ØMQ Sockets in Perl

Speaker: Anthony Johnson <aj@ohess.org>

Part message queue, part socket implementation sugar, ØMQ can be used to simplify socket communication and to scale out applications, and you don't even have to worry about the awful parts of socket communication. But more aptly and straight from the horse's mouth:

ØMQ (also seen as ZeroMQ, 0MQ, zmq) looks like an embeddable networking library but acts like a concurrency framework. It gives you sockets that carry atomic 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 LGPLv3 open source.

Find out what ØMQ is, where to use it, and learn about common patterns, pitfalls, and how it can be used for building anti-RESTful APIs. Anthony will elaborate on what it took to build a scaled out application and API using Python, Perl, and ØMQ.
