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.
