Hi,
Are you looking to setup an Opensource Openstack or a specific vendor versions like Redhat Openstack or Suse openstack? I prefer to use Centos and use the opensource openstack components. By the way, do u have hardware or planning to implement on cloud virtual machines ?
To setup a minimum, you need a control node and compute node. I did setup one for my learning purpose with Redhat Openstack.
Happy to discuss further - Thank you
