Puppet

Puppet is an IT configuration management tool that is used to automate the management of IT infrastructure. It uses declarative language to describe the desired state of the infrastructure and then makes the necessary changes to bring the actual state in line with the desired state. This allows for consistent and repeatable configuration across multiple servers and devices.

Puppet is used to automate tasks such as installing software, managing service states, and managing users and permissions. It can be used to manage servers running various operating systems, including Windows, Linux, and macOS. Puppet can also be used in combination with other tools, such as Vagrant and Docker, to manage virtual machines and containers.

Puppet is widely used in IT operations and DevOps environments for automating infrastructure management and configuration tasks, which helps to reduce errors, improve security and compliance, and enable faster delivery of new applications and services.
