Puppet software lets you manage the software configuration on all the hosts on your network. It simplifies repetitive operations and ensures state and configuration integrity among large number of machines.

Puppet comes in both Enterprise and Apache-licensed open source versions; we worked with the latter. Its powerful object-oriented configuration language supports inheritance and code reuse. Puppet can run on and manage a wide range of operating systems – Linux, FreeBSD, Solaris, and even Windows (partially) – so it's suitable for heterogeneous server environments running different distributions of Linux or even different operating systems.
