A few years ago, [IDC] made headlines by predicting that the total amount of digital data created worldwide would mushroom from 4.4 zettabytes in 2013 to 44 zettabytes by 2020. Now, IDC believes that by 2025 the total will hit 180 zettabytes. The astounding growth comes from both the number of devices generating data as well as the number of sensors in each device… approximately 11 billion devices connect to the Internet now. The figure is expected to nearly triple to 30 billion by 2020 and then nearly triple again to 80 billion five years later.
