A Lightweight Inter-node Operation for UDDI Cloud

Coordinated UDDI public registries disappeared almost two years ago. In 2006 the UDDI cloud, a registries federation managed by IBM, HP, Microsoft and SAP, was shut down with the end of the UDDI business registry (UBR) project. UDDI is still widely adopted for private registries. Isolated public registries are quite rare and an UDDI coordination mechanism is still missing. In URB a pure entries replication mechanism was allowing access to all the entries published on each server. However, such pure replication does not scale and prevents the creation of dynamic federation of UDDI registries. This paper describes a work-in-progress solution based on a inter-node operation enabling the replication APIs to distribute the entries across a distributed hash table (DHT). Thus, it reduces the number of replicated entries to a sub-set of nodes participating in the UDDI cloud and opens a new possible scenario for the adoption of the UDDI standard.
