Scalability Is Not About Your Code — Here's What It Really Means

Good take, but I think it’s both. Infra handles the load, but good architecture makes sure you don’t waste it. You can throw servers at a bad system and still crash. Real scalability is using resources efficiently and having enough of them.

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?
