A Layered Architecture of Service Organization in AegisGrid

Abstract. In AegisGrid, a special Architecture of Service Organization is required to organize large-scale services. According to the characteristics of AegisGrid, this paper provides a layered architecture of service organization, AG-SOA, solving the key problems in large-scale services ’ architecture. It also describes the method of classification of services. Methods and critical algorithm are provided for service registry and service discovery. Experiment shows that AG-SOA is an architecture that fits the characteristics of large-scale services organizing and the dynamic properties of the services in AegisGrid, and costs less in service registry and service discovery.
