Rails in the Cloud

on YouTube ↗38m

" summary

A small Rails photo app uploads directly to Amazon S3, queues conversion jobs on SQS, and records status in Amazon SimpleDB while serving results through CloudFront. The claim: minimal upfront investment and on‑demand scaling by splitting web and worker pools. The demo actually runs two web servers and two processors, creates JSON jobs, processes images with ImageMagick, and updates SimpleDB attributes so the page shows converted files as they finish.
