Techniques for server movement control are described. A capacity library service (CLS) can manage which hosts in a provider network can be taken in and out of production. The CLS may also control which entities may remove hosts from production and under what conditions the hosts may be removed from production. In some embodiments, the CLS can execute various workflows to manage checkout and check-in of hosts. Workflows may also be used to manage hosts while they are out of production to manage state transitions (e.g., in production, in testing, in reserve, etc.) based on current host fleet capacity and checkout rules.

A method for removing computing assets from service in a provider network includes receiving, from a requestor, identification for selected ones of the computing assets requested to be removed from service. Each of the computing assets is a computing device or a slot of a computing device. A pool in which each of the computing assets requested to be removed from service is located is identified. For each identified pool: which of the computing assets requested to be removed from service is approved for removal from service is determined based on a number of resource instances available for allocation to users after the computing devices are removed from service exceeding a predetermined number of resource instances. The requestor is notified as to which of the computing assets is approved for removal from service.
