【摘要】：云计算的快速发展、日益普及使得越来越多的企业将数据放入远程云存储端.然而,针对现在云存储的存在机密性、可用性、完整性方面的问题,公司并不能完全放心地将其内部的机密、关键数据存入云存储端.针对现今单云存储在使用中显露出许多问题,为了提高云存储服务的可用性,提出在多云存储条件下,基于纠删码算法提高数据冗余性,对数据进行分片编码、重组,提高数据安全性与可靠性;提出多云网关存储结构,通过多云网关将数据安全、可靠地存入各个云存储平台,多云网关可适配时下最流行的如百度云、阿里云、亚马逊S3等,为用户提供可无限扩展的安全云存储环境,具有很高的实用价值;设计实现的多云存储网关使用了云存储平台,通过对云平台的使用,将数据分片存入,同时在下载数据时能够对数据分片进行重组;最后证明了纠删码算法的加入对多云存储网关的时间延迟影响不大,同时能提高数据的可用性、降低存储的成本.
[Abstract]:With the rapid development of cloud computing, more and more enterprises put data into remote cloud storage. Companies can't safely store their internal secrets and critical data in cloud storage. In order to improve the availability of cloud storage services, there are many problems with single cloud storage in use today. Under the condition of multi-cloud storage, the data redundancy is improved based on erasure code algorithm, and the data is coded and reorganized to improve the security and reliability of the data. Put forward a cloud gateway storage structure, through the cloud gateway data security, reliable storage of each cloud storage platform, cloud gateway can adapt to the most popular nowadays such as Baidu cloud, Ali cloud, Amazon S3 and so on. It can provide users with an infinitely scalable secure cloud storage environment, which is of high practical value. The design and implementation of the multi-cloud storage gateway uses the cloud storage platform, through the use of the cloud platform, the data can be stored in pieces, and the data can be reorganized when downloading the data. Finally, it is proved that the addition of erasure code algorithm has little effect on the time delay of multi-cloud storage gateway, at the same time, it can improve the availability of data and reduce the cost of storage.
