Abstract

The Charron-Bost Database Replication Model was extended by adding consistency using Load Balancing technique. In addition, the Model was extended to achieve heterogeneous replication to bridge the gap among different database system. The framework for achieving heterogeneous replication between MySQL and Oracle database was also provided. The hybridization of Round Robin with Maximum Minimum RRMaxMin was simulated using Cloud Analyst and the performance was compared with other load balancing algorithm for response time and cost effectiveness. The findings of this study were that: The extended model enhance ability to perform heterogeneous replication in grid environment. The introduction of a new load balancing algorithm (RRMaxMin) brought about significant improvement in the cloud services. Out of all the algorithms that were evaluated, RRMaxMin performed better in terms of overall response time of 226.16ms and 89.9% cost effectiveness. The study concluded that load balancing strategy is a more reliable way to achieving heterogeneous replication in a distributed environment. The study recommended that RRMaxMin should be adopted in the cloud service to improve user satisfaction
