Due to the increased loading the large number of users connected to pervasive web services during the past decade, their load testing and providing the needed resources in low timeand cost, requires more attention. In this context cloud computing technology offers new ideas to solve such problemsand has reduced the concern of large and complex testing systems. In this research in order to improve the quality and performance of web applications load testing, we proposed amethod for web applications load testing based on cloud computing. The proposed method uses the existing facilities inthe cloud including pool of computing resources without initial cost, unlimited data storage and cloud computing managerialprocedures, containing the actual load generating and multi-user concurrency testing, that lead to improved load testing flexibility,time and operational costs. Moreover, in this load testing method, in order to manage resources and virtual machines, significantimprovement is achieved by use of appropriate allocation,reducing performance and unnecessary migration avoiding methods. Through evaluation section of the proposed methodthrough a simulated test environment, it is shown that cloudbased load testing in comparison with traditional methods of load testing, improves factors such as effort, cost and time.
