Hi @ProsenjitDas,
The cloud platform provides the same Event Broker software as a service. There are some restrictions, but I don’t believe this is one of them. Can you check your Event Broker version in the cloud and let me know what it is?
Also when you go into the PubSub+ Broker Manager (top right of screen once you choose your messaging service) and click the Connectors menu option do you have anything available?
