Sovereign Cloud Stack

One platform — standardized, built and operated by many.

OSISM was founded in 2016 as Betacloud Solutions. With the goal of implementing a public cloud, the Betacloud, based on OpenStack. The outcome of these activities was the OSISM framework. OSISM has since been used by a large number of customers to implement on-premise cloud infrastructures. Meanwhile, OSISM is the core business and is being further developed as part of the Sovereign Cloud Stacks project.
