Is a AIO or multi host setup?

I have found places in openstack ansible that bypass the proxy server variables.
My memory was is that it was using systemd to fetch files in certain
cases and that systemd did not honor proxy variables.
I have ended up using a secondary proxy on the deployment host along
with a NAT setup
on the deployment host that made sure to send external requests to the proxy.
