The increase in the use of web services has rendered its workload to be highly uncertain. The workload and the execution environment of web services affect their performance since they are non-uniform and unpredictable. Hence, estimation techniques are required to predict the performance of web services considering their dynamic workload. This paper presents a methodology to estimate the response time of web services over a given time horizon by providing a mathematical model. The deployment environment is analyzed by considering the configuration of the resources and the workload that fluctuates over a period of time. A case study on Travel care application is presented to illustrate the methodology. The tool SMTQA (Simulation of Multi-Tier Queuing Applications) is used to carry out sensitivity analysis on the configuration of resources so that the behavior of the resources can be analyzed. This analysis helps to improve the performance of web services by identifying the bottleneck resources. Moreover, it provides a possibility to determine the performance objectives.
