Having a multi-node scenario is something in our roadmap:

In Tokyo Summit we wanted to start looking at multi-node jobs where
compute services would be separated.
Unfortunately, nothing is really in place at the moment on our side.

We're currently having design discussions around our integration jobs:

Feel free to participate and eventually contribute back.

Regarding your need, Matt is right.
We don't "cook" for you, just because our Puppet modules are so flexible
that you can define your own architecture for any OpenStack service -
which is not something you can entirely do with OpenStack Ansible as a
The manifests on puppet-openstack-integration are useful for our
upstream CI but also for all-in-one testing. They don't aim for
production deployments, and we expect our community skilled enough in
Puppet to know how to write a manifest.
Though we're doing our best to provide some documentation and examples.
For example in puppet-nova:

There are 2 kind of Puppet OpenStack users at this time:

* Installer folks: they take our modules and write an interface to
compose layers with different backends, drivers, configurations support.
The 2 most popular installers using our modules are Fuel & TripleO.

* People who compose their own manifests (that's your case right now I
guess?) - You'll need to take time to read our modules/manifests and
understand how we split services and configure them.
I can provide you an example at how we compose in TripleO:

I hope all of this helps, and feel free to bring any feedback or ask for
more informations,

Let me clear this sentence to avoid any confusion:
https://forge.puppetlabs.com/puppetlabs/openstack is a Puppet module
that is now outdated and I'm not sure it's maintained anymore.
It was an effort out of OpenStack community, led by Puppetlabs.
