Design and implementation of cloud-based performance testing system for web services

Nowadays testing plays an important role in software development process. While software testing is expensive and time-consuming, sufficient testing is hard, especially for a distributed system using web services technique in the real circumstance. The development of cloud computing provides us new ideas to solve these testing problems. To address these issues, we propose a framework which integrates cloud computing and performance testing technologies. In this paper, first we present the architecture of the cloud-based performance testing system for web services (CPTS), which is a portable, extensible and easy-to-use framework for generating and submitting test workloads to computing clouds. Then, we show the process how to use CPTS to run a performance test and present the concept of dynamic migration in CPTS. Finally, we present our experiences with CPTS in Amazon EC2. We found that the CPTS allows a user to easily set up and test a web services system on the cloud and improve test effectively.
