Improved data distribution strategy for cloud storage system

Considering massive scale of cloud storage solutions,the traditional data distribution strategy confronts challenges to improve scalability and flexibility.This paper proposed an efficient data distribution strategy.Based on consistent hashing algorithm,the strategy introduced the virtualization technology,and employed virtual node to improve load balance.Moreover,the strategy used a new capacity-aware method to improve the performance of the cloud storage system.The evaluation experiments demonstrate that the proposed data distribution strategy improves system performance in both homogeneous and heterogeneous distributed storage architectures.
