First and foremost I just realized that I forgot to tag kolla and openstack-helm
in the subject so, I apologize. I'm glad the subject was catchy enough to get
your attention.

Just want to raise here what I just mentioned on IRC:

It's late in EU so I shouldn't be here right now but, I do want to point out
that, as usual, I asked for feedback and clarifications from everyone in this

I'm not trying to re-invent the wheel. What's in my original email is my
conclusion based on a research I did across the different tools there are. I
can, of course, be wrong and I'd like you all to help us by providing feedback.

I'm not expecting sales pitches but I'd love to have a more technical discussion
on how we can, hopefully, make this work.

It's just a PoC, don't take the implementation as definitive.

Let's talk, that's the whole point of this thread.
