OSISM provides cloud infrastructure for enterprises, service providers & ISVs

Discover more about OSISM

OSISM is a powerful deployment and lifecycle management framework for software-defined infrastructures such as OpenStack, Proxmox VE and Ceph, and the services they require, such as a RabbitMQ broker or a MariaDB Galera cluster. Monitoring, log aggregation and high availability are also key areas of focus. OpenStack and Proxmox VE provide a proven and reliable foundation for platforms such as GitLab CI, Kubernetes, Cloud Foundry and OpenShift.

OSISM is used by the Sovereign Cloud Stack (SCS) to manage core infrastructure services. OSISM is an integral part of one of the first Gaia-X hosters as the basis for pluscloud open from the German cloud service provider PlusServer in Cologne.
