What Happens When Your AWS Application Receives 10,000 Requests at Once?

Imagine building an application that works perfectly during development.

Your API responds quickly, database operations succeed, and everything looks good during testing.

Then your application goes viral.

Suddenly, thousands of users try to access it simultaneously. Requests start timing out, database connections become exhausted, and your application struggles to keep up.

The interesting part? Your application might not have a bug at all.

It might simply be unable to handle the sudden increase in demand.
