Which OCI service leverages Terraform to configure infrastructure as code?

The correct service that leverages Terraform to configure infrastructure as code is Resource Manager. Resource Manager is designed to simplify the management of infrastructure by allowing users to define and provision resources in OCI using Terraform configurations. This service provides a way to automate the provisioning of cloud resources, ensuring that infrastructure can be managed consistently across environments.

By using Resource Manager, organizations can take advantage of Terraform's declarative language to define their infrastructure requirements. This integration supports best practices such as version control for infrastructure code, making it easier to track changes, collaborate among team members, and maintain an accurate depiction of the deployed resources.

The other options do not involve Terraform for infrastructure management. Compartment Trigger is related to event-driven architecture, Events facilitate managing event flows within OCI, and Oracle Function provides a serverless computing environment. However, none of these directly integrate with Terraform as a core functionality to configure infrastructure as code like Resource Manager does.
