I have set ours up like this. One top-level puppet server, hosting the CA, Filebucket, and Dashboard. This uses mod_balancer and mod_proxy to route to...
Three backend puppet masters, handling the production environment manifests One backend puppet server, handling the dev and test environment manifests In addition, we have our departmental Subversion server, which synchs the puppet configuration to the three backend servers every 15min. To make changes, we do this in the test environment, then check it in to subversion and migrate to production, which causes a subsequent synch out to all 3 backend servers within 15min. We can theoretically have any number of backend production servers now, and the load on the frontend is relatively low. The CA must be on a single server, and we also put thefilebucket here to save on storage and make the dashboard work better -- though we could always put the filebucket onto a completely separate server if we so wished. The CA could likewise be farmed out but since its load is negligible theres no point in doing so. The dashboard could also be on a separate server but again it has low CPU requirements. We use DNS to point to the top-level server. Should we wish to have a remote puppet server (to save on bandwidth) then we can set one up with the same synchronisation, but not add it to the balancer group. Maybe make it use a local filebucket, but it can still use the central CA. This setup also allows us to have one dashboard, but still allow separate departments to run their own puppet environment behind the one DNS CNAME if they so wish. Most of the config info was taken from the Puppet book, though it misses out a key configuration item - you need to specify which env var and HTTP header carries the SSL auth information on the backend, unless you keep the CA on the same host.
