Undercloud
Undercloud is a component of the OpenStack cloud computing platform that serves as a management and deployment layer for the main OpenStack cloud infrastructure, known as the Overcloud. It provides a set of tools and services, such as Ironic for bare metal provisioning and TripleO (OpenStack on OpenStack), to automate the installation, configuration, and lifecycle management of the Overcloud nodes. Essentially, it acts as a foundation that orchestrates the deployment and scaling of the production cloud environment.
Developers should learn and use Undercloud when working with OpenStack deployments, particularly in enterprise or large-scale cloud environments where automated, repeatable infrastructure management is critical. It is essential for scenarios requiring bare metal provisioning, complex multi-node setups, or when using TripleO to deploy and manage OpenStack clouds, as it simplifies the operational overhead and ensures consistency across deployments.
