<p>Yes. NATS is a publish and subscribe system that also has distributed queueing functionality on a per subscriber basis. When you publish a message, for instance at the beginning of a request, every subscriber will receive the message. If subscribers form a queue group, only one subscriber will be picked at random to receive the message. However, note that the requestor does not know or control this information. What the requestor does control is that it only wants one answer to the request, and NATS handles this very well by actively pruning the interest graph.</p>

<p>NATS can be deployed to have an HTTP(s) monitoring port - see the demo server here: <a href="https://demo.nats.io:8222/" target="_blank">http://demo.nats.io:8222/</a>. Alternately, there are several options available, including some from the active NATS community:</p>
