This document discusses how innovation is fostered in open ecosystems with low experimentation costs, enabled by cloud technologies. It notes that in cloud environments, resources are more granular and dynamic, assembling and reassembling faster to enable diversity. It emphasizes that APIs form the connective tissue of cloud deployments, and managing connections via APIs is critical. The document advocates for building systems that are more granular, diverse, open, interconnected, and agile by establishing a flexible API-centric architecture and managing the lifecycles of cloud services.
