2948 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.

    Four years ago a platform team adopted a cloud vendor's landing-zone reference architecture whole: hub-and-spoke network, three subscription tiers, a central firewall appliance, a shared CI account. The estate turned out to be three products and 40 engineers. The appliance adds a 12 ms hop to every internal call and caused two of the last five incidents. Auditors were told the architecture "conforms to the vendor reference". Sequence the migration to a simpler topology without losing the audit story.
