The serverless startup
summary
A small CMS is built using AWS Lambda, API Gateway and DynamoDB where API calls trigger Node.js Lambdas packaged with npm deps and billed per 100 ms so you pay essentially zero when idle and stay in the generous free tier. Typical API roundtrips through Lambda and DynamoDB measure 300–600 ms, while cached JSON served from S3/CloudFront hits 30–50 ms. Cognito provides OAuth sign‑in and temporary IAM creds, CloudWatch stores logs and alarms, and versioned Lambda deployments map to production/test.
