AWS CloudFormation

A standalone path through CloudFormation, AWS’s built-in infrastructure-as-code service. Beginner covers the model (templates, stacks, resources), template anatomy in YAML, parameters/mappings/outputs, and the deploy loop. Intermediate is the working toolkit: change sets and safe updates, intrinsic functions and pseudo-parameters, nested stacks and cross-stack references, and drift detection. Advanced goes deep: custom resources and macros, StackSets across accounts/regions, guarding with cfn-lint/cfn-guard/cfn-nag, and secure delivery in CI/CD. Real templates and CLI output throughout; each level ends with a self-test feeding a rotating final exam.
