Nobody said it eliminates problems, but moving to the cloud doesnt either, it just hides them away. If that's what you want, that's OK, but at the same time, don't expect much sympathy when you make a blog-post like this and bitch about the lack of transparency on a system you don't manage. You may want to give up control of your infrastructure to someone else, but my personal (not statistical, mind you) experience is that you end up with less control, for more cost.
I have my primary services spread across 3 separate datacenters (AZ's), and backup services across 3 separate AZ's in a region on the opposite side of the country. I pay far less than I would if I put my equipment in only 3 datacenters (2 primary + one secondary) since most of my backup infrastructure is powered off.
And I have far more control than I had with colocated equipment, if I find I need to scale up my services by 2X, 5X or 10X, all it takes is a little more money during the time I need the extra hardware (i.e. end of month processing, plus holiday shopping season), I don't need to order hardware a month or two in advance and pay for it all even when I don't need it.
What I used to pay for my network infrastructure alone (hardware + support + network engineers) pays for most of my entire AWS compute infrastructure.
