Introducing ØMQ and pyzmq through examples

ØMQ is a messaging library that has the capability to revolutionize distributed software development.

Unlike full fledged messaging systems, it provides the right set of abstractions to incorporate various messaging patterns. It also provides the concept of devices which allows creation of complex network topology.

To get a quick overview, you can read the introduction to ØMQ by Nicholas Piël.

ØMQ sockets are a light abstraction on top of native sockets.
This allows it to remove certain constraints and add new ones that makes writing messaging infrastructure a breeze.
  • ØMQ sockets adhere to predefined messaging patterns and has to be defined during ØMQ socket creation time.
  • ØMQ sockets can connect  to many ØMQ sockets unlike the native sockets.
  • There is constraint on type of ØMQ sockets  that can connect to each other.

ØMQ has bindings for many languages including python (pyzmq) and that makes it very interesting.

It has been fun learning the basics and I hope soon to create some real world examples to whet my knowledge of ØMQ. Till then, I hope that the mini tutorial on ØMQ and pyzmq will serve as good introduction to it's capabilities.

Check out : http://readthedocs.org/docs/learning-0mq-with-pyzmq/en/latest/index.html

It is quite easy to get started. Use virtualenv and pip.
pip install pyzmq-static
pip install tornado

Checkout the code from https://github.com/ashishrv/pyzmqnotes
Follow some of the annotated examples to see the awesomeness of ØMQ.

Do post your feedback on the mini tutorial here as comments.
