Question

Publisher – Subscriber pattern where subsriber invoke a service.

Server as a Publisher, registered 10 agents as Subscriber.
I have successfully implemented this using Publisher-Subscriber pattern.
In my case, one of the agent invoke a service on the server and server notifies to all its registered agents.

Is there any simple way to include this service invocation by agent, in my existing Publisher-Subscriber pattern?

Answer 1

As you have no single publisher consider switching from publish-subscribe paradigm to event bus.

So your current server should expose API that allows two operations:

• Event handler registration
• Event publishing
