AWS CDK

AWS CDK lets you define cloud infrastructure in TypeScript with real programming constructs — loops, conditionals, abstractions. It generates CloudFormation under the hood, giving you the reliability of CloudFormation without the YAML suffering.

The L2 and L3 constructs encode AWS best practices. Creating a VPC with public and private subnets, an ECS service with load balancing, or an S3-backed CloudFront distribution takes a few lines of code instead of hundreds of lines of YAML. We use CDK for all AWS infrastructure and the productivity gain over raw CloudFormation is substantial.
