This document discusses the future of cloud computing and how it is becoming more open. It notes that technology adoption is now bottom-up, with developers choosing tools like Shadow IT rather than IT decision makers. These Shadow IT tools are often more open than traditional options, using open source platforms and multiple runtimes. The future of cloud platforms is moving towards being more open as well, from closed and single-runtime in the past to open and supporting multiple runtimes now. The document advises that to manage Shadow IT, companies should make official open platforms available that are easy to use, rather than trying to stop its adoption, and then monitor usage of those platforms.
