Is it possible to load balance MQTT broker? Can I use ELB to load balance MQTT? Any pointers in this direction would be helpful. I hit upon http://www.slideshare.net/kellogh/mqt
I prefer HAProxy to AWS ELB, because you can get more flexibility on IaaS or PaaS.

You can see haproxy-mqtt using Docker. The core haproxy.cfg file is here.
