Abstract

Abstract:

The development of cloud storage service is one of the key elements to cloud data technology. New data storage architecture for cloud storage service based file systems was proposed. And the design and implementation of cloud storage-backed file system based on the architecture (CSFS) was described. The development and deployment costs are reduced by utilizing free email service. The efficiency and scalability are increased by separated management of metadata, data block, distributed storage and cloud data prefetching. Experiments show that the optimization method improves the read and write performance of the system effectively.

Key words: cloud storage, file system, metadata management, prefetching, incremental encryption
