Also not necessary a no-brainer on cost:

"But where labor efficiency is greater than [400 VMs per engineer], OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options."

This study does ignore the services supplied on top of basic compute, however.

Disregarding cost (haha) is OpenStack actually attractive to use? I was under the impression it was a bit of a bear to deploy and operate (my previous employer gave up, though I strongly suspect the project was never resourced properly in the first place).

Depends on what you mean by "attractive"...

Are any cloud providers UIs good? OpenStack provides decent APIs, and a usable UI. and I much prefer the CLIs OpenStack has to AWSs.
