Infrastructure as code
12 likes•4,117 views
The document discusses infrastructure as code and related concepts. It introduces just enough operating systems using Vagrant and VeeWee to package applications. Just enough image building is covered using VeeWee to create minimal OS images from source configurations. Just enough infrastructure code is explained through configuration management tools like Chef Solo, Chef Server, and Crowbar that allow infrastructure to be coded and version controlled. The presentation aims to provide feedback to further the discussion on DevOps approaches.
