Puppet is a server automation framework that performs administrative tasks across Linux, Unix, and Windows systems based on centralized specifications.
Puppet solves the problem of managing infrastructure at scale by allowing operators to declare desired system states rather than executing manual commands on individual machines. It works by reading a centralized specification and automatically applying administrative tasks such as adding users, installing packages, and updating server configurations across multiple systems.
Organizations should choose Puppet if they need to manage infrastructure across heterogeneous environments spanning multiple operating systems. It suits teams managing large numbers of servers where consistency and repeatability are critical. The project offers both an open-source version and Puppet Enterprise, which adds orchestration features, a web console, and professional support for organizations requiring those capabilities.
The project maintains semantic versioning and recommends users stay current with patch and minor releases as they become available. Bug fixes and ongoing development occur in minor releases for the current major version, while security fixes are backported to previous major versions on a best-effort basis until those versions are no longer maintained. Long-term support including security patches and bug fixes is available through commercial licensing. The project uses an HTTP API for integration and provides comprehensive documentation through a dedicated docs site. Community support is available through GitHub Issues, a mailing list, and a Slack channel.
