GDPR and Cloud in 2026: Is EU Data Residency Enough?

Direct answer: yes, public cloud (both AWS and Azure) can be fully GDPR-compliant — both providers offer EU regions, data processing agreements and the necessary certifications. But beware of a common misconception: “data stored in the EU” is not the same as “data beyond the reach of foreign jurisdictions”. Data residency is a technical property; legal sovereignty is a contractual and corporate structure. In 2026 both major platforms address this — Microsoft via the EU Data Boundary and AWS via the new European Sovereign Cloud.

What GDPR actually requires for cloud

A data processing agreement (DPA) under Article 28 — a standard part of both AWS and Microsoft contracts.
A legal transfer mechanism for data leaving the EU — standard contractual clauses (SCCs) or an adequacy decision (EU-US Data Privacy Framework).
Appropriate technical measures — encryption in transit and at rest, access control, logging.
Records of processing activities — knowing where which personal data flows (including support and telemetry).

For a typical company these four points are easier to meet in the cloud than on a server in the basement — the provider supplies certifications, encryption and physical security you would otherwise pay for yourself.

Microsoft EU Data Boundary

The EU Data Boundary covers Microsoft 365, Dynamics 365, Power Platform and most Azure services: customer data and pseudonymised personal data are stored and processed within the EU/EFTA. For most companies this sufficiently answers the “where is our data” question.

The limit: it is a residency commitment, not a jurisdictional one. As a US company, Microsoft remains subject to US law (the CLOUD Act) — in theory even for data stored in the EU.

AWS European Sovereign Cloud (new in 2026)

On January 15, 2026 AWS launched the European Sovereign Cloud with its first region in Brandenburg, Germany. It is not just another region but physically and legally separated infrastructure: operated by standalone German companies (GmbHs) with EU-resident personnel and the declared goal that data never leaves the EU and cannot be accessed from the US. It is currently the strongest answer to the jurisdiction question in public cloud — aimed at the public sector and regulated industries.

What this means for a typical SMB

For most companies it is enough to have: an EU region + DPA + encryption + documented data flows. That is the standard we set up in every migration.
Regulated industries (finance, healthcare, public sector) should consider sovereign options — the AWS European Sovereign Cloud, or specific Azure services with additional guarantees.
Do not forget third-party SaaS tools — a compliant cloud will not help if your CRM or mailing tool sends data outside the EU without contractual cover.

Pre-migration checklist

Pick an EU region (Frankfurt, Stockholm, Warsaw…).
Sign the DPA and review processing sub-contractors.
Enable encryption at rest and in transit; consider bringing your own keys (BYOK).
Document personal data flows, including support and monitoring.
For sensitive data, consider a sovereign cloud or additional technical guarantees.
