Serverless Django
summary
Shows how to convert an existing Django app to run on Zappa using AWS Lambda and API Gateway, claiming millisecond ephemeral servers, dramatic cost drops (one example saves ~$1,000/year) and scaling to trillions of events per year. Demonstrates zappa init/deploy, event-driven hooks for S3 avatar processing, scheduled jobs, and zappa.async for long tasks, and covers RDS + VPC setup, DisallowedHost and static-file gotchas, NoDB alternative, Let’s Encrypt/ACM SSL and the S3 infinite-loop pitfall to watch for.
