What is the Operational Concept of the bwCloud Region Freiburg?[faq_concept_1]

The focus of the bwCloud Freiburg region is on providing an environment for re-deployable services.

This means that services do not depend on the state of a VM, but can be "pushed" onto the cloud on-demand and started there. Relevant data should be stored on secure storage areas and not on the cloud's own storage (in the form of volumes or images).

One option for outsourcing to/using external storage is to mount appropriate NFS or object storage resources. Frequent backups of data to appropriate secure storage systems are also recommended.
