Forecast storage demand across data centers

Forecast how much storage each of about 100 data centers will need, so capacity can be bought ahead of time. Cover the target and horizon (daily demand, weeks or months ahead), the signals (history, seasonality, launches, growth trends), the models from simple baselines to models shared across data centers, how you handle the cost of under- versus over-forecasting, backtesting, and how the forecast feeds the purchase decision.
