2827 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.

92 questions in Platform Engineering.

  1. Abstraction Level Choice advanced

    A platform must choose how much of the underlying infrastructure to abstract. What decides the level?

  2. Abstraction Level Choice advanced

    A platform team must decide how much to abstract the underlying infrastructure. What goes wrong at each extreme, and how do you choose?

  3. Abstraction Level Choice advanced

    An internal platform must decide how much of the underlying infrastructure to hide. What determines the right abstraction level, and what happens at each extreme?

  4. Abstraction Level Choice advanced

    Your platform abstracts Kubernetes entirely — teams write a short manifest and everything is generated. Now every production incident escalates to the platform team. What is happening?

  5. Cluster Architecture advanced

    A Kubernetes platform shows GPU utilisation below 40% because jobs request whole nodes. How should bin packing, gang scheduling, preemption, partitioning and queue-based admission raise utilisation without harming priority jobs?

  6. Cluster Architecture advanced

    A Kubernetes upgrade to 1.24 removes a deprecated node label. Within minutes the cluster's pod network loses all routes and stays down for over five hours, and the configuration responsible is not in any repository. What kind of dependency is this, and how would you have found it beforehand?

  7. Cluster Architecture advanced

    A platform must decide between one large cluster and many small ones. What are the trade-offs?

  8. Cluster Architecture advanced

    How many Kubernetes clusters should an organisation run, and what decides the boundaries?

  9. Cluster Architecture advanced

    How should compute clusters be structured for a platform running many teams' workloads with very different profiles?

  10. Cluster Architecture advanced

    Your platform team of five spends nearly all its capacity upgrading control planes across 38 Kubernetes clusters. How did this happen and how do you fix it?

  11. Container Image Strategy intermediate Multiple choice

    A critical CVE in a widely-used C library is announced at 09:00. You have 200 services in containers, each built by its own team's pipeline. Which approach patches the fleet fastest?

  12. Container Image Strategy intermediate

    A platform must define a container image strategy for many teams. What decisions matter, and what is the security constraint?
