ENTERPRISE MESSAGING USING A VIRTUAL MESSAGE BROKER

Abstract:

The present disclosure involves systems, software, and computer implemented methods for performing enterprise messaging with a virtual message broker. One example method includes operations to receive, at an enterprise messaging (EM) layer associated with a shared message bus, a request associated with a first client to subscribe to a second client, wherein the EM layer provides an abstraction to the shared message bus, and wherein the shared message bus is shared between the first client and the second client. A rule set associated with the first client is identified, where the rule set is defined in a service descriptor associated with an EM service interface bound to the first client. In response to determining that the requested subscription to the second client is allowed by the identified rule set, the subscription is created, and events corresponding to the subscription are provided to the first client for consumption.
