> [TN] From DC management perspective, subcloud group was designed for the purpose of orchestrated operation planning/scheduling/execution. For instance, subclouds belonging to a particular group can be patched/upgraded separately from other subclouds in the same DC in order to run a particular version of the custom app(s). There isn't a means to establish a relation between subcloud group and custom applications otherwise.

> [TN] There isn't a dcmanager/system command for this. One would need to write a small script for this custom provisioning.

> 4. Last one - is it possible to run OpenStack in subclouds? Most of the documentation only seems to mention K8s.
> [TN] As OpenStack can run in a StarlingX standalone system, it should run in a subcloud as well. However, there were some issues with OpenStack on StarlingX since the switch to Debian which only got resolved since June this year. 
> There is no support of OpenStack in the system controller. The system controller was designed to monitor and manage the subclouds. It's not meant to run custom apps/workloads that are not for these purposes. Keep in mind that StarlingX subcloud can be a simplex or multi-node with many workers and storage.
