Design and implementation of distributed algorithm for cloud data center operating system copy

Yeming Zhangmingfujang

This paper introduces the replica distribution algorithm in cloud Data center operating system (clouds 0s), which is used to solve the problem of replica distribution in cloud storage environment, transforms the storage node selection problem into a multiple index decision problem (MCDM), and uses topsis to solve it. The algorithm can make full use of many kinds of detection data in cloud computing environment, and combine the flexible weight allocation method to adapt to most cloud storage environment. The simulation results show that the cloud 0s algorithm is superior to traditional least and Ran-dora algorithms in load balancing and replica creation time.
