About SCS

Working together for digital sovereignty in the cloud

Sovereign Cloud Stack (SCS) is a European initiative that creates an open, transparent and vendor-neutral cloud ecosystem that guarantees sovereignty. The emphasis is on real freedom of choice. SCS is based on certifiable standards, a modular software stack and practical knowledge transfer.

The certifiable SCS standards are developed openly, collaboratively and in line with requirements. In a continuous process, the community creates a reliable framework for secure cloud infrastructures.

The modular software stack provides open source implementations and thus shows how a sovereign cloud works in practice. The software stack is based on proven projects that have already been used to build certified environments, such as OpenStack and Kubernetes, is developed by the community and offers a turnkey basis for your own cloud infrastructures with the modules.

A clear central goal of SCS is to promote skills and knowledge. Open collaboration, documentation and exchange create a culture in which skills, experience and innovation are shared.
