What is Puppet? Puppet is written in Ruby language and was developed by Puppet Labs, founded by Luke Kanies in 2005. Currently Puppet is supported by Puppet Labs and it is licensed under GPLv2 until version 2.7.0 and Apache 2.0 license after that. Puppet is involved in scripting of deployment of production system. Puppet is used to control an entire server starting from installation, configuration, managing, and maintaining server. Puppet can manage thousands of hosts. Install Puppet agent on hosts and then define the hosts in Puppet master server. All other tasks like installation, configuration, and so on will be done by Puppet automatically. Puppet can be used for quick and fast deployment of business applications both on-premise and in the cloud as it can quickly scale from tens of servers to thousands.

Puppet Overview How does Puppet Works Puppet is a declarative language which means the result needed is to be configured inside of Puppet. Puppet will then define the desired infrastructure and simulate the configuration once before executing them. After enforcing the action it would then report any differences in the actual and desired state which can be then resolved. As system administrators acquire more and more systems to manage, automation of mundane tasks is increasingly important. Rather than develop in-house scripts, it is desirable to share a system that everyone can use, and invest in tools that can be used regardless of one’s employer. Certainly doing things manually doesn’t scale. Puppet has been developed to help the sysadmin community move to building and sharing mature tools that avoid the duplication of everyone solving the same problem. It does so in two ways: It provides a powerful framework to simplify the majority of the technical tasks that sysadmins need to perform -The sysadmin work is written as code in Puppet’s custom language which is shareable just like any other code. -This means that your work as a sysadmin can get done much faster, because you can have Puppet handle most or all of the details, and you can download code from other sysadmins to help you get done

even faster. The majority of Puppet implementations use at least one or two modules developed by someone else, and there are already hundreds of modules developed and shared by the community.
