2988 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. SLO Monitoring intermediate Multiple choice

    A checkout API has a 99.9% availability SLO and the team must decide where the indicator is computed from. The candidates are load-balancer access logs, in-process server metrics, the mobile client's own reporting, and synthetic probes. Which should be the primary source?

    A food-delivery platform in Zomato's mould pushes order-status events to restaurant tablets and to customers through a queue-backed webhook fleet. The complaints are that status arrives late rather than that it never arrives. Which indicator should the SLO be written on?

    A new telemetry service is rolled out across a large Kubernetes fleet to improve visibility. Within minutes, DNS-based service discovery degrades across the cluster and a substantial outage follows, lasting hours. OpenAI published this for 11 December 2024. Reason backwards: what failed, which design decision made it possible, and why was recovery slow rather than a simple rollback?
