Configuration management

Configuration management (CM) manages changes in the system or, to be more specific, the server runtime environment. There are many tools available in the market with which we can achieve configuration management. The popular tools are Chef, Puppet, Ansible, Salt, and so on.

Let's consider an example where we need to manage multiple servers with the same kind of configuration.

For example, we need to install Tomcat on each server. What if we need to change the port on all servers, update some packages, or provide rights to some users? Any kind of modification in this scenario is a manual and, if so, error-prone process. As the same configuration is being used for all the servers, automation can be useful here.
