[rabbitmq-discuss] RabbitMQ with WAN latencies

Tue May 17 12:39:45 BST 2011

Hi there,

I was wondering if you could help me determining if RabbitMQ is appropriate for some WAN scenario...

I have to send control messages to 50 or 60 machines deployed around the world, so they can subscribe to some message types and then perform some actions. Maybe some machines will be grouped in small clusters of 4-5 machines, and some tasks can be run by any machine in that group, but there will also be some tasks that will be targeted to some specific machines. There should be a very low traffic, with maybe just a couple of messages per second, so I was planning to use a simple architecture, with one central broker.

I want to keep things simple, but I'm a bit concerned about the effects latency could have, and I have also read that connectivity losses could have some negative impact. My question is, could I keep this simple architecture or will I need something a bit more complicated like rabbitmq with xmpp or shovel? I have not found many docs about using RabbitMQ on WANs, so maybe nobody is crazy enough for trying this... maybe I should not use RabbitMQ at all?  :)

Cheers
