MLCS: a cloud storage architecture based on metadata layer

摘要

At present, the design of architecture is the primary problem for cloud storage. GFS has the problems of single point of failure and performance bottleneck. This paper proposed a cloud storage architecture based on metadata layer (MLCS), for the goal of improving the service performance and reliability of the system. The visit load is shared by metadata layer and the time of searching and analyzing metadata is reduced by dual harsh. The improvement of MLCS on reliability, scale, and service performance was verified by experiment and theoretical analysis.
