Hiera is a simple pluggable Hierarchical Database. It is used by puppet to be able to structure your infrastructure data. Using it, you can achieve code and data separation, so that string literals do not clutter your manifests, and hierarchical structurization of your profiles. This talk is a brief introduction to base concepts and examples of Hiera, with the main target of allowing you to decide whether hiera will be useful for you or not.
