Puppet is an open-source configuration management tool that helps system administrators automate the configuration, deployment, and management of a server infrastructure. It is used to automate repetitive tasks, such as installing and configuring software, deploying applications, and managing system configurations.
For example, if you have a large web server infrastructure, you can use Puppet to automate the process of installing and configuring web servers, deploying applications, and managing system configurations. This can help reduce the time and effort required to manage a complex server infrastructure.
