I agree with you. I mostly work in enterprise and understand that it has different needs and ROI requirements. However, my personal mindset is that computers and networks are really really fast now and it's a tragedy that most of these gains are nullified due to unoptimized layers of abstraction or over-architecting. So it's a welcome sight to read about well-designed infrastructure like this.
It happens because business are optimizing for resources that are ultimately more expensive or slower, which is staffing levels and the ability to respond to the market so the business can grow or survive longer. Inefficient computing architecture as a side effect is a worthwhile tradeoff in light of that to them.
