Serverless Scales. Your App Still Crashed. It starts with a spike — maybe your app gets featured in a newsletter, or your product hits the front page of Hacker News. Suddenly, thousands of users flood your service. But you're ready, right? You're serverless. AWS Lambda will scale up! DynamoDB has on-demand mode!

Then… things slow down. Requests hang. Timeouts increase. Your dashboard goes from green to orange to red. Your app, once full of promise, is now full of users who can’t do anything.

What happened?

Serverless scaled but your problems scaled faster.
