It describes deploying an Express.js web framework application on AWS Lambda and API Gateway without a server. The application uses services like AWS Lambda, API Gateway, AWS RDS, AWS S3, and CloudFront. It provides steps for configuring the Express.js app to run on AWS Lambda and calling it through API Gateway.
