2667 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.

  3. Judgement Under Uncertainty advanced

    Review this decision record. It chooses a single Postgres primary over sharding for an orders service measured in production at 1200 writes per second, lists three rejected alternatives with reasons, and ends with "Revisit in 12 months". What would you change, what would you leave alone, and what one line makes the decision reviewable?

  4. Pattern Recognition advanced

    An experienced architect recognises a familiar pattern and proposes the solution that worked before. What are the risks, and how are they managed?

  5. Pattern Recognition advanced

    An interviewer asks which architectural analogy you reach for too often. Assume you genuinely do not know the answer. How would you find it from your own written record, and what would you do with the finding?

  6. Pattern Recognition advanced

    Discord's Read States service was fast most of the time but showed latency spikes every two minutes. The pattern looked familiar to anyone who has seen a service under load. The cause published in 2020 was Go's garbage collector scanning a large LRU cache. What does this teach about pattern recognition, and which check would have got there faster?

  10. Research & Evaluation advanced

    A travel-search platform aggregating supplier prices - the business shape Expedia operates in - measures 40 million price updates a day and must choose between a managed search service and running the engine itself. A two-engineer two-week spike would settle it. Work out when buying that information is cheaper than deciding now.
