Bare metal plays a variety of roles in the modern data center. Essentially, legacy hardware, core business apps like ERP, and specific apps required by an organization often drive the requirement for bare-metal workloads in the data center. This is down to the fact that bare-metal servers are a good fit for high-performance computing (HPC) applications because they are free from normal virtualization overhead.
What Is Bare Metal?
Bare metal describes a computer framework that does not have a base operating system (OS) or installed applications. It is a computer's hardware assembly, structure, and components that are installed with either the firmware or basic input/output system (BIOS) software utility or no software at all.
