ZeroMQ
15 likes3,765 views
ØMQ (ZeroMQ) provides a simple way to connect different codes across various transports like in-process, inter-process, TCP, and multicast. It uses a socket interface that supports common messaging patterns like request-reply, publish-subscribe, and task distribution. These sockets can be connected in a flexible topology to build scalable, concurrent applications that take advantage of multicore systems. ØMQ has language bindings for many languages and runs on most operating systems.

- 2. A ØMQ socket is what you get when you take a normal TCP socket, inject it with a mix of radioactive isotopes stolen from a secret Soviet atomic research project, bombard it with 1950-era cosmic rays, and put it into the hands of a drug-addled comic book author with a badly-disguised fetish for bulging muscles clad in spandex. Yes, ØMQ sockets are the world-saving superheros of the networking world.

- 16. in a Hundred Words ØMQ (ZeroMQ, 0MQ, zmq) looks like an embeddable networking library but acts like a concurrency framework. It gives you sockets that carry whole messages across various transports like in-process, inter-process, TCP, and multicast. You can connect sockets N-to-N with patterns like fanout, pub-sub, task distribution, and request-reply. It's fast enough to be the fabric for clustered products. Its asynchronous I/O model gives you scalable multicore applications, built as asynchronous message-processing tasks. It has a score of language APIs and runs on most operating systems. ØMQ is from iMatix and is LGPL open source.
