[scientific]How are orgs using openstack for research?

One of the answers I'm seeking is whether or not some orgs create shareable configurations for software stacks that might do things like collect data into sinks like that of what amazon is attempting to offer with aws research cloud. The limitation I see with aws is that everything is built specifically with aws systems, like using S3 to store everything. For example, if your output would be better represented as a graph, it would make more sense to use a kafka-orientDB sink that can be reused. Make it a helm chart? I'm not sure. I was told that CERN uses openstack for research, but I have no idea as to what extent or if they contribute anything back. Does anyone know how a research org is using the infrastructure right now?
