What are zeromq use cases?

Could you give so开发者_Python百科me examples of zeromq?

Let's say you want to have a bulletin board of some kind. You want to allow only some people to see it, by subscribing to the bulleting board.

This can be done using the publisher/subscriber model of ZeroMQ.

Now, let's say you need to send some asynchronous messages. That is, when a message is sent from system A and needs to get to system B, it is guaranteed to be delivered later, even if systems A and B cannot communicate at the moment when that message is sent. You can imagine a use case being SMS messages.

This can be done using asynchronous messaging model of ZeroMQ.

Basically, any JMS compliant solution like ZeroMQ will allow you to reliably broadcast or send a "message", whatever that message may be, to some other party with as little hassle as possible.

Please see the ZeroMQ blog -- they regularly post usage stories about different deployments, language bindings, etc.

IPython uses ZeroMQ for parallel computing features, the qt console and the notebook.

My personal use of this library is cross language communication:

I pass data between Python and Haskell

They also have an excellent guide that offers a complete peek into the possible use cases and their real time applications.
