A SEDA-based framework for building big web service

With the maturity of SO A and rapid development of Internet, more and more enterprises will open their resources to public using SOAP-based web service. Because SOAP protocol is based on XML-format data, parsing and generating SOAP message spends much time and consumes a vast of resources. Moreover, complex network environment poses challenge of extreme concurrent, dynamic contents, continuous high available, etc to build Internet services. Both problems mentioned above need to be considered in the design. Staged Event-Driven Architecture (SEDA) is intended to support massive concurrency requirements and make the construction of well-conditioned services simpler. This paper proposes a new type of framework to build SOAP-based web service utilizing the concept of SEDA and using configuration management to choose reasonable XML operation algorithm. At the same time, the architecture model of the framework is also described in detail. In SEDA model, a stage is basic unit. In the end, stages of the service framework are analyzed.
