Abstract: A data center is provided which comprises one or more storage servers, and at least one of a compute server and a frontend server. A storage server for a data center is provided. The storage server is configured to obtain a data request, which is indicative of target data and a user-defined code. Instead of providing the target data to a requestor, the storage server is configured to obtain the target data and to execute the user-defined code on its own. Since the user-defined code may be malicious, the storage server is configured to execute the user-defined code in an isolated execution environment or a sandbox, such as a virtual machine or a container. In this way, data processing in the data center can be more efficient due to applying the near-data processing paradigm, while the security level can still be maintained.

Abstract: 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.

Abstract: In the website system of the application, when a client accesses a page of a website, a web server obtains an initial URL of a content file included in the to-be-accessed page and a version parameter of a current version of the website, generates a current URL of the content file, and adds the version parameter to a search part of the current URL of the content file, so that the client can obtain the content file from the web server according to the current URL. During version upgrade of the website, a developer does not need to change a path to a content file, does not need to manually change a URL of the content file, and does not need to update a name of the content file either. This improves website upgrading efficiency.
