Application Research Of Distributed Computing System On Based Of Web Services Technology

Along with the development of network, the applications of distributed system are more and more popular, and distributed computing technology is the key of Distributed System Implement. Now although various solutions of distributed computing can be choose, they have some big shortcoming: the interaction and interoperation between different software applications are not enough, and they are not fit for development of application in a loose-coupling environment like Internet. How to realize integration of various applications in wider network environment between enterprises than before have already become the biggest demand of creating distributed computing system. Web Services technology can easily overcome the limitations of traditional distributed computing solutions, integrate web services without seam and construct a new generation distributed computing system. At first, this paper introduces and analyzes the conception and theories about distributed computing technology and several popular solutions. With deeply analysis and comparison, how to use these technology and theories to design and develop new patterns of distributed computing system is also discussed. Then, a Web Services Management System is constructed, which is based on Axis technology from Apache Group to manage a web service to decrypt MD5 hash (implemented on Linux in HP Cluster System) and a web service to get MD5 hash (implemented on Windows in PC). The function modules of the whole system as web service are also deployed. Client can invoke these models or services with XML/SOAP. So the interaction and interoperation between different applications in distributed heterogeneous environment were realized. According to the design and implementation of the system, this paper discuss the solutions of distributed computing system with Web Services technology, and describe the environment construct and setting for developing web service, system's design, method and steps. At the same time, the advantage and the disadvantage of Web Services technology are testified and sum up.
