Key points

• CloudFormation declares data-pipeline resources, dependencies, parameters, and permissions in version-controlled stacks.
• Change sets and stack lifecycle make environment drift and deployment impact reviewable.

Best-known use cases

• Provision complete data-pipeline stacks from version-controlled templates.
• Promote consistent resources and permissions across environments.

What candidates often confuse it with

• CloudFormation is the declarative IaC model; SAM specializes it for serverless resources and CDK synthesizes templates from code.

Key takeaway

Choose CloudFormation when the pipeline needs reviewed, repeatable infrastructure across environments.
