How would you answer an interview scenario involving Kubernetes autoscaling?
For an interview scenario involving Kubernetes autoscaling, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Kubernetes supports workload and node scaling through mechanisms such as Horizontal Pod Autoscaler and Cluster Autoscaler. In this scenario, an API receives burst traffic and a worker consumes a message queue. Explain which scaling signals you would use for each workload. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
