【摘要】：云計算的快速發(fā)展、日益普及使得越來越多的企業(yè)將數(shù)據(jù)放入遠程云存儲端.然而,針對現(xiàn)在云存儲的存在機密性、可用性、完整性方面的問題,公司并不能完全放心地將其內(nèi)部的機密、關鍵數(shù)據(jù)存入云存儲端.針對現(xiàn)今單云存儲在使用中顯露出許多問題,為了提高云存儲服務的可用性,提出在多云存儲條件下,基于糾刪碼算法提高數(shù)據(jù)冗余性,對數(shù)據(jù)進行分片編碼、重組,提高數(shù)據(jù)安全性與可靠性;提出多云網(wǎng)關存儲結構,通過多云網(wǎng)關將數(shù)據(jù)安全、可靠地存入各個云存儲平臺,多云網(wǎng)關可適配時下最流行的如百度云、阿里云、亞馬遜S3等,為用戶提供可無限擴展的安全云存儲環(huán)境,具有很高的實用價值;設計實現(xiàn)的多云存儲網(wǎng)關使用了云存儲平臺,通過對云平臺的使用,將數(shù)據(jù)分片存入,同時在下載數(shù)據(jù)時能夠對數(shù)據(jù)分片進行重組;最后證明了糾刪碼算法的加入對多云存儲網(wǎng)關的時間延遲影響不大,同時能提高數(shù)據(jù)的可用性、降低存儲的成本.
[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.
