ZeroMQ (also known by OMQ or 0MQ or zmq), looks like an embedded networking library, but acts as a concurrency platform. It provides sockets that can carry atomic messages across multiple transports, including TCP, multicast, in-process, and inter-process. You can connect sockets N to N with patterns such as fan-out, pubsub, task distribution and request-reply. It is fast enough to be used as the fabric for clustered goods. Its asynchronous I/O allows you to build multicore applications that are scalable and can be used for asynchronous message processing tasks. It supports a number of language APIs and runs on all operating systems.
