Abstract: Service Oriented Computing is a design paradigm that utilizes autonomous heterogeneous service applications as the fundamental elements to develop new composite functionalities at reduced cost and time. Web service is the standard way to implement the service oriented computing concepts in which business functions and resources are published, described, discovered, orchestrated and invoked using open standards and protocols. The web services emerged as an intelligent middleware web based technology for sharing business processes and resources amongst the disparate enterprises over the internet. Performance evaluation of service is an important criterion to be assessed by end users and service providers before adopting web services to deal with the challenging global markets. In this perspective, we propose to implement a composite ATM services using. Net technology to evaluate trustworthiness of web services in dealing with massive users. The uniqueness of our proposed system is the hierarchically designed parent and child services where the parent service authenticates a user to access resources and redirects the userís query for executing child service for adequate solutions. The industry standard testing software tool, Mercury LoadRunner was deployed to test our proposed e-ATM system and record the performance metrics to analyse the quality aspects of the service. The outcome of the experiment will help in adoption and usage of the web services in diverse business enterprises. We present here the architecture, framework of testing, transaction status and reliability estimation of web services under massive stress of service users.

 

Keywords: SOC, Web Services, SOA, SOAP, QoS, Reliability, ATM, e-ATM.
