ZeroMQ is the opposite of a queue

(written by lawrence krubner, however indented passages are often quotes). You can contact lawrence at:

Reading this again, several years after the first time I read it, and now it occurs to me: I would use ZeroMQ only in exactly those situations where I would not use a queue. If I only need a queue, I can use Kestrel. But if I need some messaging pattern that is not supported by any queue, then I would use ZeroMQ. That is, if I had a truly unique situation that needed a unique pattern, then ZeroMQ would be the perfect library to use to build out that pattern.
