This document compares Terraform Open Source to Terraform Enterprise. Terraform Open Source has limitations in version control, sharing state easily, and lack of automation pipelines. Terraform Enterprise addresses these limitations with solutions like centralized workflows through version control and automation, controlling access to workspaces and secrets, and using Sentinel for policy enforcement and governance. The document then outlines key features of Terraform Enterprise like private module registry, remote runs, variables, audit logs, and SAML integration.
