System design.Now with a find-out phase.
Inherit the incident.
Every scenario is an engineering crime scene. A cache stampede, a write storm with your name on it. You get an architecture that's doomed and must save it. No adult supervision.
Build your defense.
Drop components onto the canvas and tweak them. Half the palette is bait. Every tier and knob has a price tag. The budget is not a suggestion.
Meet the herd.
A discrete-event engine unleashes traffic, tick by tick. Your design either holds or folds, and the engine keeps the receipts either way.
Read the wreckage.
Dropped requests, SLA breaches. Graded, charted, ranked. Cheapest correct design tops the board, fastest breaks the tie. Partial credit is for whiteboards.
