title: Differences between ZeroMQ and WebSockets
body: <p>I'd like to know what the differences are between the ZeroMQ and WebSockets protocols. I know WebSockets was designed for web browser clients, but I'm assuming it can also be used server to server. And, in that case, I'm wondering if it would be good to use WebSockets instead of something else like ZeroMQ for real-time messaging. Specifically, I'm worried about reliability and missing messages in case of temporary network failure.</p>
