AWS Serverless API Architecture

This AWS serverless architecture diagram shows a small HTTP API. Internet traffic reaches Amazon API Gateway, which invokes AWS Lambda. The function reads or writes data in Amazon DynamoDB, handles files in Amazon S3 and sends logs to Amazon CloudWatch. It is a clear starting point for teams documenting an API without servers or a separate application tier.
