How does Kubernetes compare to AWS Lambda?
⚡
Quick Answer
Kubernetes orchestrates long-running containerized applications you control end to end; Lambda runs short-lived, event-driven functions the provider fully manages. Kubernetes gives control and portability; Lambda gives minimal ops and scale-to-zero.
Detailed Answer
Choose Kubernetes for complex, always-on, portable, or highly customized systems where you want control over runtime, networking, and cost at scale. Choose Lambda for event-driven, bursty, or low-baseline workloads where you want zero server management. Many architectures use both, and Knative/Fargate blur the line.

Interview Tip
Answer with the decision axis (control/always-on vs managed/event-driven) rather than declaring one universally better.
