Internet of Things (IoT) can be viewed from three system perspectives. It is called IoT when it is viewed from the inter-networking of things, Cloud of things from computing on the data gathered by things and Web of Things (WoT) from representation of things. This paper surveyed industrial readiness for IoT from these three perspectives. For each perspective, related companies and their solutions are studied. Through this survey, we find that IoT begins its permeation into our daily lives, from consumer to industry, from academia to government, from counties to the globe with great impetus. Almost all major semiconductor companies and software companies provide their solutions to IoT.
