Hi all, There is no recommendation in large-scale doc about how to deploy OpenStack. Most of the solutions that were given previously should be great. What I'd like to add in the equation is the ability to modify the code behind your deployment tool because, at some point for large scale, you will definitely need to do some downstream changes to handle your specific use case. E.G. we are a public cloud provider and we do care about the uptime of our API. On the other hand, some large scale private cloud will maybe care more about the computes responsivness. This give some constraints that you can use to chose your way. Take also into consideration your team members. If you are used to ansible, then maybe a solution relying on that would be a better fit. If you are used about k8s, them k8s based solution could be your option. Regards, Arnaud On 04.09.24 - 10:04, Michał Nasiadka wrote:

Hi Thamanna,

Last but not least - here’s a link to Deploy Guide for 2024.1 - https://docs.openstack.org/2024.1/deploy/ You can see two deployment tools that are listed there - Kolla/Kolla-Ansible and OpenStack-Ansible

For Large Scale deployments you should also have a look in the Large Scale SIG docs - https://docs.openstack.org/large-scale/

I don’t know if there’s a tool that is the best choice for production - all of the known deployment tools in OpenStack ecosystem are a good choice for the community of operators (every one of them for a different reason, if it’s LXC containers if you want to use, or Docker/Podman, or Kubernetes) - it’s rather up to you to choose a project/community that you’d like to be a part of.

I’m pretty sure whatever tool you would choose - it’s a good fit for production, as long as the community is actively fixing bugs and adding new features - and is a welcoming community that you’d like to be part of (because that’s the ultimate way that community will grow - if you’ll be an active contributor to the chosen deployment project). Contributions does not mean submitting code - being around, raising bugs, helping the community in any other way to grow - that’s also extremely valuable from a project perspective.

Hope that helps,

Michal Nasiadka

Hello OpenStack Community,

We are preparing for a large-scale OpenStack deployment in production and currently use Kolla Ansible. Before proceeding, we want to know if Kolla Ansible is the best choice for production or if there are better alternatives for large-scale deployments.

Any recommendations or insights on the best deployment methods for production environments would be greatly appreciated.

Thank you!
