On the Amazon Premium: "There’s a lot of spend in that bucket. The biggest line item is the million dollars per year we spend storing 4.5 petabyte worth of files. We used to store these files ourselves, across three physical data centers for redundancy and availability, but the final math and operational hassle didn’t pan out. So now we’re just on S3 with a multi-region redundancy setup." "I do appreciate the youthful incredulity of thinking you can save us a million dollars a year by pointing to a hard-drive rack . It’s good to question the fundamentals! And we’ve done just that. Spreadsheets up the wazoo. We don’t spend a million dollars with glee. But you can try to cut corners on redundancy and availability, and then you can see how much leniency your customers will show you when you lose their files and have to explain yourself. I’m the one who has to say sorry! So I have to be able to look at our setup and believe we did everything possible to keep our customer’s data safe, and then some. This is that."
