Final answer:
The OCI Resource Manager is the service that utilizes Terraform to facilitate Infrastructure-as-code within Oracle Cloud Infrastructure. It helps in organizing resources, managing OCI resources with Terraform configurations, and offers collaborative features.
Step-by-step explanation:
The Oracle Cloud Infrastructure (OCI) service that leverages Terraform to enable Infrastructure-as-code (IaC) is the OCI Resource Manager. Terraform is an open-source tool that allows developers and infrastructure engineers to define, provision, and manage cloud and other service resources using declarative configuration files. OCI Resource Manager integrates directly with Terraform to make infrastructure management easier, more consistent, and more reliable.
By employing OCI Resource Manager, you can organize resources into stacks, which offer efficiency through modularity and reusability. It allows you to use Terraform configurations to create and manage OCI resources such as networks, compute instances, and storage. Additionally, OCI Resource Manager provides features for team collaboration, such as resource locking and detailed audit logs.
