how to deploy message queues like rocketMq or pulsar in environments where initiating connections are not allowed?

Question

I need to publish messages to clients who run in environment where initiating connections are not allowed, but accepting connections are ok.

with rocketmq or pulsar, the issue I run into is that they all require clients (or broker, or proxy) to initiate connection to register themselves.

wondering what's the correct way to deploy them in this situation? or any other similar software that is suitable for this scenario?

Answer 1

what do you means "initiating connections are not allowed?"
