Abstract
Technologies for managing fault recovery in a cloud computing environment may be used after faults of various sizes, including faults which put total functioning capacity below subscribed capacity. Computing services have repair priorities. A fault recovery manager selects a higher priority service whose capacity is below a minimum availability, and chooses a lower priority service still above its minimal availability, and reassigns capacity from the lower priority service to the higher priority service without depriving the lower priority service of operability. Capacity reassignment continues at least until the higher priority service is at or above minimal availability, or the lower priority service is at minimal availability. Lower priority services may also be terminated entirely to free up resources for higher priority services. New deployments may be prevented until all services are at or above minimal availability. Spare capacity may be reserved against demand fluctuations or further faults.
