It is.
The cloud fanbois will tell you until their blue in the face that its not.
I fully accept that the cloud is great for bursty workloads where you're doing nothing and then suddenly half the planet needs your service for a couple of days. That is clear.
But if you've got a reasonably stable baseload running 24x7x365 and a few modest bursts here and there then honestly people need to do the math, because if you look at beyond the short-term figures, the cloud tends to work out much more expensive than colo if you look at for example a three-year period.
Most people don't need the scale the cloud gives. They think they do, but really most people will never grow to FANG scale as much as they may dream it !
