Bare metal, white machine, physical machine
This: The main reason for the frequency of use of bare metal is that the frequency of use of the relative term virtual machine is increasing. Before cloudification, the concept of bare metal should not be applied very frequently, because in the subconscious mind of everyone, hardware is a computer machine, and they will not specifically say that this is a bare metal machine, because of the relative concept Not very popular yet.
In the era when cloud platforms are prevalent, the concept that is opposite to cloud (to show the difference) will be used more frequently, which can also be regarded as: two words that are opposed to each other, and a kind of inertial force that is entangled with each other.

Some obvious caveats apply when using a VM for VPP since its performance will never match that of bare metal; if your work is timing or performance sensitive, consider using bare metal in addition or instead of the VM.
