Some aspects of QoS for interoperability of multi service multi functional service oriented computing

Quality of service is the key indicator for service oriented architectures, because it directly expresses the operability and computational nature of the system. As such, we propose a quality evaluation framework for multi service multi functional hierarchical SOAP based web service. The overall interoperable quality is evaluated through load testing using Mercury Load Runner with Apache Tomcat web server and MySQL database engine. The recorded quality metrics are analyzed statistically. We present here in detail the architecture, observed metrics and analyzed results of the service oriented computing to validate the acceptability of the evaluation framework.
