摘要：Cloud computing refers to act of providing various resources to the job requests over internet. With the tremendous increase in Cloud services utilization, the allocation of resources to the job requests that enter the Cloud has become a challenging task that arrive in non-homogeneous fashion. In this paper we analyzed and performed sensitivity analysis of a Cloud computing model for allocation of resources to the jobs that enter into the cloud by using queuing models.We derived the sensitivities of various performance measures of the Cloud model under Non- Homogeneous conditions and made a comparative study of the sensitivities in the Cloud model between Homogeneous and Non-Homogeneous conditions by using various performance measures such as Mean number of job requests in the Cloud, Utilization, Throughput and Mean Delay of jobs in the cloud.It is observed that by using queuing theory, varying parameter values of jobs that arrive under non-homogeneous Poisson process has tremendous influence on performance measures as Mean number of job requests, Throughput, Utilization and Mean Delay of the jobs in the Cloud.
