Puppet (software)

Puppet is an open-source automation tool used by IT professionals to manage and configure multiple computer systems consistently. It allows administrators to define system settings and tasks in code, called "manifests," which Puppet then applies across servers automatically. This ensures systems are set up correctly, remain consistent over time, and can be easily updated or repaired, reducing manual effort and errors. Puppet is especially useful in large-scale environments, enabling efficient, reliable, and repeatable management of infrastructure without needing to manually configure each machine.
