Open source Puppet vs Puppet Enterprise (PE)
Puppet Enterprise (PE) is the commercial version of Puppet and is built on top of the open source Puppet platform. Both products allow you to manage the configuration of thousands of nodes. Open source Puppet does this with desired state management. PE provides an imperative, as well as declarative, approach to infrastructure automation.
If you have a complex or large infrastructure that is used and managed by multiple teams, PE is a more suitable option, as it provides a graphical user interface, point-and-click code deployment strategies, continuous testing and integration, and the ability to predict the impact of code changes before deployment.
