Interesting article, though I wish there were some more concrete numbers, particularly around latency - what's the latency on normal S3, what is it on S3 Express One Zone, and what latency/throughput is necessary for the kind of systems he's talking about? Some cost estimates would also be interesting, though that would be harder to figure out.
