The CSC Open Source Program launched today with the first production ready version of Hanlon, a node provisioning solution. It is a major rewrite of the Razor project, which was originally written by Tom McSweeney and Nick Weaver two years ago, with an improved architecture and design. For people not familiar with Razor, Razor is an automated, policy driven OS provisioning and node control solution for both bare metal and virtual machines provisioning. A detailed overview can be found in Nick's blog . Tom McSweeney and Nick Weaver , who originally built Razor during their EMC days, launched it as open source through Puppet Labs , which grabbed a lot of attention from the community. A detailed history of Razor and the events that lead to the birth of Hanlon can be found in Tom McSweeney's Hanlon announcement blog . Coming back to Hanlon, Hanlon is released as two open source projects : Hanlon (the web server component to manage Hanlon nodes) and the Hanlon-Microke...
