====== Bare-Metal Infrastructure ======

[[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]

===== Discussion =====

Bare-Metal Infrastructure consists of physical computing resources on which an operating system, platform, or workload operates without an intervening server-virtualization hypervisor.

Bare-Metal Infrastructure can include:

  * Physical servers
  * Processors and memory
  * Local and attached storage
  * Physical network interfaces
  * Network switches and supporting network services
  * Hardware security devices
  * Accelerators and specialized processing devices
  * Firmware and hardware-management interfaces

Bare-Metal Infrastructure can exist within an organization-controlled data center, colocation facility, edge location, laboratory, secure facility, or Cloud Provider environment.

Within Crucible, Bare-Metal Infrastructure can serve as a [[dido:99_annexes:annex-b-terms-and-definitions:d:deployment_platform|Deployment Platform]] on which Crucible provisions operating systems, platform software, security controls, compliance controls, and supporting services directly onto physical computing resources.

===== Definition =====

*physical computing infrastructure on which an operating system, platform, or workload operates without an intervening server-virtualization hypervisor*

===== Note =====

Bare-Metal Infrastructure does not necessarily mean infrastructure located on premises. A Cloud Provider can provide dedicated bare-metal servers as a managed or on-demand service.

The absence of a server-virtualization hypervisor does not prohibit container runtimes, operating-system virtualization, orchestration platforms, hardware-management controllers, or other software layers.

Bare-Metal Infrastructure can host Red Hat OpenShift Container Platform or another platform layer.

===== Example =====

Crucible provisions an approved operating-system image, network configuration, storage configuration, security controls, compliance controls, and platform services directly onto a physical server without first creating a virtual machine.
