On-demand policy evaluation in HashiCorp Terraform Cloud allows users to evaluate the effects of policy changes before they are enforced, providing better visibility and control over infrastructure policy changes. This feature is designed to address challenges faced by compliance teams when introducing policy as code changes, such as syntax errors that can halt workspace runs. With on-demand policy evaluation, users can manually evaluate policies against a particular workspace without requiring a full plan or apply run, including workspaces not currently in scope of the policy set. This allows for more controlled and efficient management of policy changes, enabling users to measure the impact of new policies and compliance across their Terraform Cloud organization. The feature is now available in beta for use in HashiCorp Terraform Cloud, providing users with the tools they need to enforce policies across their infrastructure at scale.
