Web service technology is being increasingly used for commercial business applications. Reliability of the web services provided is an important criterion to enable the wide spread deployment of such services. This paper proposes analyzing the reliability of web services based on runtime fault information. Monitoring of web service interactions enable runtime faults to be detected and recorded. A sample application was developed and logs were designed for recording the service usage and faults information. Faults were injected in the sample application and faults during publishing, discovery, binding, execution and composition were recorded. Reliability estimation and prediction was carried out using Jelinski-Moranda Binomial model and Goel-Okumoto Non-Homogenous Poisson model.
