The recent
EMC2-sponsored IDC study anticipates that the digital universe – a measure of all the digital data created, replicated, and consumed in a single year – will reach 40ZB by 2020, which is equivalent to 5,247 GB per person worldwide.
In just the past two years, the digital universe has doubled to 2.8 zettabytes – a zettabyte (ZB) equals a trillion gigabytes. And, the IDC survey, titled “Big Data, Bigger Digital Shadows, and Biggest Growth in the Far East,” projects that the digital universe will continue to double every two years between now and 2020. According to the study, a major factor behind the expansion of the digital universe is the growth of machine-generated data, which is expected to increase from 11% as recorded in 2005 to more than 40% in 2020.

The Digital Universe in 2020: Big Data, Bigger Digital Shadows, and Biggest Growth in the Far East
The Geography of the Digital Universe
It is possible to assign a place of origin to digital information and chart the map of the digital universe.
Big Data in 2020
IDC believes only 3% of the potentially useful data in 2012 is tagged, and even less is analyzed.
Information Security in 2020
Only about half the information in the digital universe that needs protection has protection.
Cloud Computing in 2020
There won't be one cloud, but many, bounded by geography, technology, different standards, industry, and perhaps even vendor.
Call to Action
Are you ready to create, consume, and manage 40 trillion gigabytes of data?
