Sovereign Cloud Stack

The Sovereign Cloud Stack (SCS) is a European initiative that creates an open, transparent and vendor-neutral cloud ecosystem that ensures sovereignty and interoperability. The focus is on cloud technology with genuine freedom of choice: legally secure, interoperable, vendor-independent and cloud-native.

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 an open-source reference implementation, demonstrating how a sovereign cloud works in practice. The software stack is based on proven projects such as OpenStack and Kubernetes, is developed by the community and, with its reference implementation, offers a turnkey basis for your own cloud infrastructures.

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.

SCS Certificates

The standard for open cloud infrastructures

SCS Certificates stand for trust, quality and digital sovereignty. They set standards for open cloud infrastructures and highlight which providers and integrators meet the highest standards for security, interoperability and independence.
