Measuring Overhead for Distributed Web Service Handler Beytullah YILDIZ Department of Computer Engineering TOBB University Economics and Technology Ankara Turkey E mail byildiz etu edu tr Abstract Service Oriented Architecture perfectly manifests itself in Web services which create seamless and looselycoupled interactions Web service utilizes supportive functionalities such as security reliability and so on These functionalities are called as handlers which incrementally add new capabilities However adding new handlers into the execution path may cause performance and scalability problems Distribution of handlers solves these problems by providing abundant computing resources However pulling a handler out of its native place and positioning it away from Web service endpoint brings additional costs Hence we will investigate the overhead of handler distribution for various environments Keywords Web Service Distributed Computing Handler Structure Multi core I INTRODUCTION Web service is defined by World Wide Web Consortium W3C as a software system that provides a standard means of interoperating software applications running in variety of platforms 1 It utilizes Web Service Description Language WSDL to provide a standard way to define services 2 A Web service can be published to a Universal Description Discovery and Integration UDDI registry to be discovered and defined how to be interacted over Internet 3 In addition Web service framework uses Simple Object Access Protocol SOAP as de facto standard to exchange structured information 4 Requests and responses travel within SOAP messages Hence Web services strongly employ SOAP processing engines and transport helpers to contribute the interactions These functionalities are combined in middleware system called Web service container which essentially hides the complexity of SOAP processing and details of message transportation Web service employs additional functionalities which are called handlers by utilizing the
