Are there any good alternatives to RabbitMQ for low-end setups?

I've been using RabbitMQ in a few setups now, and I can't shake the feeling that there must be something that's more easily set up. Despite it's conveniences it's hard to justify MQ for a solution that only processes a couple of thousand messages a day, simply because maintaining RabbitMQ is so much work.

Does anyone know an AMQP implementation with a simple installation and maintenance process?

For those who don'开发者_开发问答t know it, RabbitMQ is an AMQP implementation written in Erlang. It is supposed to be very stable, but that is only really the case if you know enough about Erlang to avoid its problems. Whether it's memory limits or changes in the hostname, there is always a need to get deeper into it.

http://www.zeromq.org/ might be what you are looking for. If you are on Windows you might use MSMQ

EDIT: I guess I missed the AMQP part of the question.

ActiveMQ seems to be good alternative, I was using RabbitMQ to set up "cluster" over WAN, which is not supported by RabbitMQ cluster, since it requires all machines within same location.

It seems ActiveMQ is better than RabbitMQ, in the sense that it is easy to set up and maintenance, for "cluster"

Apache Qpid is another open source AMQP broker: http://qpid.apache.org/

Disclaimer: I haven't used it myself so I can't tell you how it compares to RabbitMQ.
