2627 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.

  2. Layered Architecture beginner

    A team's rule is that the domain layer must not import the persistence layer. Today the rule lives in a wiki page and in code review. What changes when the same rule becomes a check that fails the build, and what does the violation count over time tell you that today's count does not?

  3. Sidecar & Ambassador beginner Multiple choice

    A platform team rolls out sidecar proxies so every service gets mTLS without code changes. A month later an auditor captures traffic and finds one service still sending plaintext credentials to an external payments SaaS. The sidecar is running and healthy. Why is that traffic not encrypted by the mesh?
