That’s too big a caveat to breeze by without a huge justification. If you look at the full cost that 1-2 orders of magnitude for many places goes negative and is a smaller margin for almost everyone else unless you have some combination of very high usage to amortize your staff costs over and/or the ability to change the problem (e.g. beating S3 with fewer copies or using cold storage, having simpler or slower ops or security, etc.).
It can be done but I’ve seen far more people achieve it through incomplete comparisons than actual measured TCO, especially when you consider the first outage where they’re down for a week longer because they learned something important about how data centers can fail.
