The number of devices connected to the Internet, including the machines, sensors, and cameras that make up the Internet of Things (IoT) will reach 41.6 billion by about 2025, IDC predicts.
Those connected IoT devices will generate 79.4 zettabytes (ZB) of data in 2025.
Some might call that forecast optimistic or aggressive, but Cisco believes IoT devices could represent as much as half of all connected devices, while driving about six percent of traffic, by about 2022.
IDC projects that the amount of data created by connected IoT devices will see a compound annual growth rate (CAGR) of 28.7 percent to 2025. Notably, most of the data will be generated by video surveillance appliances in the near term, growing to include industrial and medical devices over time.
While the video surveillance category will drive a large share of the IoT data created, the industrial and automotive category will see the fastest data growth rates over the forecast period with a compound annual growth rate of 60 percent, IDC estimates.
