WAMLB: Weighted Active Monitoring Load Balancing in Cloud Computing

Nowadays, cloud computing is an amazing and fast-growing area in research industry. It provides IT-related service through Internet. Load balancing is an essential feature in cloud computing environments, and without proper load balancing, we cannot expect better response time. In traditional active monitoring load balancing techniques in which they generally check least loaded virtual machine and those who are least loaded selected for execution of task, some authors are also select the virtual machine randomly. In our proposed strategy for assigning the virtual machine, we calculate weight factor on the basis of physical memory, bandwidth, number of processor, and processor speed. After calculating the weight of each virtual machine, we select those virtual machine that is highest weight and available for execution of the task. We also verified our results with existing work through CloudAnalyst that is CloudSim-based simulator; our result shows the improvement over existing one.
