MQTT broker for Google App Engine

0 votes
I've successfully got my GAE up and running using Java. Now, I wanted to run a MQTT broker on my GAE web framework and cloud using a backend. But I just couldn't find anything on the internet that could even point me in the right direction. Now, I'm left wondering if it's even possible to do it or not?
Please help!

You had a hard time finding anything at all because the GAE backends have been replaced! You, now, need to have automatic scaled instances as frontend and manual scaled instances as backend. Plus, the MQTT is a protocol acting on top of the TCP/IP, which means that running a MQTT server will require the opening of a listening socket. And, sadly, those are not supported on your normal App Engine instances yet. So, a managed VM or running a full JVM is your best chance at running the MQTT broker. A full JVM that allows listening sockets or Managed VMs that provide access to most benefits and services of GAE.
