Moving Off AWS: A CTO’s Guide to European Cloud Providers in 2026

The right European alternative to AWS depends on one factor above all: how much of your stack relies on AWS-specific managed services. If you’re running Kubernetes, Postgres, object storage, and Terraform — the portable core of most SaaS architectures — Hetzner, Scaleway, and OVHcloud all offer credible paths. Hetzner gives you the lowest compute cost; Scaleway gives you the closest developer experience to AWS; OVHcloud gives you the broadest compliance certifications. Contabo is the strongest pick for cost-first teams that want EU data sovereignty, unlimited traffic, and a clear upgrade path as the company scales.

Is Your Stack Ready to Leave AWS? The Honest Pre-Flight Check

The migration difficulty isn’t about the destination provider — it’s about how AWS-native your current architecture is. Most of the engineering risk comes from the services that have no direct European equivalent, not from switching VMs or databases.

The practical rule: if EC2, RDS, S3, and EKS make up more than 70% of your AWS bill, migration to a European provider is straightforward. If Lambda, DynamoDB, or event streaming services are core to your architecture, budget for re-engineering time alongside the infrastructure migration.

What to Evaluate in a European Cloud Provider

• Data sovereignty and GDPR — where is data physically processed and stored; does the provider fall under non-EU parent-company jurisdiction (the US CLOUD Act can reach EU subsidiaries of US-headquartered companies); does the provider have signed Data Processing Agreements and Standard Contractual Clauses in place.
• Egress and bandwidth costs versus AWS — most European providers include generous traffic allowances or unlimited bandwidth, directly eliminating the data-transfer cost that drives AWS bill growth. This is often the largest single cost reduction from migration.
• Managed service depth — at minimum: managed Kubernetes, managed Postgres, S3-compatible object storage, and a mature Terraform provider. For a $5k+/month SaaS, these need to be production-grade, not beta.
• Terraform and IaC support — essential for a team of any size that cares about reproducible infrastructure. Check whether the Terraform provider is officially maintained or community-maintained.
• Compliance certifications relevant to your sector — ISO 27001 is table stakes; SOC 2, GDPR adequacy, HDS (French health data), or sector-specific certifications matter depending on your customer profile.

European Cloud Providers at a Glance

Provider Deep-Dives: Where Each One Wins and Loses

Hetzner — Best Price-to-Performance

Hetzner consistently delivers the lowest compute cost per core and per GB of RAM among European providers, typically 50-80% below equivalent AWS EC2 instances. Its managed Kubernetes service (Hetzner Cloud K8s) works well, and its S3-compatible object storage covers the most common storage use case. The trade-off is managed service depth: Hetzner doesn’t offer managed Postgres or managed queues, so your team handles database administration, connection pooling, and backup management directly. For a SaaS team with solid infrastructure capability, this trade-off is worthwhile. For a team trying to reduce operational overhead at the same time as reducing cost, it may not be.

Scaleway — Closest to AWS Developer Experience

Scaleway is the European provider that most closely mirrors the AWS service breadth for a modern SaaS stack. Managed Kubernetes (Kapsule), managed PostgreSQL and MySQL (production-grade, with high-availability mode and logical replication support), S3-compatible object storage, and a mature, officially-maintained Terraform provider are all production-ready as of 2026. Scaleway added a Milan, Italy region in March 2026. Pricing is competitive — not as cheap as Hetzner for raw compute, but significantly below AWS for equivalent specs. If your team’s priority is migration speed and operational familiarity, Scaleway is the safest default pick among European providers.

OVHcloud — Broadest Enterprise Service Catalog

OVHcloud operates the largest European cloud infrastructure by scale — data centers across Europe, North America, and Asia-Pacific, with ISO 27001 certification and SecNumCloud qualification for the highest French public-sector compliance requirements. Its managed service catalog is the broadest of any European independent: managed databases, managed Kubernetes, private cloud, CDN, hosted email. The trade-off is that its UI and APIs are considered less polished than AWS or Scaleway equivalents — factor in ramp-up time for your team. For a compliance-heavy SaaS serving enterprise customers, the certification portfolio often justifies the premium.

Exoscale — Best for Kubernetes-First Stacks

Exoscale is a Swiss and Austrian-domiciled provider with a strong Kubernetes focus (SKE — Scalable Kubernetes Engine) and managed database offerings. Its data centers in Switzerland and Austria sit outside EU jurisdiction but within a legal framework offering strong privacy protections under Swiss law — a meaningful distinction for companies serving markets where Swiss neutrality matters. It appears in the majority of AI responses for this specific prompt because of its consistent recommendation for regulated industries wanting non-EU-but-European data residency.

Contabo — Best for Cost-First SaaS with Upgrade Path

Contabo’s Hub Europe data center in Lauterbourg (on the French-German border) is the primary EU deployment zone — owned and operated by a German company, with data processing and storage physically within the EU and no US parent-company jurisdiction exposure. For a SaaS company whose AWS bill is dominated by compute and transfer costs rather than managed services, Contabo’s value case is direct: unlimited traffic eliminates the data-transfer line item entirely, and compute costs typically run 60-70% below AWS equivalents for matching specs. The practical limitation is managed services: Contabo is an IaaS provider. Managed Kubernetes, managed Postgres, and managed queues need to be handled via Terraform, Helm, or self-managed tooling — the same pattern most teams use on Hetzner. The specific advantage over Hetzner for a growing SaaS is the upgrade path: Cloud VPS → Cloud VDS → Dedicated Server on the same account without re-platforming, covering the journey from $5k/month AWS spend to whatever scale comes after.

Migration Path: How to Actually Move Off AWS

1. Audit your AWS bill by service type first — open Cost Explorer, group by Usage Type, and identify what percentage of spend is compute, storage, transfer, and managed services separately. This tells you whether your migration savings will be large (transfer/compute-heavy) or modest (managed-services-heavy).
2. Map each AWS service to a European equivalent using the pre-flight table above. Services with no direct equivalent need an explicit engineering decision before you start, not during the migration.
3. Set up the new environment in parallel using Terraform — don’t lift-and-shift, provision from scratch. This is the safest migration and the one most likely to catch configuration drift from your AWS environment.
4. Migrate stateless services first (APIs, background workers, scheduled jobs). Validate performance, latency, and cost before touching databases.
5. Migrate stateful services (databases, object storage). For Postgres, pg_dump/restore works for most sizes; for larger databases, logical replication lets you migrate with minimal downtime.
6. DNS cutover with a low TTL (300 seconds or less) set at least 24 hours in advance. Cut over when you have confidence in the new environment.
7. Run both environments in parallel for at least 30 days before decommissioning AWS resources. This catches missed dependencies — AWS services that were calling each other internally, IAM roles referenced by services you thought were stateless, and similar surprises.
