      Where does engineering rep come from? Here's a Google engineer slagging on Amazon engineering, which they say mediocre. I don't think this is an unusual opinion, I've heard this from people both inside and outside of Google. Google has the best engineering, Amazon is mediocre.pic.twitter.com/EPLwjpUytT

      "Amazon clearly does not compete by hiring the best engineers. Rather, they compete by throwing money at the problem and undercutting everyone else, getting by with mediocre engineering." -- googlemike

      I'm probably going to regret tweeting this, but I think we're 100% fine with Google folks thinking this, but they would never be comfortable the other way around. And that's the difference.

      I'm also going to regret tweeting this, but I can think of at least 3 "big" Google papers (Maglev, Spanner, ALTS) with designs we had rejected years and years earlier, with seemingly no commentary on the problems that we had discovered. Anyway, we prefer to ship and keep on :)

          Where can we read why they were rejected?

          We rejected a Maglev-like design because probabilistic LB doesn't work for the vast majority of workloads. Most customers have only 2 LB targets, they're also often slow, and subject to garbage-collection pauses. Probabilistic LB increases utilization way too much.

          Also, say what you will about Chime, but Amazon has a significantly more clear strategy in the messaging space ;)

          Thanks for proving that not only Google engineers can be pretentious. (opinion mine, not my employer's)

          One thing that you can salvage out of his tweet is that Amazon raised the meta-level of the whole industry with virtual-machines-as-a-service. Like there's plenty of discussion happening at higher levels of the stack, but VMaaS is truly the desired baseline in the whole industry.
