Predictive Cloud Computing for professional golf and tennis, Part 8: Forecasting
In professional golf and tennis tournaments, athletes welcome any competitive advantage. Looking beyond the current time horizon into the future allows players to position their rackets before the ball arrives and to select the appropriate club based on future weather conditions. The Predictive Cloud Computing project is no different. Time series algorithms project web origin traffic trends into the future so that cloud services can be provisioned or de-provisioned to anticipate sporting content demand. Sinusoidal patterns with a trend, cycle, and level that have been learned from historical data at rest are ensembled together with real-time demand patterns. The combination of InfoSphere Stream, InfoSphere BigInsights, RabbitMQ, WebSphere Java Application, Apache math commons, and custom algorithms have produced forecasts with an 18.44% mean absolute percentage error (MAPE). As a result, provisioning cloud services for future demand loads has saved thousands of compute minutes.
