Core architecture design of CMS in cluster environment

By comparing non-cluster environment with cluster environment, an architecture design of the core part of CMS (publish and view news, upload and download news accessory) is put forward in this paper, which is suitable for cluster environment and is the improvement of the architecture design for non-cluster environment. The problem that files can not be normally updated, which occurs when the architecture for non-cluster environment is moved to cluster environment, is solved by restoring files into database servers and restoring copies of files into application servers. Finally, the performance of the architecture design is greatly improved because of caching mechanism.
