Great read! Spreading the load across thousands of machines is exactly what makes companies like Netflix survive traffic spikes. Do you think there's a point where horizontal scaling alone isn't enough?

Yes. There's a point where just throwing more machines at the problem doesn't fully solve it anymore.

Horizontal scaling gets you very far, but at massive scale, you need a combination of smart architecture, vertical scaling, and careful system design.
