The estimated growth of devices connected to the Internet is staggering. By 2020 Cisco estimates that 99% of devices (50 billion) will be connected to the Internet. In contrast, currently only around 1% is connected today. The sheer numbers as well as the complexity of new types of devices will be problematic. Although traditional computing devices such as personal computers, tablets and smartphones will increase, it is the Internet of Things (IoT) which will grow significantly, to around 26 billion units. That represents nearly a 30-fold increase according to Gartner.
