Abstract: The invention provides a reconciliation system and method based on a hybrid cloud computing platform. The reconciliation system includes: a bill data processing module, processing data from a public cloud billing API or downloaded bill detailed files; a data monitoring processing module, processing the data collected from the resource pool of the computing management system resource pool and task resource requested; a task data processing module obtaining and processing task data from the task database of the computing scheduling system, and calculating the core hours that the tasks consumed; a statistical alarm module combining the resource data table obtained by the above three modules to obtain the utilization ratio and difference range of the computing task packing can realize the reconciliation alarm and prediction for task core hours. The computing power demand for a large number of existing tasks can be used to guide the purchase of computing power in the future.
