Puppet

Puppet is IT automation software that helps system administrators manage infrastructure throughout its lifecycle, from provisioning and configuration to orchestration and reporting. Using Puppet, you can easily automate repetitive tasks, quickly deploy critical applications, and proactively manage change, scaling from 10s of servers to 1000s, on-premise or in the cloud.

Puppet uses a declarative, model-based approach to IT automation.

• Define the desired state of the infrastructure’s configuration using Puppet’s declarative configuration language.
• Simulate configuration changes before enforcing them.
• Enforce the deployed desired state automatically, correcting any configuration drift.
• Report on the differences between actual and desired states and any changes made enforcing the desired state.
