I think you can combine AWS Lambda with other PUB/SUB service like PUBNUB https://www.pubnub.com/docs/pubnub-rest-api-documentation.

1. front-end/app use AWS Lambda to dynamically create and manage topics
2. front-end/app get topic info from AWS Lambda or DB
3. front-end/app join corresponding topics and send message to PUBNUB directly
