Think about it in terms of erasure encoding where you can have enough shards on enough hosts. That's how you get the durability.

- ff317 4y agoYeah but that's also incredibly naive. Inevitably there will be some un-calculated-for shortcuts that make all those copies not as failure-independent as they seem. If nothing else, what are the odds some random Amazon engineer makes a software rollout or hardware upgrade mistake and takes out a whole lot of copies in the process?
