A quick intro to AWS Serverless

on YouTube ↗31m

" summary

Quick, practical AWS Serverless notes: AWS Lambda runs Python/Node/Java functions on events with automatic scaling and measured cold starts around two seconds; API Gateway maps REST routes to Lambdas (or S3/DynamoDB/HTTP) with body/header mapping, custom status codes and redirects that require deployment to take effect. Demo builds a timestamp lambda and a /hello endpoint that redirects via a Location header and works after deploy. Deploy tools include Zappa and Chalice. Pricing: 1M free requests/month and 400 GB-seconds free, then pay per request and per GB-second.
