Sure you can. Just hire a bare metal machine or a whole-machine VM. Those
things exist at AWS and GCP.
For something like $200/hr.
Note you can get a full bare metal machine for 750€/yr at Hetzner.de. But it
comes with sysadmin cost, since it's *just* the machine.
PS: Intel has a technology called RDT that is meant to allow Cloud Service
Providers to offer solutions that isolate one tenant from another's noisy
access, including cache thrashing and memory bandwidth. I don't know if the
CSPs sell fractions of a full machine but guaranteeing performance, using RDT.
