Configuration Management and Tools in DevOps

Chef & Puppet:

Chef is a tool used for Configuration Management and is closely competing with Puppet. In this blog, I will explain What is Chef, configuration Management and how Chef achieves Configuration Management with a use-case.

What is Chef ?

Chef is an automation tool that provides a way to define infrastructure as code. Infrastructure as code (IAC) simply means that managing infrastructure by writing code (Automating infrastructure) rather than using manual processes.

Below are the types of automation done by Chef, irrespective of the size of infrastructure :
  • Infrastructure configuration
  • Application deployment
  • Configurations are managed across your network

Architecture of Chef & Puppet :

Like Puppet which has a Master-slave architecture even Chef has a Client-Server architecture.

Chef is one of the most famous Configuration Management tools and is closely competing with Puppet.



Configuration Management :

Configuration Management helps in performing the below tasks in a very structured and easy way:
  • Figuring out which component to change when requirements change.
  • Redoing an implementation because the requirements have changed since the last implementation.
  • Reverting to a previous version of the component if you have replaced with a new but flawed version.
  • Replacing the wrong component because you couldn't accurately determine which component was supposed to be replaced.
Ways to manage your configuration :

There are broadly two way to manage your configuration namely Push and Pull configurations.
  • Pull Configuration : In this type of configuration Management, the nodes poll a centralized server periodically for updates.
  • Puss Configuration : In this type of Configuration Management, the centralized Server pushes the configurations to the nodes.
