Dynamic preparation of a new network environment, and subsequent monitoring thereof is disclosed. It is automatically determined that a new network environment is designated for creation. A subset of computing hosts is identified from a pool of computing hosts for the new network environment. Network provisioning metadata for each computing host is determined. The network provisioning metadata for each computing host includes a communication address of a baseboard management controller that controls the computing host, and authentication credentials that authorize communication with the baseboard management controller. The network provisioning metadata is stored on a storage device in a predetermined format associated with a network environment provisioner.
