Ruby in the Cloud
summary
A Rails app moves from a single office server to EC2 and is running across multiple disposable instances in about 30 minutes to migrate, using a payload-based launch script plus provisioning. Monitoring and restart come from God, scheduled jobs use Rufus scheduler, queues and storage use SQS and S3, DNS is updated via DD client, and the cheapest instance runs around 10 cents per hour. Deployment uses Capistrano/Vlad and custom Ruby glue that mostly works.
