PTCWA: Performance Testing ofCloud Based Web Applications M. S. Geetha Devasena, R. Kingsy Grace, S. Manju, and V. Krishna Kumar 1 Introduction Performance testing is the process of determining the stability of software and responsiveness under some work load. This paper deals with the performance testing of web applications in terms of resource utilization. The process of testing web application has to be done in prior to its release. This assures that the application does not suffer from being “slash-dotted” under a heavy user load [1]. Performance testing of web application analyses the working of application, web servers and databases under moderate and heavy user load. Since the web and internet have very dynamic performance capabilities and bottlenecks, performance testing of the web applications is important. 1.1 Pitfalls in Performance Testing of Web Applications Performance testing of web applications has some drawbacks. First and foremost, expecting performance tuning information as a result of the performance testing is not possible because it is designed only to provide response statistics [1]. The other drawback is the early occurrence of performance testing in the life cycle of the M. S. Geetha Devasena · R. Kingsy Grace () · V.
