Abstract Web Services has emerged as a dominant paradigm for constructing and composing distributed business applications and enabling enterprise-wide interoperability. A critical factor to the overall utility of web services is a scalable, flexible and robust discover mechanism. This paper improves UDDI specification, thus it could guarantee usability of response and append grid-like monitoring information of web service hosting environment to response, but modification to standard UDDI specification does not affect the interoperability. We also present two distributed and scale-well approaches for fully autonomous registries and cooperative registries to overcome the disadvantage of traditional registries. In other words, we provide an unstructured peer-to-peer network for fully autonomous registries and a structured peer-to-peer network for cooperative registries. The two kinds of peer-to-peer network for registries support complex query without influence on interoperability, and they are a suitable candidates to extend traditional web service registries.
