Management and Placement of Replicas in a Hierarchical Data Grid
Grid computing is an emerging technology that presents new challenges. The management aspect of large scale, heterogeneity and dynamicity of the sites are the most important. In large-scale systems such as data grids, data access, pose problems of performance and quality of service. The use of replication techniques given can implement solutions with more or less effective in some of these problems. For this, the authors proposed an approach of dynamic replication in a hierarchical data grid. This approach can create or delete the data according to their popularity.
