Whenever you're ready, walk me through how you'd approach this.
How would you scale the application?
Asked in the Operational and Engineering Excellence stage. Treat this as an end-to-end ML system design discussion. Begin by identifying the missing product, traffic, data, latency, availability, and cost requirements, then explain how those requirements determine the architecture. Cover online and batch workloads, model serving, data growth, deployment strategy, monitoring, and failure recovery. Do not assume a particular application domain. State your assumptions clearly and explain how you would validate them.
