We had done TripleO deployment with 3 racks several times and it worked fined.

Not only the tool itself but also the help offered by those whose develop and use it. There is a bit of a learning curve however. At the end of the day I think the best solution is the one that works for you and if you have a chance you should try each one to see which is most suitable. I have not tried TripleO, Airship in a bottle did not work out the box, Kolla-Ansible is useful also but gave me fits troubleshooting, and OpenStack-Ansible I mentioned the learning curve. I do not deal with a lot of manual deploying these days but if I was spinning up a public cloud personally I would roll with OpenStack-Ansible On Mon, Dec 17, 2018, 10:47 AM Cody <codeology.lab@gmail.com<mailto:codeology.lab@gmail.com> wrote: Hello stackers, What deployment tools would be of your choice for deploying a public IaaS with an initial size of 200~300 nodes? Would TripleO be suitable for this cluster size? Thank you very much. Wish you all a happy holiday season! Best regards, Cody
