You are asked to provision a bare-metal server using OpenStack. Which service is required to satisfy this requirement?

OpenStack is an open-source cloud computing platform that provides various services for managing

compute, storage, and networking resources. To provision a bare-metal server in OpenStack, the

Ironic service is required. Let’s analyze each option:

A . Ironic

Correct: OpenStack Ironic is a bare-metal provisioning service that allows you to manage and

provision physical servers as if they were virtual machines. It automates tasks such as hardware

discovery, configuration, and deployment of operating systems on bare-metal servers.

B . Zun

Incorrect: OpenStack Zun is a container service that manages the lifecycle of containers. It is

unrelated to bare-metal provisioning.

C . Trove

Incorrect: OpenStack Trove is a Database as a Service (DBaaS) solution that provides managed

database instances. It does not handle bare-metal provisioning.

D . Magnum

Incorrect: OpenStack Magnum is a container orchestration service that supports Kubernetes, Docker

Swarm, and other container orchestration engines. It is focused on containerized workloads, not

bare-metal servers.

Why Ironic?

Purpose-Built for Bare-Metal: Ironic is specifically designed to provision and manage bare-metal

servers, making it the correct choice for this requirement.

Automation: Ironic automates the entire bare-metal provisioning process, including hardware

discovery, configuration, and OS deployment.

JNCIA Cloud Reference:

The JNCIA-Cloud certification covers OpenStack as part of its cloud infrastructure curriculum.

Understanding OpenStack services like Ironic is essential for managing bare-metal and virtualized

environments in cloud deployments.

For example, Juniper Contrail integrates with OpenStack to provide networking and security for both

virtualized and bare-metal workloads. Proficiency with OpenStack services ensures efficient

management of diverse cloud resources.
