Terraform is a tool for provisioning and managing infrastructure, particularly useful for multi-cloud infrastructure deployments. Organizations adopting a cloud operating model use Terraform to provision infrastructure, but often miss out on the cost-saving benefits of the cloud. To address this, Terraform has features such as modules, Sentinel policies, and automated policy enforcement that organizations can use to optimize cost savings and management. By codifying infrastructure components into modules, codifying guardrails with Sentinel policies, limiting machine size and lifespan, and automating workflows, organizations can realize significant cost savings and reduce manual effort in managing their infrastructure.
