2988 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.

  1. Platform as a Product intermediate Multiple choice

    An internal deployment platform with six engineers serves 40 product teams. Three versions of its pipeline interface are live - v1 with 22 teams on it - v2 with 15 and v3 with 3. Supporting all three consumes roughly 40% of the platform team's capacity in compatibility work and support, and the team has shipped no new capability for two quarters. Which versioning policy should the platform adopt?

  2. Platform as a Product intermediate

    An internal platform is used by 11 of 40 product teams. Leadership mandates it - every team must be migrated by the end of next quarter and the alternative paths are closed. The platform team has 6 engineers. What happens over the following two quarters?

  6. Platform Engineering beginner Multiple choice

    A platform injects a log-shipping sidecar with a 128 MiB limit into every pod. During an evening peak the sidecar's in-memory buffer grows faster than it can flush, the pod exceeds its limit, the kubelet kills the container and a product team's checkout service drops requests for eleven minutes. Whose reliability budget is spent and what does that imply about how the platform ships that sidecar?
