yes these are not 1 off servers, these are "worker bee" type servers, so there's lots of them. Therefore if lets say 25 of them are tied to a single master and the master is deleted or corrupted or whatever, and those 25 go down, there are still a couple hundred other of this same server doing its job.
This is in vcenter/vsphere not workstation. these are virtual servers created via a snapshot of the master vm via powercli script.
