I do wish that when people write about optimization that they would then multiply by usage, or something similar.

Another way is to show CPU usage over a fleet of servers before and after. And then reshuffle the servers and use fewer and use the number of servers no longer needed as the metric.

Number of servers have direct costs, as well as indirect costs, so you can even derive a dollar value. More so if you have a growth rate.

How? You can give specific examples and then people make the same complaints because it isn't relevant to their use case. It's fairly easy to extrapolate the numbers to specific cases. We are humans, and we can fucking generalize. I'll agree there isn't much to the article, but I find this ask a bit odd. Do you not have all the information to make that calculation yourself? They should have done that if they're addressing their manager, but it looks like a technical blog where I think it is fair to assume the reader is technical and can make these extrapolations themselves.
