Terraform

Terraform is an open-source tool from HashiCorp for Infrastructure as Code (IaC). It lets you describe infrastructure, such as servers, networks, databases and cloud services, in declarative configuration files and provision it automatically.

Terraform compares the described target state with the actual current state and applies only the necessary changes. Through so-called providers, it supports numerous platforms and services, which makes infrastructure versionable, reproducible and manageable across platforms.
