Kenton Varda's mental models

Their wordsThe worst thing an application can do is tell the user that their action was successful when it wasn't. If, for some reason, a write cannot be completed, then it's imperative that the application presents an error to the user, so that the user knows that something is wrong and they'll have to try again or look for a fix.

Their wordsSecond, part of the promise of serverless is that developers shouldn't have to worry about updating their stack. If we start letting people pin old versions, then we have to start telling people how long they are allowed to do so, alerting people about security updates, giving people documentation that differentiates versions, and so on. We don't want developers to have to think about any of that.

Their wordsEven the best benchmarks have bias and tradeoffs. It's difficult to create a benchmark that is truly representative of real-world performance, and all too easy to misinterpret the results of benchmarks that are not.
