Terraform
Terraform allows infrastructure to be expressed as code in a simple, human readable language called HCL (HashiCorp Configuration Language). It reads configuration files and provides an execution plan of changes, which can be reviewed for safety and then applied and provisioned.
Extensible providers allow Terraform to manage a broad range of resources, including IaaS, PaaS, SaaS, and hardware services. Terraform is widely used in modern platform engineering to deploy acorss cloud providers like AWS, Azure, Google Cloud, and others.
