Serverless Contact Form — Lambda, API Gateway, DynamoDB, and SES

Overview

The contact form on bonefishsoftware.com is fully serverless — no EC2, no always-on server. A visitor submits the form, the request hits an API Gateway HTTP API, a Python Lambda function validates and stores the submission in DynamoDB, then sends an email notification via SES. Cost at low volume: effectively zero.

Flow

Infrastructure — AWS SAM

The contact API is deployed using AWS SAM (Serverless Application Model), a CloudFormation extension that simplifies Lambda + API Gateway resource definitions.
