Your question is Capacity Planning and Scaling. 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 capacity plan for a rapidly growing customer deployment and decide when to scale infrastructure for Datadog-based monitoring?
Provide a hands-on design using Datadog Infrastructure Monitoring, Metrics, Monitors, Service Management, and Observability Pipelines. Explain the telemetry required, forecasting method, scaling signals, alert thresholds, rollout process, cost controls, and failure recovery. Include an implementation outline with infrastructure-as-code, dashboards, and validation steps.
