Android Question Status update to 100 devices in 1 second

I need advice on which methods I could use to send out a status, in real time, to 100 devices or more.
So one app will update the status and the other 100 devices will "fetch" the status.
I expect each device will have to be logged into service and will have to keep checking it to see if the status has changed. At least that is what i think has to happen.
The status update needs to reflect within a second, on every device. Is this even possible?

Setup a MQTT broker and let all clients listen to it.
Publish a new MQTT Message to the broker.
It should receive fast on all devices if they are running and still listening.
Thanks Don, I'll check this out. I have never even heard of a MQTT broker.
