When it comes to developing large systems with many interdependent parts, it’s common nowadays to use “queues.”

Runs as a daemon to link separate apps via a queue. Article includes suggested links.

Cet article explique ce qu'est AMQP et comment l'utiliser en Ruby.

The flexibility of the message and the exchange model is what makes AMQP such a powerful tool. Whenever a publisher generates a message, he can mark it as 'persistent' which will guarantee delivery through the broker - if there is an attached queue, it will accumulate messages until the consumer requests them. However, if you're streaming transient data (access logs, for example), you can also disable message persistence and not worry about overwhelming your broker. That's how you achieve 'exactly-once' vs 'at least once' semantics.
