About This Architecture

AWS serverless dog breeds API demonstrates a three-tier architecture combining S3 static hosting, API Gateway, Lambda functions, and DynamoDB. User browsers fetch static content from S3, then invoke API Gateway endpoints that trigger Lambda functions to query dog breed data from DynamoDB. This pattern eliminates server management, scales automatically with demand, and charges only for actual usage—ideal for low-traffic or variable-load APIs. Fork this diagram on Diagrams.so to customize endpoints, add authentication, or extend with additional Lambda functions. Consider adding CloudFront caching in front of S3 for global content delivery and reduced latency.

How do I build a serverless REST API on AWS with S3, API Gateway, Lambda, and DynamoDB?

This diagram shows a three-tier serverless API where users access a static website hosted on S3, which calls API Gateway endpoints that trigger Lambda functions to query dog breed data from DynamoDB. Each tier is independently scalable and you pay only for actual invocations and data storage, making it ideal for variable-traffic APIs.
