ReST or message broker or some other approach for integrating an on-premise and a cloud based spring boot application

I have 2 spring boot applications

The teller application has to work offline(if connectivity is down) as well. What is the best approach to broadcast events from the teller application to the cloud. I would not prefer to implement code to persist events.

What is the best approach? ReST/message broker or some other approach. If using a message broker, will the spring cloud stream abstraction queue events when the connection to the broker is down and retry.

I would go with the message broker (rabbit, kafka) and spring-cloud-stream, since your use case was exactly what/how it was designed. The microservcice (your app) is a consumer of the broker, that is: it can publish to and/or consume events from the broker. If the app is down the broker is up and potentially collecting events destined to the down app. Once app is up it consumes queued up events and so on. I'll stop here given the general nature of your question but feel free to follow up with more details.
