UPGRADING AN ELASTIC COMPUTING CLOUD SYSTEM |
摘要 |
A server of an elastic computing cloud system includes a block device driver apparatus and at least a block device service apparatus. The server implements a hot deployment for a storage service, such that an upgrade of the storage service may be performed without interrupting the storage service. The block device driver apparatus maintains a waiting queue and a pending queue for each storage service. In response to determining a storage service will perform an upgrade, the block device driver apparatus stops processing data write/read requests that are maintained in the pending queue for the service, and puts the data write/read requests that are currently processed in the pending queue back to the waiting queue for re-dispatching, thus realizing completion of processing the upgrade of the storage service in the elastic computing cloud system without interrupting the storage service. |
