Experimental Study to Improve Resource Utilization and Performance of Cloud Systems based on Grid Middleware

Cloud computing is a network of virtualized servers or virtual data centers that can deliver powerful applications, platforms, and infrastructures as services over the Internet. Virtualization technology based Cloud Computing has the advantages of system scalability. It, however, needs mechanisms to improve its resource utilization and to complement its resource management. So, we propose three methods to surpass the above limitations. We also conduct a variety of experiments with the proposed methods and show the improvement of overall system throughput and resource utilization based on the experimental results.
