UDDI (Universal Description, Discovery, and Integration) is a directory to register and locate web service application. It facilitates businesses to easily and dynamically find and transact with one another through their preferred services. The present centralized UDDI structure is less robust and it is difficult to support a large number of Web services. It has become the bottleneck of the whole system and would cause single node failure problems. There is lack of interoperability between UDDI registries because different registries have different usage policies and pose various requirements on acceptable announcements and retrieval demands of Web services. These problems can be solved by distributing the functions and volume set of data of UDDI.
