How to: Server Configuration Management
-	There is a [large set](https://en.wikipedia.org/wiki/Comparison_of_open-source_configuration_management_software) of open source tools for managing configuration of server instances.
-	These are generally not dependent on any particular cloud infrastructure, and work with any variety of Linux (or in many cases, a variety of operating systems).
-	Leading configuration management tools are [Puppet](https://github.com/puppetlabs/puppet), [Chef](https://github.com/chef/chef), [Ansible](https://github.com/ansible/ansible), and [Saltstack](https://github.com/saltstack/salt). These aren’t the focus of this guide, but we may mention them as they relate to AWS.
