Three-tier serverless dog breeds app using Route 53 DNS, CloudFront CDN, and S3 static frontend for presentation. API Gateway routes GET /dogs requests to Lambda GetDogBreeds functions that auto-scale and query a highly available DynamoDB table. This architecture eliminates server management, scales automatically with demand, and reduces operational overhead while maintaining high availability across us-east-1. Fork this diagram on Diagrams.so to customize for your own serverless APIs, adjust Lambda concurrency limits, or add additional endpoints. Consider adding CloudWatch alarms and X-Ray tracing for production observability.
