Best hardware architecture for OpenStack services [closed]

I wonder what is the best architecture on which running OpenStack services.
In terms of hardware I have 2 powerful servers (that are identical).
If i should think of a solution, I would say:
- first server: controller node
- second server: compute node

But now, where to put Cinder and Swift? I do not have a third node to use.
Should I install it on the Controller node?
I would appreciate your opinion.

Thank you

The documentation has a few good ideas on how to set it up. Most of the docs have you splitting out setup into three different node types. You could have a full install with 3 total nodes. Controller + Network + Compute. It all depends on how you want to configure your system. With a smaller setup, and not a ton of users, you would be fine with the three server setup.

Swift - Could be on the controller since that's where you are running all of your api endpoints. You could install the proxy server on the Controller, then have it connect into a storage server as the backend(preferably multiple servers.)

Cinder - It depends on what backend you are using. I run the api/scheduler on the Controller. I run cinder-volume on the compute node. I'm using cinder with an NFS backend. If you are using LVM and have a lot more space on the compute node to store volumes then you could install cinder-volume on the compute node.
