Distributed resources such as hardware and software can be integrated to create a computing environment which allows multiple computer systems to share these resources. Grid computing provides this infrastructure. Terabytes of data are shared across grid environment and users accessing this data are increasing by the day. In the process of transferring these large amounts of data, the network faces congestion and latency, which consumes large amount of bandwidth. Hence data replication is implemented across grid computing environment as the remedy to this issue. Replication occurs by placing original copies of databases in various storage elements of a grid system. The copies of data (called “replicas”) synchronize with other replicas in order to ensure that they store the latest updates and therefore preserving data integrity. Replication provides better reliability, accessibility and load balancing among the storage elements of a grid environment.
Among the areas of interest are:
- Dynamic replication algorithms,
- Intelligent creation, deletion and movement of replicas,
- Synchronous and asynchronous protocols to update replicas,
- Topologies for replica distribution,
- Cost-estimation modeling for replica access,
- Combining replication with caching to improve performance.
