Vertical scaling is so much more efficient in so many ways, it's nearly unbeatable (for cost and performance.)
Not when you have many workloads and there are lots of things that proves this. But I know you're the master of relentless posting so I'm just respectfully going to bow out 🙂
How does "many workloads" even factor in? Nothing you've mentioned gives a reason for your position. There's no logical reason and nothing in the real world supports that horizontal scaling somehow saves money. This goes against all industry knowledge, common sense and observation. Even your own examples, you pointed out that the factors you were using were wrong and didn't show what you were using them to show. Just posting unsupported random misinformation and "bowing out" before we ask for some explanation just makes it seem like you were just saying those things to say them and don't believe them yourself.
In your last "example", the more workloads you have, the more horizontal scaling wastes money. Vertical scaling specifically crushes horizontal in cost/performance the more numerous and disparate the workloads are. Vertical scaling is where you get the huge cost/performance benefits of shared hardware. And, of course, people trying to make shared hardware look bad with underspec it or misconfigure it and try to say that that makes it bad, but you can underspec or misconfigure anything. Mathematically, vertical scaling works better. It's plain physics, you can't just state that physics aren't real and act like you have special insider knowledge of the universe that no one else has and cannot be demonstrated with real computers.
