One important difference with the HTTP load balancers we have seen in the previous chapter, is that, here, the consumers have a more active role. In fact, as we will see later, most of the time it's not the producer that connects to the consumers, but they are the consumers themselves that connect to the task producer or the task queue in order to receive new jobs. This is a great advantage in a scalable system as it allows us to seamlessly increase the number of workers without modifying the producer or adopting a service registry.
