(OSBA) is a German non-profit that operates Europe's biggest network of companies and organizations developing, building and using open source software.

The OSB Alliance and the Open Source Business Foundation (OSBF) first announced their intention to merge the two associations to form a single large advocacy group on 18 November 2013.

[27] SCS was integrated as a sub-working group in Gaia-X and further developed by a small team made up of Christian Berendt (CEO OSISM), Dirk Loßack and Kurt Garloff and a growing community.

[29] SCS uses available open source technologies such as Ceph, Prometheus, OpenStack and Kubernetes and performs the automation, configuration, integration and validation of the components in a standardized and certifiable stack.

The project is hosted by MFG in Stuttgart and founded by the German Federal Ministry of Economics and Technology within the Central Innovation Programme SME.
