==Types of approaches ==

There are generally two approaches to IaC: [[declarative programming|declarative]] (functional) vs. [[imperative programming|imperative]] (procedural). The difference between the declarative and the imperative approach is essentially '' <nowiki/>'what' '' versus '' <nowiki/>'how' ''. {{anchor|Declarative}}The declarative approach focuses on what the eventual target configuration should be; the {{anchor|Imperative}}imperative focuses on how the [[infrastructure]] is to be changed to meet this.<ref >{{cite web

}}</ref> Other vendors rely on adjacent communities and leverage other IaC frameworks such as [[PowerShell]] DSC.<ref name=powershell/> New vendors are emerging that are not content-driven, but model-driven with the intelligence in the product to deliver content. These visual, object-oriented systems work well for developers, but they are especially useful to production-oriented DevOps and operations constituents that value models versus scripting for content. As the field continues to develop and change, the community-based content will become ever more important to how IaC tools are used, unless they are model-driven and object-oriented.
