In one sentence
AWS infrastructure as code that creates and manages repeatable resource stacks from declarative templates.
Key points
- Templates use YAML or JSON to declare resources, parameters, conditions, mappings, and outputs.
- A Stack manages resources as one unit, while Change Sets preview updates and rollback handles failures.
- Drift Detection finds differences between templates and actual resources; StackSets deploy across accounts and Regions.
Exam takeaway
Console is manual, CLI is command automation, SDK is application integration, and CloudFormation is declarative infrastructure management.
