Cloud disk scheduling method and device based on elastic block storage service and storage medium

The embodiment of the invention provides a cloud disk scheduling method and device based on an elastic block storage service and a storage medium. Historical cloud disk use condition information of a user to which a to-be-created cloud disk belongs and current storage condition information of each storage cluster are acquired; predicting the prediction compression rate of different storage clusters in the case of creating the to-be-created cloud disk to the different storage clusters; and determining a target storage cluster from the storage clusters according to the predicted compression ratios of the different storage clusters, so that the difference between the compression ratios of all the storage clusters is minimum after the to-be-created cloud disk is created to the target storage cluster. When the cloud disk is created, the problem of storage cluster compression ratio balance is considered, and a proper target storage cluster is selected for the to-be-created cloud disk, so that the compression ratio
