What is the significance of the name Puppet?

Well, who knows? 

But all we know is that it surely does a lot more than just be a puppet.

Puppet consists of a custom declarative language to describe system configuration, which can be either applied directly to the system or compiled into a catalog and distributed to the target system via the client-server paradigm, and the agent uses system-specific providers to enforce the resource specified in the manifests. The resource abstraction layer enables administrators to describe the configuration in high-level terms, such as users, services, and packages, without the need to specify OS-specific commands.

And the result of the same is huge! It ends up helping in deploying, managing, and configuring your servers and mostly, contributing to your DevOps culture. Isn’t that amazing? 

Being the favorite tool of so many organizations, it is quite obvious that Puppet will throw a hell lot of interview questions your way.
