Puppet is an open-source configuration management tool used to automate system administration tasks such as system configuration, deployment, and management. It’s designed to make the process of managing multiple systems easier and more efficient.
For example, Puppet can be used to ensure that all of your servers are running the same version of software, have the same configuration settings, and are up-to-date with the latest security patches. It can also be used to deploy new software packages or configuration changes across multiple systems at once.
