"For this project, I’m using the AWS Cloud Development Kit (CDK), since it allows me to define my infrastructure in JavaScript, and because it comes with some abstractions that AWS CloudFormation (CFN) doesn’t bring. These abstractions remove much of the boilerplate YAML code I would otherwise have to write myself."
