Of course... military has the money (the $500 hammer?) to have
redundancy on their redundancy. Business installations normally can't
justify those costs.
However, I think if we looked close we both might be surprised at all
the various baskets AWS has behind the scenes. But like any basket
collection, there are always single points of failure.

You’ve just described what the mainframe does for an organization. But, I don’t
want every organization to have its eggs in one basket any more than I want
every nuclear weapon in one silo.

I don't agree (surprise!) I've always advocated putting all your eggs in
one basket, and then taking really good care of that basket with
backups, DR, procedures, dual this, dual that, etc.

This paragraph concerns me.
One of the founding principles of the early Internet design was
decentralization – by design, a single fault would not be able to take out
everything. In a way, today’s reliance on large cloud providers removes the
benefits of decentralization; we rely on the scalability, cost effectiveness,
and flexibility of today’s SaaS and Cloud offerings yet we are potentially
putting all of our eggs into one basket. This same statement applies to CDNs,
as seen with the recent Akamai outage from this past summer.
This was one of the drawbacks we experienced when our GM subsidiary (and all GM
subsidiaries eventually) combined into EDS data centers. Charlotte was where
ours was located. If the mainframe went down in Charlotte, multiple GM
subsidiaries were screwed. Costing GM tens of millions in highly paid union
labor twiddling their thumbs.
If an ETSY business owner selling crocheted scarves has a 4 hour outage, it’s
probably not that bad. If an auto plant, bank or brokerage, health care
provider, insurance company, or airline is down for 4 hours, it could be
disastrous.
Clouds aren’t all they’re cracked up to be.
