"Having a developer setup and manage a development environment is a great learning experience. But it doesn't scale. Once you have a team, the time you take to setup an environment is precious time wasted. And it gets even more involved as your stack gets complicated."<p>Using Ansible (same idea as Chef and Puppet) I can go from zero to fully ready (setup exactly as I want it) in less than 20 minutes, and my system does all the work during that time. I can do this for as many servers as I need. Every step of the process is scripted, so it does the exact same routine every time. I can also regularly iterate my server scripts just like I iterate my dotfiles for all my other tools.<p>These are my tools. They put bread on the table. I like for my tools to be exactly how I want them and under my full control. Action.io will be interesting to check out though.
