How would you answer an interview scenario involving serverless architecture in Cloud Architecture?

For an interview scenario involving serverless architecture, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Serverless platforms run application code on managed infrastructure with event-driven scaling and reduced server management. For production, design around execution limits, idempotency, observability, concurrency, cold-start tolerance, and managed integrations. 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.
