I know I am not an operator, but to respond on this particular point
related to the Kolla question above, I think the team size could be very
small and still effective.  You would want 24 hour coverage of your data
center, and a backup individual, which puts the IC list at 4 people. (3 8
hour shifts + 1 backup in case of illness/etc).  Expect for these folks to
require other work, as once Kolla is deployed there isn't a whole lot to
do.  A 64 node cluster is deployable by one individual in 1-2 hours once
the gear has been racked.  Realistically if you plan to deploy Kolla I'd
expect that individual to want to train for 3-6 weeks deploying over and
over to get a feel for the Kolla workflow.  Try it, I suspect you will
like it :)

If you had less rigorous constraints around availability then I'd expect
Godaddy to have, a Kolla deployment could likely be managed with as little
as half a person or less.  Everything including upgrades is automated.
