Modal's modal-http: Serving Web Functions on Serverless Infrastructure

Modal built modal-http, an HTTP and WebSocket stack that lets its serverless functions accept web requests, with full WebSocket support recently completed. Unlike AWS Lambda's 15-minute and 50 MB limits, Modal containers can use up to 64 CPUs, 336 GB of memory and 8 Nvidia H100 GPUs, so the team translates HTTP into function calls rather than fronting containers with a conventional reverse proxy.
