[rabbitmq-discuss] RabbitMQ -- communicate between 3 different machines?

[Alvaro Videla]

Hi Shalom,

You can read the guide here: http://www.rabbitmq.com/pacemaker.html

Not that I like to do self advertisement, but you can also read our book about RabbitMQ that discusses clustering too: http://bitly.com/rabbitmq

Cheers,

Alvaro
