摘要
电子文件迁移要符合代价低、执行快、兼容性强等要求,云计算下构建迁移模型需体现文件的访问频率。借助云计算的海量存储、个性化应用,高共享性特征,设计概论迁移触发函数,可以减少访问文件云端存储负载性能的负面作用,减少资源开销。试验结果显示,云计算环境下的电子文件迁移模型,在处理时间、吞吐率方面优于传统磁盘冷却法18%以上。
The migration of electronic documents should meet the needs of low cost,fast execution and strong compatibility.The migration model in cloud computing environment should reflect the frequency of file access.With the help of massive storage of cloud computing,personalized applications,high sharing features,an overview migration trigger function is designed.The function can reduce the negative effect of accessing the file cloud storage load performance,and reduce the resource overhead.The experimental results show that the electronic file migration model in cloud computing environment is superior to the conventional disk cooling method in handling time,and the throughput rate is larger more than 18%.
