There is no doubt that IoT is here to stay, mainly in areas such as manufacturing and transportation where there are clear benefits to connecting devices such as energy efficiency. Industrial IoT (IIoT), in particular, is being increasingly adopted as early adopters have successfully used the technology to remove inefficiencies, prevent errors, and optimize yields with real-time adjustments. …
Here is one model to think about how IoT projects can grow in complexity, and correspondingly, value: the IoT Extensibility Framework, taken from The Amazon Way on IoT. This describes four increasingly complex levels of IoT projects.
