The Discovery cluster provides a medium for Federation members to coordinate on development, deployment, and creation of interoperable specifications for Discovery services such as OpenSearch, DataCasting, and ServiceCasting. As such, a common Testbed to deploy services and/or clients would enable the Federation members to test the interoperability of Discovery services and clients. Moreover, having a common Testbed where Federation members from various data centers can access would provide a common platform that can be used to advertise their services.
