Hi Dave,

I would suggest getting a minimal deployment up and running with each
environment, before making your choice.

single node deployment up and running:

If you also need bare metal provisioning capabilities for your control &
compute nodes, as well as more advanced host configuration, you might
consider Kayobe, which builds on top of Kolla Ansible. Here is a guide to
building up the configuration for a single node deployment:
