What is bare metal environment?
A bare metal environment is a type of virtualization environment in which the virtualization hypervisor is installed directly and executed by the hardware. It eliminates the need for a host operating system by directly interfacing with the underlying hardware to reach VM specific processes.
A bare metal environment can also be referred to as a tier 1 environment.
A bare metal environment is typically created using bare metal hypervisors that do not require the support of a host operating system. The hypervisors are installed on the hard disk and can create virtual machines as in a typical virtualized environment. Each virtual machine has a separate guest operating system and share of memory, computing power and hard disk space. The hypervisor has its own device drivers and interacts directly with any component for any I / O, processing or operating system-specific task.
