The invention provides a resource management method and system, and the method comprises the steps: obtaining the historical application data of an inner container resource in a preset historical statistical period, the historical application data comprising a historical application specification and the historical application number of container resources of the historical application specification; determining the specification and quantity of pre-scheduled container resources in a future target time period according to the historical application data; and before the target time period starts, pre-scheduling the container resources according to the determined specification and quantity of the pre-scheduled container resources. Historical application data of the container resources is counted. Predictions are made the specification and quantity of container resources which are possibly applied again in a future target time period according to the historical application data. Before the target time period starts, the container resources are scheduled in advance, so that when the to-be-operated task is applied again, the pre-scheduled container resources can be directly used, the task operation time is saved, and the data processing efficiency is improved.
