Service Oriented Architecture perfectly manifests itself in Web services, which create seamless and loosely-coupled 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, the authors investigate the overhead of handler distribution for various environments.
