Sovereign Stack: AWS, Suse and SAP for Europe

European CIOs (Chief Information Officers) in strictly regulated sectors have so far been faced with a major dilemma: either move to the public cloud to innovate or move to the private cloud.
remain on-premises for compliance with strict sovereignty laws. With the launch of AWS
European Sovereign Cloud in January 2026 and the support of Suse and SAP, this conflict has been resolved.

Physically separate cloud infrastructure 

The first region of the AWS European Sovereign Cloud is in operation in Brandenburg, Germany. In contrast to previous offerings, this cloud is physically and logically separate from existing AWS regions. 

Operations are carried out exclusively by personnel based in the EU. All metadata and customer data remain within the European Union, supported by independent billing and identity systems.

This gives customers access to the full portfolio of cloud and AI services while complying with the strictest sovereignty requirements.

Sovereign stack for SAP users 

Infrastructure alone does not drive business - it's the applications. Suse acts as a launch partner and provides the „Suse Linux Enterprise Server (SLES) for SAP Applications“ directly in the AWS Marketplace. Since the majority of SAP Hana implementations run on Suse, the Sovereign Cloud Stack is ready for business-critical workloads from day one.

Suse relies on a pure open source basis,
to eliminate supply chain risks and guarantee technological independence. The
CC/EAL4+ certification offers maximum security and autonomy. This simplifies compliance with regulations such as GDPR, NIS2 and DORA. Also new in SLES for SAP 16 are „reproducible builds“, which enable transparent auditability. SAP also confirms that organizations can now operate business-critical workloads and AI securely under European governance.

Innovation without compromise 

For SAP customers, the argument of postponing S/4 Hana migrations due to regulatory hurdles no longer applies. It is no longer necessary to build your own data center in order to be compliant. Companies can now implement a clean-core strategy on AWS and at the same time gain agility through generative AI services such as Amazon Bedrock - with full protection of data sovereignty.

What does this mean for SAP customers?

Compliance as a driver of innovation: teams can now develop extensions supported by artificial intelligence directly alongside SAP core data without it leaving the EU - for example, for fraud detection in finance or for analyzing patient records.

Operational resilience at the click of a mouse: high-availability (HA) clusters for SAP Hana can be efficiently deployed via preconfigured environments in the AWS Marketplace. Functions such as live patching ensure 24/7 operation and shift OS management from investments in intensive CapEx projects to flexible OpEx models.

How can legacy technology be disposed of? Migration to the sovereign cloud should be used as an opportunity for selective data transformation. Only relevant, active data moves to the new S/4 Hana instance. This leaves technical ballast behind, while the new system is compliant, secure and upgradeable from birth.
