Modern cloud backend data processing is 5 9s reliable too, for very core stuff, not all the app frontends and minor features.

Modern cloud “5 nines” isnt a promise of availability but a promise to get some store credit each month when it inevitably fails (adjusted down for usage because you dont use all that capacity you pay for so we just credit for the percentage you do).

The trick is to make sure when you promise 5 9s to your customer that you build in the same bullshit clauses so you dont get left holding the bag.

Its gross

You don't even have the assurance that the RAM is ECC on cloud...
