Architecture Design of Distributed Computing System Based on SOA Model

With the sharp increase of data amount in modern computing process, it needs more powerful general computing ability to process and compute data. Web Services-based Distributed Universal Computing Platform (WSDCP) provides an inexpensive solution for large-scale computing tasks in a loosely coupled manner with high flexibility and node autonomy. System adopts Web Services, XML as technical support, through installation of intelligent probe on nodes to real-time collect the situation of node, and the disequilibrium task allocation and dynamical task regulation can improve system reliability. WSDCP system takes green computing concept as guiding concept, and takes advantage of idle CPU resources on the Internet, Which have positive significant for establishing resource-conserving society.
