David Willson, trainer extraordinaire and all round good egg is doing a class on Puppet at DenHac this Saturday.
Puppet is a tool for Configuration Management, Software Deployment, and Provisioning. We use it at my work to deploy software and configurations to anywhere from tens to a thousand servers in any of our 3 Denver or 1 Tokyo datacenters in minutes.
Come learn about this wonderful tool and support David's open source group as well as DenHac who is providing their training room for this class.
The class is free, but please, drop a donation in the DenHac donation box so that this wonder facility continues to be available for future training and events.
