Hi Chris, That was a lengthy writeup, thanks :). I think the first step is to think in terms of (container/VM) provisioning. Then build that up towards orchestration and workflows. There is some overlap with the HPC working group, but I think we ought to have one on orchestration/provisining/work flows. I am quite keen to have something in place in the coming year. I.e., roll out firing up of software combinations in isolated environments. Let's keep discussing and build up a web page for that.
My first provisioning step is to start up a Guix container on a server somewhere through a REST API and fire up a script that can run in the container. Pj.
