To be frank, I don't see how this differs from the majority of non-"cloud"
business offerings. Over the years I have had plenty of end-user encounters
with systems where these same problems cropped up.
While cloud based systems offer significant problems, I don't know they move
the complexities anywhere that they wouldn't otherwise arrive: building a
distributed, or non-distributed, highly available system with high transaction
rates is always extremely difficult.
Engineering for robustness in the face of failure ... well, we all know how
many people have trouble writing software in the FOSS and closed spaces that
will handle simple failures like "out of disk space", or "can't malloc"
effectively — doing better on a larger, harder scale is unlikely.

It always has been, although you often find "costs of outages" hidden in
metrics like "Total Cost of Ownership" or cost/risk analysis.

I certainly don't disagree with this, however.
