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.

  9. Developer Environments intermediate

    A payments change passes its per-PR ephemeral environment and staging. Twenty minutes after the production deploy checkout p99 goes from 300 ms to 9 s and the database shows lock waits on one table. The ephemeral environment ran the same image and the same migration. What failed and which decision made the failure possible?
