bwCloud-OS wiki

The cloud is jointly operated by the universities of Freiburg, Karlsruhe, Mannheim, and Ulm, and is available for use by all participating educational institutions throughout the state.

General information about the bwCloud-OS service and the bwCloud3 project is available on our website. Technical support is available on the support portal.
