While automating your infrastructure, keeping SSL certificates updated is important and sometimes overlooked (since I do this one time per year, why automate?), and can lead to some bad scenarios.

Sometimes you don't need or want a dedicated server for configuration management with Chef, and this is completely possible, you can use a knife plugin called `knife-zero` to simulate a local server with chef local mode and work everything within a repository.
