Why are facts gathered in puppet and ansible

Question

There are facts gathered while using Ansible and Puppet(I have used only these two tools). I don't understand the point of gathering these facts. Where are these going to be used?

Answer 1

The facts gathered by these tools are actually very useful and used in many situations. For example,

• You can create a web server configuration template and automatically fill in the appropriate IP address for a particular virtual host
• You can also determine a lot about your system like that your server's distribution is ubuntu so you should run apache2 instead of httpd
