High-performance hybrid information service architecture

Abstract. We introduce a distributed high performance hybrid Information Service Architecture, which forms a metadata replica hosting system to manage both highlydynamic, small-scale and relatively-large, static metadata associated to Grid/Web Services. We present an empirical evaluation of the proposed architecture and investigate its practical usefulness. The results demonstrate that the proposed system achieves highperformance and fault-tolerance with negligible processing overheads. The results also indicate that efficient decentralized Information Service Architectures can be built by utilizing publish-subscribe based messaging schemes.
