Summary

AWS CloudFormation models, provisions, and manages related AWS and third-party resources as infrastructure as code. You describe AWS resources and their properties in YAML or JSON templates, then use those templates to manage stacks. Change Sets preview proposed changes, including possible resource deletion or replacement, and Drift Detection identifies changes made outside CloudFormation. StackSets provision a common set of resources across multiple AWS accounts and Regions. Authoring options include AWS CDK, which supports TypeScript, Python, Java, and .NET, and AWS SAM, whose shorthand YAML for serverless resources is converted to CloudFormation syntax during deployment. The Registry supports third-party resources and modules, and stacks can be updated from remote Git repositories. IAM can control access, while CloudTrail logs API calls. CloudFormation data is encrypted at rest and service communications use encrypted channels; AWS recommends TLS 1.3 and requires TLS 1.2. The service itself has a free plan, but AWS resources created through it are billed at their standard rates. Third-party provider and custom hook operations may also incur charges.

Who it is for

It suits teams managing AWS infrastructure as code, from individual instances to complex multi-Region applications, and automating infrastructure templates in CI/CD workflows. It can also suit users who need cross-account deployments or previews of proposed stack changes.

What is good

Templates use YAML or JSON.
Change Sets preview possible deletions or replacements.
StackSets deploy across accounts and Regions.
Drift Detection tracks outside changes.
CDK supports four listed programming language options.

What to know first

Created AWS resources incur standard charges.
Third-party provider and custom hook operations may incur charges.
TLS 1.2 is required; AWS recommends TLS 1.3.

Verdict

CloudFormation brings template-based provisioning, change previews, drift tracking, and multi-account deployments together for AWS resources. The service itself is free for AWS and Alexa resource providers, but the resources it creates and some other operations may be billed.
