STORAGE SERVER FORSECURE AND PERFORMANT EXECUTION OF USER CODE IN A DATA CENTER STORAGE

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.
