The job scheduling is to allocate certain jobs to particular resources in a particular amount of time. The job scheduling is to achieve a high performance computing and the best system throughput. In cloud computing there are many jobs requires to be executed by the available resources to achieve best performance ,minimal total time for completion ,shortest response time, utilization of resource usage etc. Because of these different objectives and high performance of computing environment we need to design, develop, propose a scheduling algorithm to outperform appropriate allocation map of jobs due to different factors. This paper is showing results on the basis of number of parameters for organizing the number of different jobs, to identify job completion times on current resource provision. And to adopt a dynamic algorithm for VM scaling. To evaluate results CLOUDSIM is simulator is used.
