Hosting a Web App on EU Sovereign Cloud vs AWS: Cost in Berlin

The verdict in three sentences

For a 2,000-user business application, a German provider such as Hetzner or IONOS costs half as much as AWS or less for the same scope, with ample performance. AWS Frankfurt makes sense if you rely on its advanced managed services or serve global markets, but egress traffic inflates the bill quickly. If public sector or healthcare clients require BSI C5 attestation or strict EU sovereignty, decide before go-live, because a migration costs 5,000 to 12,000 EUR.

Monthly cost for the same scope in 2026

Comparison for a typical app: 2 application servers, a managed PostgreSQL database with replica, 500 GB of object storage, daily backups and about 1 TB of monthly egress. 2026 orders of magnitude, before commitment discounts. (In France, the equivalent ranges are 150 to 300 EUR at OVHcloud and 180 to 350 EUR at Scaleway.)

*Hetzner has no fully managed PostgreSQL in its core cloud: budget either a self-managed setup with replication or a third-party managed service, plus a few hours of ops a month.

Egress is the line that surprises most AWS customers: about 0.09 USD per GB beyond the free allowance. Hetzner includes 20 TB of traffic per instance in the EU.

Sovereignty, compliance and client requirements

Price is only one criterion. Public, healthcare or critical infrastructure clients set requirements that rule out some offers.

If a federal agency, a Land authority or a KRITIS operator is among your clients, ask during scoping whether C5 or a specific sovereignty level is mandatory.

FAQ

How much does hosting a 2,000-user business app cost?

Budget 100 to 220 EUR a month at Hetzner, 150 to 320 EUR at IONOS and 300 to 700 EUR at AWS. 1 to 3-year commitments cut AWS by 30 to 40%.

What is BSI C5 and do we need it?

It is the German Federal Office for Information Security cloud attestation. Public sector and healthcare buyers increasingly require it; many SMEs serving private clients do not need it.

How much does migrating from AWS to an EU provider cost?

5,000 to 12,000 EUR for a mid-size containerised app, over 2 to 4 weeks. Heavy use of proprietary AWS services can raise that figure.

Is AWS still relevant for a German SME?

Yes, if you use advanced services (queues, managed AI, multi-region) or most of your clients are outside Europe.

Does GDPR forbid AWS?

No. The Frankfurt region and the EU-US Data Privacy Framework allow compliant use, but the CLOUD Act remains a point of attention for sensitive data.
