Which service enables you to model a collection of related AWS resources and provision them quickly as code?

• A. Amazon Textract
• B. AWS CloudTrail
• C. AWS CloudFormation
• D. Amazon Polly

Answer: (C)

Modeling a group of related AWS resources and provisioning them automatically from code is the essence of infrastructure as code. The service that does this best is CloudFormation. It lets you author templates in YAML or JSON that declare the exact resources you need, their configurations, and how they depend on each other. When you deploy a template as a stack, CloudFormation provisions all the resources in the correct order, handles updates and rollbacks, and you can reuse the same template to recreate environments quickly and consistently. The other services aren’t designed to manage infrastructure as code: Textract is for extracting text from documents, CloudTrail records API activity for auditing, and Polly converts text to speech.
