AAP installation on a single node

HI I am looking to install AAP on a single node,
DB and Controller on the same RHEL node.
also, I have read that hub can not be installed on the same node as,
the controller.
and I am looking at the hybrid cloud console I have access to it but is it included as part of my subscription I have a subscription for AAP.
automation hub is this a SAAS or does it need to be installed on another node?
sorry for this long-winded question I thought I would ask here as someone may have had similar questions like these before.

any advice would be appreciated just to understand :)
