| Renich[m] | Hello. I am looking on information on how to deploy a DCN using kolla-ansible. I'd appreciate any pointers. | 09:44 |
|---|---|---|
| luchaaijer[m] | <Renich[m]> "Hello. I am looking on informati..." <- I do not have any experience with a DCN setup, but from the looks of it a multinode setup with one AZ per site would work. | 11:21 |
| luchaaijer[m] | Networking might be a bit finnicky to get right, but that depends on your setup | 11:21 |
| luchaaijer[m] | Do you have any specific requirements? | 11:22 |

| Renich[m] | For now, the idea is to have a control plane on virtual machines at GCP. Additionally, compute nodes on bare metal at datacenters. | 16:28 |
| Renich[m] | [@luca:utwente.io](https://matrix.to/#/@luca:utwente.io) thank you for answering. :) | 16:28 |
| JayF | Renich[m]: why? | 18:13 |
| JayF | Renich[m]: that seems like a silly architecture, I'm curious what's the value in not self-hosting that control plane | 18:13 |
| Renich[m] | [@_oftc_JayF:matrix.org](https://matrix.to/#/@_oftc_JayF:matrix.org) the intention is to have more than a few computes in several different datacenters | 18:18 |
| JayF | OH! I think I misread the original | 18:19 |
| JayF | I work on Ironic so when I read "compute nodes on bare metal at datacenters" I assumed Ironic | 18:19 |
| JayF | you're just talking about Hypervisors | 18:19 |
| JayF | still a bit strange to me not to self-host the control plane (openstack-on-openstack except in the same cloud, an oroboros architecture so to speak) | 18:20 |
| JayF | but more understandable | 18:20 |
| Renich[m] | JayF: :D | 18:29 |
| Renich[m] | This is a company that wants to sell very specific services based on openstack on several datacenters. | 18:40 |
| Renich[m] | The idea of a centralized controlled plane is just to simplify the architecture and be able to manage everything from a central location. | 18:40 |
| Renich[m] | I know it is not the common openstack paradigm. We are looking for options. | 18:40 |
| Renich[m] | I think this could be considered edge computing or sorts. | 18:40 |
| Renich[m] | I checked out StarlingX and Airship as well. | 18:41 |
| JayF | ah, that makes more sense | 18:45 |
| JayF | like you run and host everything but the nova-computes, which live in the datacenter | 18:46 |
| JayF | I would be very curious how well that would perform with the latency to/from the queue | 18:46 |
| Renich[m] | Indeed. We made a test using wireguard and it wasn't terrible... with a single user running an instance. | 18:47 |
| JayF | I know in Ironic, we have folks who will often run a central control plane to manage remote hardware | 18:50 |
| JayF | in those cases, we usually see folks draw the line between Ironic API and Conductor, having disparate conductor groups in different regions | 18:50 |
| JayF | I'm unsure the shape of similar features in other projects, but I imagine there's some help there | 18:50 |
