> This came out to about a 2x savings over AWS.

Is that a typical way to describe cost savings? I would have said 1/2 the cost of AWS. It almost sounds like cloudflare would pay them money (e.g. you go to the store and see something marked 200% off, so you get paid to buy it, like when oil prices went negative).

Related: I've always found the 2x, 10x, etc notation confusing. Does a 2x improvement mean a 100% increase (e.g. 10 -> 20) or a 200% increase (e.g. 10 -> 30)? Would someone ever say a 1x improvement or a 0.5x improvement?

It's funny how your first paragraph makes it clear you're not confused about this at all.

2x savings means you need to double the new price to get the old

10x savings means multiple new price by 10x to get old

59x savings...multiply by 59.

Yeah, I could guess based on context. I would prefer notation that's clear on its own without needing to look at context. "1/2 the price" is clear on its own.

And it still makes me feel nervous that 3x improvement = 200% increase. It seems to me like a big opportunity for misunderstanding.
