new cloud site installation/configuration architecture question

I have two bare-metal machines (24 cores each). Both have "Ubuntu 16.04.1 LTS" on them. My objective is to install OpenStack on both of these machines, so that I can virtualize them and manage them with OpenStack to allocated and manage VM's for production use.
I didn't have any OpenStack experience prior to this. I installed DevStack on machine_1, and was able to get to the "dashboard" -- but upon further reading, I found that I DevStack is not supported for production use (if your machine reboots, devstack doesn't restart and you have to reinitialize it; among other limitations, I'm guessing).

Questions: 1) So what do I do now? how can I leverage the "devstack" installed software (or do I?) - should I reinstall all my software?

2) Also, what is a good configuration for moving forward for the two machines; and given that if I add another baremetal machine to create even more computing power, what do I install on each of the new machines?

3) Can anyone point me to the "architectural" picture of what I'm trying to do, that shows all the software that would be needed to run on my bare-metal machines (I'm imagining, machine_1 has all the configuration info, mysql..etc. & machines 2 & 3 would just be additional compute-nodes farms). I'm not worried about HA.

I appreciate your help!

Thanks, Joel

Question 1: Don't use devstack. Reinstall. For the rest, perhaps you should start by reading the architecture guide and go through the install guide to learn, then pick a distro to install. In my very humble opinion, one of your hosts should be controller, and both should be compute.
