"Real-Time" Topology Updates for Boundary Systems

Increasingly, monitoring solutions are concerned with assuring the availability of Services. To achieve this goal they must have an accurate and current internal representation of the Service Topology. For monitoring solutions, and other boundary systems, that are not the authoritative source of Service Topology, TOSCA should provide a means for discovery and "real-time" updates of Service Topology.

Use Case: A service assurance product wishes to reason about Service Topology for the purpose of performing its function. To do so, it ought to be able to discover Service's Topology as well as remain informed of any changes related to the topology.
