Infrastructure as Code

"Infrastructure as Code (IaC) is the process of managing and provisioning computing infrastructure and their configuration through machine-processable definition files, rather than physical hardware configuration or the use of interactive configuration tools. The definition files may be in a version control system. This has been achieved previously through either scripts or declarative definitions, rather than manual processes, but developments as specifically titled 'IaC' are now focused on the declarative approaches." - wikipedia
