This diagram shows a Dev and QA system using a two UDDI registries: one for publish and one for discovery. Those registries use the same key as the production UDDI registry, which is used by the Stage and Production systems for both publish and discovery. The Dev system uses auto-publish and auto-sync against the registry to keep resources synchronized. The QA system uses manual sync against the Dev Discovery Registry to keep discovered resources synchronized. The Stage system uses manual sync against the Production registry. The Production system uses auto-publish and auto-sync against the Production registry.
