End of bwCloud maintenance 30.03.2023

The maintenance of the bwCloud Freiburg has been successfully completed.

In the course of the maintenance, the following changes took place:

* Splitting the cloud networks into two parts.

* Updating the compute nodes

* Updating the API nodes

Users from the Freiburg region have been activated again.

The maintenance is in line with our preparations for our future operating concept.

In order to test the different options and to push developments in the context of projects, it is planned that the bwCloud Freiburg will consist of two independent computer networks/computer clusters in the near future: Productive- and Experimental-bwCloud Freiburg.

On the one hand, the current Productive bwCloud for all standard needs with a focus on stability. This corresponds to what we are used to and will cover the needs of most users.

On the other hand, there will be an experimental bwCloud for testing new features, e.g. for integrating GPUs or testing long-term scheduling, as well as for ongoing student work. Furthermore, this is also the computer cluster on which the next Productive bwCloud will be built.

Notes on the cloud operating model

The focus of the bwCloud should be on 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 possibility is to mount corresponding NFS or object storage resources or to regularly back up the data to correspondingly secure storage systems.
