Puppet
Runner-up: OpenQRM
In another repeat performance from last year, Puppet takes top spot for
configuration management. If you administer greater than zero servers,
you will benefit from using a tool like Puppet. If you're managing fewer
than zero servers, well, we're not sure what that means. You probably
need Puppet to manage your counting skills. Whatever your reason,
configuration management is a hot topic, and Puppet is the hottest.
