Puppet is a configuration management tool which allows easy deployment and configuration ranging from 1 to 1 thousand servers (and even more). Even though its common knowledge for devops, puppet is still a strange piece of software for developers. How does it work and what can it do for you as a developer? This talk is about the "other" side of development: the actual deployment of your software. It's not hard to have a VPS up and running at some cloud hosting company but when it comes to management of systems, many things needs to be taken care of. This talk is not so much about how operations and development can work together in a "devops" methodology, but how configuration management tools like puppet, vagrant, veewee etc can make deployment AND development easier.
