We saw this one iteration back with VMWare. Once it became easy to spin up a VM without getting a PO for a server and finding rack space, the number of "servers" in the org exploded. And of course we lost track of what they all did, and who they belonged to... but there was actually a healthy ecosystem of tools built for (and by) VMWare to manage this situation. The cloud providers seem incentivised to make tracking real costs as difficult as possible. At least with VMWare once you paid for it, it was yours.
