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.

6 questions in Technology Architecture.

  1. Technology Architecture intermediate Multiple choice

    A language runtime used by 180 of 240 services leaves vendor support in 14 months. Services are owned by 40 teams with their own roadmaps, and the upgrade is mostly mechanical but breaks in about 15% of cases. Which approach gets the estate upgraded?

    An internal team and a packaged-software vendor both pick the same message serialisation format this quarter. Two years later the internal team replaces it in a single sprint. The vendor still supports it and expects to for another decade - an ERP vendor in SAP's position has customers whose 12-year-old integrations must keep working across a major release. Nothing about the technology differs. What makes the same choice a different decision for each of them?

    On 19 July 2024 a content update to a security agent crashed millions of Windows hosts worldwide. CrowdStrike's root cause analysis attributes it to a logic error in channel file 291, timestamped 04:09 UTC, affecting hosts that received that version. Microsoft's crash-report-derived estimate was about 8.5 million devices. What is the enterprise architecture lesson, and what would you change in your own estate?
