup: inventory all your AWS/Azure/GCP services and their interdependencies
- Isolate workloads: identify applications that can migrate independently
- Prioritise: start with stateless workloads (websites, stateless APIs)
- Migrate in waves: migrate in batches, maintaining temporary coexistence
- Validate: test in production with real traffic before decommissioning the old environment
The Verdict for Belgian SMEs in 2026
There is no universal provider. Here are our recommendations by profile:
Technical SME with a DevOps team: Hetzner as primary infrastructure, complemented by Scaleway for advanced managed services.
SME seeking a turnkey solution: Infomaniak for the collaborative suite and OVHcloud for infrastructure.
Regulated sector (healthcare, finance, public sector): OVHcloud with HDS/SecNumCloud certification.
Budget-conscious startup: Hetzner, full stop. The price-performance ratio is unbeatable in Europe.
Enterprise seeking maximum performance: UpCloud for I/O-intensive workloads, Scaleway for GPU/AI projects.
What is certain: in 2026, remaining exclusively on AWS, Azure, or GCP as a European SME is increasingly difficult to justify — technically, financially, and above all, legally.
