While gaffer (https://gaffer.readthedocs.org/) started as a set of Python modules and tools to easily maintain and interact with your processes, it is slowly becoming a solution to deploy, supervise and monitor processes and applications in a decentralized fashion without SPOF (Single Point Of Failure). Gaffer is already used in production behind some services.

The talk will present how to build such tool in Python using pyuv, tornado and other python libraries. How to make it scalable due to a simple design and what we did to make it compatible with Python 2 and Python 3.x .
