This video from AWS re:Invent 2023 showcases how Amazon's Buy with Prime team leveraged AWS CDK to rapidly scale their cloud architecture. The speakers explain how they created reusable, secure-by-default CDK constructs to standardize infrastructure deployment across services. They demonstrate examples of custom constructs for DynamoDB and Fargate, highlighting how this approach saved an estimated 50 years of development time. The presentation provides valuable insights for organizations looking to improve developer productivity and consistency when building cloud infrastructure at scale using AWS CDK.
