I think a bigger business case is virtual machine hosting, say one of these is maxed out (8 Xeons with 56 cores ie 448 cores and 32tb of memory), say it's divided into a 1000 machines you can run each VM with 40% cpu utilization and 3gb of memory, considering many VM offerings have less RAM (and add a bit of overselling on top of it with regards to CPU) it could probably house over 2000 VM's.

You can do that more cheaply with separate machines. The use case for this mega one really is monolothic DB or server.
