In any organization, systems do not generally stay the same. Applications are updated and removed, configuration files are changed, new users are added and removed, and much more.
If you just have one server, then it won't provide much benefit, but think about updating a configuration file across 10 or 100 or even 1,000 servers.
Configuration management tools help us achieve these use cases in a much more simple manner.
There are many configuration tools such as Puppet, Chef, and Ansible that are used but as a personal choice, Ansible is by far one of the best tools I have used.
Did I tell you that Ansible has a faster learning curve as well for beginners? Well, now you know. We've actually had many interns who managed to write quite a decent playbook within just one week of knowing what Ansible is.
Due to its simplistic, efficient, and non-dependency...
