Sensitivity Analysis of Cloud under Transient Conditions

Satyanarayana.A, P. Suresh Varma, M.V.Rama Sundari and P Sarada Varma

Cloud computing is a new economic computing paradigm in which information and shared resources can be accessed from a Web browser by customers. Clouds consists of a collection virtualized resources which includes both computational software and hardware facilities that can be provided to the customers based on demand. This on demand model creates a flexible and cost effective means to access compute resources. In cloud computing it is customary to consider that the job arrivals are characterized by Poisson process. This is assumption holds good if the job arrivals are homogeneous and independent of time. In this paper, we develop and analyze a cloud computing model with the assumption that the job arrivals are characterized by homogeneous Poisson Process. It is further assumed that allocation of Resources (Virtual Machines (VMs)) for each job dependent on number of jobs in the buffer at that instant using dynamic allocation strategy. The transient behavior of the cloud also analyzed by deriving various measures like mean number of jobs in the buffer, throughput of the cloud, utilization of the cloud and mean delay in allocation of resources etc,. The sensitivity analysis of the cloud reveals that the homogeneous Poisson arrivals and dynamic resource allocation strategy can reduce burstness in buffer and improve quality of service

Keywords: Cloud Computing, Dynamic Resource Allocation, Performance Evaluation, Poisson Process, Sensitivity Analysis
