New simulation toolkit for comparison of scheduling algorithm on cloud computing New simulation toolkit for comparison of scheduling algorithm on cloud computing provides reliable, customized and guaranteed dynamic computing environments for end-users in such a way so that more and more people tend to adapt the cloud environment in their workplace. Cloud computing is becoming an increasingly popular enterprise model in which computing resources are made available on-demand to the user as required. The unique concept of cloud computing creates new opportunities to align Business and IT goals. Job scheduling is an essential requirement in cloud computingenvironment with the given constraints. Some intensive researches have been done in the area of job scheduling of cloud computing. The scheduling algorithms should order the jobs in a way where balance between improving the performance and quality of service and at the same time maintaining the efficiency and fairness among the jobs. This paper aims at studying various scheduling algorithms recently proposed in cloud computing.
