Not to continue the debate but I am using messaging to perform tasks much like that definition ;). For example, when a worker picks up a task it will execute the code on the machine the worker is running on which may end up invoking the procedure call remotely if the worker is running on a remote machine. I think the biggest difference between RPC and messaging is what Justin outlined above: But to me, the RPC aspect is that it presents a predefined interface. A > function with a signature. This signature is validated as part of the RPC > implementation before it goes onto the wire. With messaging, no validation happens in regards to the message contents. The message is sent off to the broker and if there is a worker/consumer present that can deal with that message it does so. If there is not a consumer present that knows how to deal with the message then nothing happens unless either a timeout occurs or a consumer comes online that can deal with it. With RPC you have an explicit contract and at the time of invoking the RPC call, the call signature will be validated either client side or server side. If a contract was never created for the call signature an exception will be raised right then. This is that what I consider the major differences between RPC and messaging are...
