A public cloud system includes a cloud storage service apparatus configured to store an object file, and a cloud function service apparatus configured to obtain an objective function, wherein the objective function is data processing logic defined by a tenant for the object file. The cloud storage service apparatus is further configured to, when receiving a download request for the object file from a first client, send the object file to the cloud function service apparatus. The cloud function service apparatus is further configured to run the objective function to process the object file based on the data processing logic, and return a processed file to the cloud storage service apparatus. The cloud storage service apparatus is further configured to send the processed file to the first client.

Public cloud system and related method thereof

A storage client needs to store to-be-written data into a distributed storage system, and storage nodes corresponding to a first data unit assigned for the to-be-written data by a management server are only some nodes in a storage node group. When receiving a status of the first data unit returned by the management server, the storage client may determine quantities of data blocks and parity blocks needing to be generated during EC coding on the to-be-written data. The storage client stores the generated data blocks and parity blocks into some storage nodes designated by the management server in a partition where the first data unit is located. Accordingly, dynamic adjustment of an EC redundancy ratio is implemented, and the management server may exclude some nodes in the partition from a storage range of the to-be-written data based on a requirement, thereby reducing a data storage IO amount.
