What if you could build your next serverless application without a single Lambda function? Let me introduce you to the functionless model: a serverless architecture that emphasizes event-driven, service-based design by connecting AWS services directly, eliminating the need to package, deploy, and manage countless individual Lambda functions.

In this demo, you’ll see a functionless application in action, built with AWS CDK. Instead of writing custom code in intermediary Lambda functions, the application uses direct integrations between AppSync, Step Functions, EventBridge, and DynamoDB to handle all business logic and data flow.

You’ll walk away understanding how to reduce operational complexity, improve performance, and lower costs by leveraging native AWS service integrations. All while building more maintainable serverless architectures, and having a bit of fun in the process.
