About This Architecture

AWS serverless web application combining CloudFront, S3, WAF, Cognito, API Gateway, Lambda, and DynamoDB across isolated VPC subnets. Users access static assets through CloudFront and WAF, authenticate via Cognito User Pool, then invoke Lambda functions through API Gateway to query DynamoDB. This architecture eliminates server management, scales automatically, and enforces security boundaries using public and private subnets. Fork this diagram on Diagrams.so to customize subnets, add additional Lambda layers, or integrate SNS/SQS for asynchronous processing.

How do I design a secure serverless web application on AWS with authentication and database access?

This diagram shows a production serverless architecture where CloudFront and WAF protect static assets in S3, Cognito handles user authentication, API Gateway routes requests to Lambda functions, and DynamoDB stores application data—all organized across public and private VPC subnets for security and scalability.
