0 likes•158 views
Do you have multiple configuration management languages in production simultaneously? Do you find yourself having to accommodate for multiple deployment flows, dependencies, code structures and syntax for tools that do similar tasks? This talk will consist of demos, stories and structures to help you quantify and define what is slowing your flow, recognize equivalencies between languages for translation, and help you map the way to successfully iterate towards unity of tooling with Puppet. In this session, I will: *Discuss causes and prevention of duplicate tooling *Quantify resource cost of duplicate tooling *Define existing language roles *Identify similarities in language structure *Discuss and demonstrate conversion techniques
