Your question is Scalable Service Design for Global Events. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you design a highly scalable service to handle a sudden surge in traffic for a global event?
Clarify the service's ML responsibilities, traffic shape, latency and availability objectives before proposing an architecture. Explain how you would scale online inference, separate batch work from request-time work, and preserve service quality during overload. Cover capacity planning, degradation, monitoring, deployment safety, and recovery.
