Infrastruct
summary
Demo creates a full Ruby on Rails cluster on Amazon EC2 in minutes, using EngineYard-style orchestration, Chef for infrastructure as code, Nanite over RabbitMQ for two‑way command-and-control, and HAProxy plus an elastic IP to elect a master. Configuration runs idempotent recipes from JSON "dna", bootstrapping finishes in 5–10 minutes bootstrap cycles, and a simulated lightning strike triggers a self‑healing cluster that kills the bad node, reclaims IPs and boots replacements via APIs.
