Definition: Service Registry ABB is a Data Object that enables the implementation of a central repository of information that contains metadata about the available digital services.

All of these kinds of services are used in some form or another by distributed applications. Each time they are implemented there is a lot of work that goes into fixing the bugs and race conditions that are inevitable. Because of the difficulty of implementing these kinds of services, applications initially usually skimp on them, which make them brittle in the presence of change and difficult to manage. Even when done correctly, different implementations of these services lead to management complexity when the applications are deployed. https://zookeeper.apache.org/ Interoperability Saliency: The Service Registry ABB is a key interoperability enabler because it provides access to software systems over the Internet using standard protocols. In the most basic scenario there is a Web Service Provider that publishes a service and a Web Service Consumer that uses this service.
