Chapter 1. Pulling RabbitMQ out of the hat

We live in a world where real-time information is constantly available, and the applications we write need easy ways to be routed to multiple receivers reliably and quickly. More important, we need ways to change who gets the information our apps create without constantly rewriting them. Too often, our application’s information becomes siloed, inaccessible by new programs that need it without rewriting (and probably breaking) the original producers. You might be saying to yourself, “Sure, but how can message queuing or RabbitMQ help me fix that?” Let’s start by asking whether the following scenario sounds familiar.
