Technology for monitoring all resources and services of a distributed computing environment to collect and store information technology (IT) infrastructure resources, task resource usage metrics, and idle times of the environment. A system management task, both manually created by administrators and automatically scheduled, is queued on a management queue to be processed at a later time. When the system management task is removed from the queue, resources required to execute the activity of the distributed computing environment are then requested. The task is authorized to execute if the requested resources and time to complete the activity are available. The resources are then secured and the system management task executed in the distributed computing environment.
