Cloudsim: simulator for cloud computing infrastructure and modeling

Cloud Computing aims to deliver reliable, secure, fault-tolerant, sustainable and scalable infrastructure for hosting Internet-based application services. To model and schedule the different applications and services for cloud infrastructure system is an tremendous challenging task which requires different load and energy performance. This problem is solved by introducing CloudSim: a simulation framework that provides simulation, power to manage services and modelling of cloud infrastructure. In this paper we have discussed about the working of CloudSim & about its updated versions. (C) 2012 Published by Elsevier Ltd.
