Cloud Computing Simulation Using CloudSim Toolkits

Abstract

Cloud simulation aims to power the next generation data centers and enables application service providers to lease data center capabilities for deploying applications depending on user QoS (Quality of Service) requirements. Cloud Simulation applications have different composition, configuration, and deployment requirements. Quantifying the performance of resource allocation policies and application scheduling algorithms at finer details in Cloud computing environments for different application and service models under varying load, energy performance (power consumption, heat dissipation), and system size is a challenging problem to tackle. in this paper we propose CloudSimulation:an extensible simulation toolkit that enables modeling and simulation of various Cloud Simulation environments. The CloudSim toolkit supports modelling and creation of one or more virtual machines (VMs) on a simulated node of a Data Center, jobs, and their mapping to suitable VMs. It also allows simulation of multiple Data Centers to enable a study on federation and associated policies for migration of VMs for reliability and automatic scaling of applications between user and hosts due to cloudlet Keywords— Cloud Computing Simulation, Data Center,VM Scheduler, Host.
