In our case, 2 might be a bit limiting and push us to using virtualization on the boxes instead of treating them as bare metal deployments. A "basic" Foreman/Katello topology would be a server and a capsule with 1 or more clients (with 1 being a generally OK test case). The difference is that it takes ~1-1.5 hours to do a full successful deployment, installation and test run currently. I don't mind switching to virtualization as this is how we test locally and do development, however, it does change the workflow and scripts which would need accounting for. Do you have an idea of the average time to live for provisioned boxes? And how many at any given time tend to be provisioned from the pool?
