READY is an event notification service that provides efficient, decoupled, and asynchronous event notifications. READY supports consumer specifications that match over single and compound event patterns, communication sessions that manage quality of service for event delivery, grouping constructs for sessions and specifications, event zones and boundary routers that bound the scope of event distribution and control the mapping of events across zones.
