A Survey on Data Replication Technologies in Data Grid

Sun Hai

Abstract

Replication technologies have been widely applied in data grid systems to improve the performance of grid applications. Compared with those technoloies applied in distributed database, distributed object computing and mo- bile computing systems, the replication technologies applied in data grid systems hold many unique characteristics. In this paper, replication in data grid systems is summarized as 6 aspects including Replica Creating, Data Transferring, Replica Deleting, Replica Selecting, Replica Consistency Management and Security Management. The replication technologies related with each aspect are analyzed and discussed in details within some successful data grid application systems. Finally, the future work on Data Replication is given.
