Configuration Management started in the late 1960s in the US Military. They specified exactly how mainframe systems needed to be setup.
In the last few years Configuration Management has become more popular in enterprises. A certain configuration for a system (e.g. database server) is defined. This describes a list of software, libraries or behavior this system should have installed. A central software tool processes this configuration.
If you add another server you can apply the same configuration to it too. The management tool will then proceed to setup the new node according to your configuration.
"The result: a perfectly configured system"
Recipe: Is a single configuration (e.g. create database "my_db")
Cookbook: A full set of configurations (e.g. setup database server)
Roles: Is a way to define certain patterns and processes that exist across nodes
Environments: Is a way to map an organization’s real-life workflow to what can be configured and managed when using Chef server (e.g Test/Staging/Production)
