Simulation of cloud infrastructure using CloudSim simulator: A practical approach for researchers

Cloud Computing has evolved greatly in the recent years due to its characteristics of being secure, highly reliable, fault-tolerant, sustainable, and highly scalable; or we can say that it is capable of dynamically delivering IT resources over the Internet. Hence a lot of researchers and experts are working on improvising the cloud technology. To assess the performance of cloud environment, cloud simulators play an important role as it is a challenging task to perform experiments on the real cloud (which would incur huge cost in terms of currency if experiments are repeated). This paper gives a step by step practical approach towards simulating cloud components or cloud environment using the (open source) CloudSim simulator. It shows in-depth analysis and the factors responsible for simulating cloud concepts for your experiments or research or industry specific application.
