Provided is a resource management method and system, and a computer storage medium. The method comprises: determining tasks within a task group and a preset task time corresponding to each task within the task group (S110); determining whether the sum of the preset task times corresponding to all the tasks in the task group is less than a preset time threshold (S120); if yes, then determining the resource usage time quota of the task group to be the sum of the preset task times corresponding to all the tasks in the task group (S130); if no, then determining the resource usage time quota of the task group to be the time threshold (S140); determining the allowable run time per unit time for each task in the task group (S150); within unit time, when each task in the task group is outside of the corresponding run period, the respective task in the task group are respectively entered into a waiting state (S160).
