Efficient data administration with reed - Solomon code
Journal Title: International Journal of Scientific Research and Management - Year 2016, Vol 4, Issue 12
Abstract
Cloud c omputing is a novel computing paradigm which is recognized as an arbitrary to traditional reference technology right to its intrinsic resource - sharing and low - maintenance character i stics. One of the virtually fundamental services offered by CSPs (Cloud Service Providers) is cloud storage. To increasing reliability and efficiency of data storage in the cloud the technique used is replication , but its drawback is data loss and higher space consumption. One way to increase the data reliability and reducing the storage space in the cloud is Erasure Coding. In Erasure Coding , the data is fragmented and further encoded mutually into data pieces and stored in different locations. The arbitrary benefit of the Erasure Coding is that the corrupted data can be absolutely reconstructed into separate information. Erasure code comprise s of two codi ng techniques regenerating code and locally repairable code. Regenerating Code is used for balancing storage space and its ban dwidth. The Locally repairable code is the technique used to overcome the Disk I/O overhead in the Cloud Storage. The Reed - Solom on code stored data into multiple storage node and encode the data into multiple fragments then perform decoding operation to achieve storage cost wit h the same level of fault tolerance and consumed time
