Performance of Cloud-Based Scalability and Load with an Automation Testing Tool in Virtual World

The development in cloud computing provides limitless capacity which provides opportunity to evaluate an application performance based on its nature to scale. This paper aims at the analysis of Performance using the Google App Engine(cloud computing paradigm). Virtual Office application is chosen as example to perform experiment of testing the scalability in turn maintaining the performance. An Automation Testing Tool - Test Harness has been used to perform the scale testing of the application while being deployed on the cloud. Results have seen shown in the form of request type and response times(Average time taken/request). Taken into account the consideration that when the application load goes up the Google Cloud expands(increases instance hours) without affecting the running application.
