Quality of Service Evaluation of IaaS Modeler Allocation Strategies on Cloud Computing Simulator

Cloud computing is becoming popular among application developers nowadays. With the advent of cloud, application developers can use computing resources that are cost effective with almost zero hardware maintenance worries. Many Simulators for Cloud platform has been developed to better understand the behavior of this platform and one of the commonly used simulator is CloudSim. The Cloud simulator (CloudSim) is a tool that provides an environment for investigating and understanding the federation of cloud entities and events. The effect of variation in parameters such as number of host, host MIPS, host RAM (MB) size, host storage, host bandwidth and VM and cloudlet completion time in IaaS modeler has been studied in this work. The scheduling policy for allocating processing cores to virtual machines has also been studied. We introduce an approach using PCA and clustering technique that is expected to perform better compared to the existing FCFS method for the allocation strategy.
