Why puppet? Why now?
David Mytton's presentation at Puppet Camp London 2015 outlines the benefits of using Puppet for configuration management, emphasizing the importance of infrastructure as code for consistency, version control, and audit capabilities. It addresses common objections to Puppet adoption, such as perceived complexity and initial investment, while presenting various use cases including package deployment and cloud management. The document also highlights key Puppet features like PuppetDB, Hiera, and Facter for infrastructure management and analytics.
