Controlled automatic healing of data-center services

Subject matter described herein is directed to reallocating an application component from a faulty data-center resource to a non-faulty data-center resource. Background monitors identify data-center resources that are faulty and schedule migration of application components from the faulty data-center resources to non-faulty data-center resources. Migration is carried out in an automatic manner that allows an application to remain available. Thresholds are in place to control a rate of migration, as well as, detect when resource failure might be resulting from data-center-wide processes or from an application failure.
