Vertical scaling is usually more expensive than horizontal scaling. This is not a surprise. What surprises me is that it’s only $1 more expensive here. I suppose that’s because you don’t get double the number of CPUs in the vertical case.
Well, maybe it's a wrong analogy, but when you see a 1l glass bottle of stuff selling for almost exactly twice the price of a 0.5l glass bottle of the same stuff, then there is something off because glass bottles themselves ain't free either.
Of course, when it comes to bottled water my experience is the bigger bottle is cheaper than the small one!

Yep. Try comparing the price of a 1 L bottle with 1 kg of water to a 1 L bottle with 2 kg of water. Vertical scaling can be very, very expensive.
