AWS CloudFormation: With AWS CloudFormation, review a proposed configuration change before applying it.

The operator can identify the intended resource changes.

Drift exercise

Can the team introduce a safe disposable configuration difference?

Azure Resource Manager: With Azure Resource Manager, introduce a safe disposable configuration difference.

AWS CloudFormation: With AWS CloudFormation, introduce a safe disposable configuration difference.

The team can explain detection and reconciliation behaviour.

Removal plan

Can the team remove the disposable resource set using the documented process?

Azure Resource Manager: With Azure Resource Manager, remove the disposable resource set using the documented process.

AWS CloudFormation: With AWS CloudFormation, remove the disposable resource set using the documented process.

Resources and retained state are handled as intended.

Scope and architecture

Resource Manager and CloudFormation are cloud-specific deployment control planes. Compare the resource types, change-review process and operating model required in Azure or AWS rather than assuming templates translate directly between them.

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 Azure Resource Manager, include provisioned Azure resources and supporting tooling. For AWS CloudFormation, include provisioned AWS resources and applicable extension usage. 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.
