| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Resource dependencies | Create a disposable resource set with its dependencies. | The declared resources reach the intended state. |
| Change review | Review a proposed configuration change before applying it. | The operator can identify the intended resource changes. |
| Drift exercise | Introduce a safe disposable configuration difference. | The team can explain detection and reconciliation behaviour. |
| Removal plan | Remove the disposable resource set using the documented process. | Resources and retained state are handled as intended. |

Scope and architecture
Infrastructure Manager runs Terraform-based deployments as a Google Cloud service; Terraform can also be operated through other CLI or hosted workflows. Decide who should own execution, state and credentials before comparing the two arrangements.
Declarative resource tools share an infrastructure-management goal, but their languages, execution models and state responsibilities differ. A Kubernetes controller, a cloud control plane and a Terraform workflow are distinct operating arrangements.

Cost and migration planning
For Google Cloud Infrastructure Manager, include managed execution and provisioned cloud resources. For HashiCorp Terraform, include selected Terraform offering and provisioned resources. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.
Recreate a disposable resource group with its dependencies, then test change review, drift handling and removal. Confirm how existing resources are adopted and how state and credentials are protected before a production migration.
