Which AWS service lets you define and deploy consistent, repeatable infrastructure configurations?

AWS CloudFormation allows you to define your AWS infrastructure as code using templates. These templates can be used to provision and update a collection of AWS resources in a consistent and repeatable manner, ensuring your environments are identical. AWS CodeDeploy is a service that automates code deployments to various compute services. AWS CodeBuild compiles source code, runs tests, and produces deployable software packages. AWS Systems Manager helps you manage your AWS resources and on-premises servers, but it doesn't primarily focus on defining and deploying infrastructure as code for initial provisioning like CloudFormation does.
