All are already in widespread use…

Internal resources


Many new resource services already are API-based

Developers prefer to use "APIs even with the added "

work of learning APIs versus ESB approaches

App Consumption

•  API adaptations needed for apps •  Enable developers for business •  Security for app-to-API •  App and behavior analytics

API Exposure

•  APIs architected for abstraction •  Enable developers for API use •  Security for API-to-backend •  API Analytics

Visibility into business and operations Using APIs and data analytics to provide new visibility and insight into their digital ecosystems, customers, and business. As business moves from large batch feeds to transactional consumption model •  APIs deliver high volume information; Apigee provides operational stability for large scale •  Analytics for operations: capacity management, predicting load … •  Analytics for business: predicting what people will want to do with information and data


“If I deliver somebody a data feed it’s gone, I don’t know what they are doing with that data. I don’t know how they are consuming it. When they come to us directly and consume it through APIs we get visibility – what data are they pulling, how freqently, and what are they doing with it.” " ~ Greg Goff, CTO Morningstar
