Hello. I have read about kolla ansible multi regions. Can i ask that do we need 2 deployment host? And can we use 3 controller each region? I searched on Internet, I see that controller just sit on region one only? Please advise. Thank you. -------------- next part -------------- An HTML attachment was scrubbed...
