Abstract: This paper explores the dynamic behaviour of the Running Cost when Web Application is hosted on the cloud using M/M/S/K queueing model through experimental study. As a part of earlier work the analytical model for Running Cost was proposed and numerically illustrated with respect to virtual machine operation cost and web request holding cost. There is a need to validate this model in real time scenario by conducting a experimental study to design the experimental setup and Test bed for conducting experiments on Amazon EC2 using Elastic Bean Stalk. The performance measures like end-to-end response time, utilization of computing resources consumed, blocking probability, average time spent in the system and average waiting time in the queue are considered to assess the dynamic nature of the cost model. Experimental results are compared with analytical results, it is observed that there is no significance difference between both the results.
