Infrastructure as Code in OCI using Resource Manager (Terraform)

Introduction Infrastructure management in cloud environments has evolved significantly with the adoption of automation and DevOps practices. Manual provisioning is error-prone and difficult to scale. In Oracle Cloud Infrastructure, Infrastructure as Code (IaC) is implemented using OCI Resource Manager, a managed Terraform-based service that enables automated, consistent, and repeatable deployments. This article provides a deep dive into OCI Resource Manager, including architecture, execution flow, state management, drift detection, hands-on examples, and real-world DevOps practices. What is Infrastructure as Code (IaC) Infrastructure as Code (IaC) is the practice of defining and managing infrastructure using code. Benefits Automation Consistency Version control Faster deployments What is OCI Resource Manager OCI Resource Manager is a managed service that uses Terraform to provision and manage cloud resources.
