The Sovereign Stack in the Public Sector: STACKIT and Codesphere Establish a New Platform Standard

• Digital Sovereignty: STACKIT provides an independent European cloud infrastructure free from US CLOUD Act dependencies.
• As a multi-cloud runtime environment, Codesphere orchestrates flexible and portable workloads. 
• Framework agreements such as the GovTech Framework and the GovTech Multicloud Broker underscore the leading role of the strategic partners.

Bad Friedrichshall, June 10, 2026 – Schwarz Digits, the IT and digital division of the Schwarz Group, and the Karlsruhe-based software scale-up Codesphere are intensifying their strategic cooperation. The goal is to establish a sovereign and interoperable base infrastructure layer for the German public sector. By combining the cloud infrastructure of STACKIT—Schwarz Digits’ cloud provider—which is physically operated in Germany and Austria, with Codesphere’s vendor-neutral deployment technology, a highly secure alternative to global hyperscalers is created. 

Milestone within the ‘Deutschlandplattform’

By awarding the multi-cloud broker framework contract to Germany’s largest IT system house, Bechtle AG, GovTech Deutschland is laying the technical foundation for an interoperable multi-cloud environment. STACKIT provides a native European cloud infrastructure on which specialized administrative processes and modern AI applications can be operated in the future. Technological independence from non-European providers will sustainably strengthen the state’s digital sovereignty.

A key driver of the collaboration between Codesphere and STACKIT is the contract awarded in April 2026 for the central runtime component of the GovTech framework, with a contract volume of up to 30.8 million EUR, which Codesphere won together with the confidential computing specialist enclaive. This component forms the technical foundation for administrative and healthcare applications such as the Deutschlandplattform and MEDI:CUS across all levels of federalism. STACKIT is firmly anchored in this ecosystem as a sovereign infrastructure provider.

“Digital sovereignty is not an option for the public sector, but a strategic necessity and the fundamental prerequisite for the state’s ability to act. Together with Codesphere, we are transforming abstract political guidelines into an immediately accessible, highly secure platform reality. By linking our certified cloud infrastructure with concrete applications, we are establishing a genuine European alternative to global hyperscalers,” says Claudia Alsdorf, Head of Business Development, Schwarz Digits.

“Together, STACKIT and Codesphere cover what the public sector needs: STACKIT provides the certified infrastructure anchored in Germany. We provide the hybrid-capable runtime environment on top of that, including a SaaS application marketplace and agent-based AI functions. Together, we give public authorities true digital sovereignty, from hardware to application. We’ve already proven that this works in the healthcare sector with MEDI:CUS—one of the strictest regulatory environments of all,” says Elias Schneider, CEO of Codesphere.

Technological Synergy Against Vendor Lock-in

The partnership closes a critical gap in the German public sector by combining physical and logical data sovereignty with agile flexibility. While STACKIT provides the sovereign infrastructure layer, Codesphere delivers the vendor-agnostic, confidential 3D-encrypted runtime and deployment layer. This ensures that government agencies remain technology-agnostic and can migrate applications at any time without migration hurdles. The combination aligns with the growing market trend toward modern multi-cloud broker models.
