A resource scheduling method including sending, by a first cluster instance, to a second cluster instance a resource borrowing request if available resources owned by the first cluster instance is less than a threshold; receiving borrowable resources information returned by the second cluster instance, wherein the borrowable resources information represents borrowable data server resources in the second cluster instance; and acquiring, by the first cluster instance, the borrowable data server resources for data processing. The techniques of the present disclosure realize resource reuse between cluster instances, make full use of the resources of each cluster instance, and improve the resource utilization rates of the clusters.
