2908 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

5 questions in Service Virtualisation.

  1. Service Virtualisation intermediate

    A grocery marketplace in the mould of Instacart integrates with 140 retailer systems for inventory lookup and order injection. A platform engineer proposes building a virtual service for each one so the test suite can run without them. Roughly what does that cost per year to keep faithful and how many of the 140 are actually worth virtualising?
