If DevOps is about automation and smoothing the relation between different teams responsible for developing the same application, configuration management is one of its pillars. Wikipedia defines CM as a systems engineering process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. Last week, I've been talking with someone who asked me some questions about CM and I was not able to introduce him to this topic, because I was diving deep into the complex use cases. I decided to write this post.

As you may understand, in this post, we are going to use a very basic example, a simple use case, probably not the use case you will find in large teams and corporations but consider it as an introductory example.
