Subject Re: Kafka brokers on HTTP port

Yes, those are potential issues if you make your Kafka cluster publicly
accessible. There are some features currently being worked on that could
help address these problems (some security on connections and quotas), but
they are still in progress. You'll probably want a proxy layer to handle
this.

As for auto-scaling, you can do this but you should be aware that Kafka
doesn't currently do automatic balancing of data as brokers are added.
You'll need to manage that process yourself when new brokers are added.
