in my previous job the ratio was 1 openstack guy / 300 prod hv and
~ 50 non prod hypervisors (non prod clouds).

we had 5 different clouds, 2 biggest clouds shared keystone and
glance (same dc, different buildings, almost lan latency). the biggest cloud had 2 regions
(different connectivity on same dc building)

a different team took care of the underlying hw, live migrations (when
necessary but usually escalated to the openstack team) and install the
computes running a single salt stack command. another team developed a
in-house horizon replacement

that job definitively burned me, i'd say that the sweet spot is about
1 person every 200 hv, but if your regions are very similar and you have
control of the whole stack (i didn't) i think 1 person every 300 hv is

we only used nova, neutron (provider networks), glance and keystone.
