The new operating system by European provider SUSE delivers new opportunities for European cloud sovereignty—especially in combination with the latest Intel Xeon® 6900 processor generation.
Regulatory requirements in Europe are evolving rapidly—becoming more comprehensive, more specific, and more enforceable. What began with data protection under the General Data Protection Regulation (GDPR) has developed into a broader regulatory framework covering resilience, sovereignty, and control over data and IT supply chains. Recent and upcoming regulations—including the Digital Operational Resilience Act (DORA), the EU Data Act, the EU AI Act, NIS2, eIDAS 2.0, and the Cyber Resilience Act (CRA)—are reshaping expectations for both cloud providers and users.
As a result, cloud platforms are no longer evaluated primarily on cost and performance. In sectors such as public administration, financial services, and healthcare, data sovereignty, trust, transparency, compliance, and strategic independence have become decisive factors. Cloud is no longer just IT—it is becoming sovereign, regulated infrastructure.
One aspect is often overlooked: sovereignty cannot be achieved solely at the platform or infrastructure level. It must extend to the sovereign operating system (OS) layer, the foundation of the digital stack. With SUSE and alternatives such as Ubuntu, organizations can deliberately choose European-based operating system providers.
With the release of SUSE Linux Enterprise Server 16 (SLES 16), available on T Cloud Public since April 2026, this choice becomes strategically more relevant—particularly for sovereign cloud environments in regulated industries.
The collaboration between T-Systems and SUSE reflects a long-standing partnership focused on secure, compliant, and future-proof digital infrastructure. Together, they provide a sovereign cloud foundation that enables organizations to:
This is not a transactional setup—it is designed for long-term digital sovereignty and trust.
SLES 16 introduces capabilities that directly address regulatory and operational requirements in highly regulated sectors and sovereign cloud infrastructures including extended support.
Our long-standing partnership with SUSE allows us to deliver a sovereign cloud platform that meets the real-world needs of government, financial services, and healthcare where trust, compliance, and longevity are non-negotiable.
Daniel Schellhase, Chief Product Manager, T Cloud Public
SLES 16 is the first enterprise Linux distribution to support fully reproducible builds. This allows organizations to cryptographically verify that binaries match their source code. This means: a developer can take the source code, compile it himself/herself, and get the exact same binary that T-Systems provides.
This proves there are no backdoors or code manipulation.
This directly supports compliance with frameworks such as:
Trust is no longer assumed—it becomes a verifiable foundation for digital sovereignty.
SLES 16 reflects SUSE’s commitment to innovation with purpose. Together with T-Systems, we provide customers with a verifiable, sovereign AI-native operating system foundation that strengthens Europe’s digital independence.
Thomas Di Giacomo, Chief Technology and Product Officer, SUSE
Built on a fully open-source foundation, SLES 16 provides transparency and long-term control over system lifecycles—key requirements for sustainable cloud sovereignty. This is particularly relevant for:
It reduces dependency on opaque (“black box”) technologies that can create compliance risks and limit sovereign decision-making.
SLES 16 supports AI workloads within sovereign cloud environments. New agentic AI capabilities (AI that can take actions) allow advanced automation and intelligence. Because the OS is transparent and the data stays within T Cloud Public; the "agents" aren't sending sensitive data to third-party, non-EU clouds. This enables organizations to:
This enables AI adoption while ensuring data sovereignty in the cloud and regulatory compliance.
Sovereignty is important—but without performance, it falls short. Complex AI and encrypted workloads, such as those in confidential computing, require massive compute power. And compute power is not just a matter of the operating system, but also of the underlying hardware.
With the introduction of the Intel Xeon® 6900 processor generation in early 2026, T Cloud Public addresses growing demand for high-performance computing. In combination with SLES 16, the latest CPU generation enables truly sovereign compute power.
This further strengthens T Cloud Public’s position as a platform for demanding, regulated workloads in Europe. As one of the early adopters of this processor generation in Europe, T-Systems continues to combine trusted infrastructure with leading-edge performance. Notably, the combination of SLES 16 and Granite Rapids also delivers highly competitive pricing.
The combination of SLES 16 and next-generation compute is more than a technical upgrade. It represents a sovereign cloud architecture aligned with European digital sovereignty requirements:
For public institutions and regulated industries, this forms a stable and future-proof foundation for European cloud sovereignty. If you’re interested to learn more about SLES 16, check out these resources from SUSE.

Sovereign Cloud: Greater Protection for Europe’s Data
True digital sovereignty is only possible with European clouds – ensuring full control, data protection, and independence.
The next generation of computing: More compute power at lower cost
More computing power at lower costs with new technologies.
With the new generation of Intel® Xeon® processors, T Cloud Public is expanding its general-purpose instances and delivering significantly higher performance at no additional cost. Given the ever-increasing demands on computing power, data processing, and user experience, cloud providers face constant competition.
