Logical Architecture

Figure 1 shows the logical architecture. This figure shows the basic BMS components, the relationship between the BMS and other OpenStack services, and the logic flow of applying for a bare metal instance.

A user's requests for applying for bare metal instances are transferred to the Compute service through Compute API and Compute Scheduler. The Compute service uses the ironic virt driver to transfer the request to the BMS. The request is transferred from the Bare Metal API to the Conductor and then to the driver. In this way, the user successfully configures the physical server.

Similar to the Compute service that interacts with various OpenStack services (such as images, networks, and object storage) to provide VM instances, the BMS interacts with the same OpenStack service that requires images, networks, and other resources to provide bare metal instances.
