Run the cloud behind a small online store. Real AWS prices, real failure rates, customers who pour in and leave when the site is slow. Every server costs money every hour. Can you keep it up without going broke?
Hi, I'm Ping. I explain what's happening and warn you when something looks risky. The decisions are yours.
Every component is a character. They sweat when they're busy, nap at night and fall over when they fail.
The leaderboard ranks an engineering scorecard: reliability, data safety, security, cost, incident response, delivery and business. It grades what your decisions were expected to cost, not your luck, and the server replays every run to verify it.
Early build: one product (an online store) on AWS us-east-1.
