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.

IBM's approach to open technology
For several years, IBM has been recognized as a leader in open technology, from its early work with Apache to its current work across all layers of the cloud stack and application development. This recognition comes on the back of tireless collaboration with fellow industry leaders and clients alike. The case for open is clear: Projects that are managed under open governance have been found to be more successful, have a longer life, and are less risky than proprietary projects. The most successful projects are those that ensure interoperability and portability, and address various other enterprise needs such as security, scalability, and accessibility. IBM isn't just an open source consumer; it is also an ardent contributor to several projects, including Eclipse, Linux, OpenStack, Cloud Foundry, Node.js, Docker, Hyperledger, and many more. The company's ongoing commitment to open technology is viewed as a means to form the very foundation of enterprise systems and solutions.
