The Internet of Things (IoT) is rapidly emerging all around us. This is driven by a multitude of factors related to availability of standards, platforms, skills, processing power, low costs sensors and much more. The essential concept to understand is that not only the availability of these factors is critical to have success, so is the concept of availability of data. As we are constructing virtual models of the physical world and creating digital twins of products, the services and data of these must be available all the time. This places new requirements to the reliability of the products, networks, and cloud services, such that the value created by the IoT system is available, when the end clients need it. Hence, availability is a key driver for the IoT. In this report a detailed look into the availability of the individual factors is described one by one.
