Optimized data migration within OpenStack cloud

摘要

Cloud computing is a collection of computing resources provided with the help of Internet. Cloud has various benefits such as broad area network access; cost reduction, ease of use, time saving, on-demand delivery of its services and all device support which has Internet connection. However, data migration within clouds is a challenging task. This paper proposes a migration approach that provides a secure and optimized way to handling data in large (MB or GB) amount. Compression reduces the total size of a file upto 30-50 percent, which results into efficient statistics and enhanced performance. Encryption results into data confidentiality and data integrity. Thus, this system deals with optimized data Migration and Data Security.
