[/caption] The proliferation of devices such as PCs and smartphones worldwide, increased Internet access within emerging markets and the boost in data from machines such as surveillance cameras or smart meters has contributed to the doubling of the digital universe within the past two years alone — to a mammoth 2.8 ZB. IDC projects that the digital universe will reach 40 ZB by 2020, an amount that exceeds previous forecasts by 14 percent. In terms of sheer volume, 40 ZB of data is equivalent to:
- There are 700,500,000,000,000,000,000 grains of sand on all the beaches on earth (or seven quintillion five quadrillion). That means 40 ZB is equal to 57 times the amount of all the grains of sand on all the beaches on earth.
- If we could save all 40 ZB onto today?s Blue-ray discs, the weight of those discs (without any sleeves or cases) would be the same as 424 Nimitz-class aircraft carriers.
- In 2020, 40 ZB will be 5,247 GB per person worldwide.
? Rapid expansion of the digital universe: IDC projects that the digital universe will reach 40 ZB by 2020, an amount that exceeds previous forecasts.
- The digital universe will double every two years between now and 2020.
- There will be approximately 5,247 GB of data for every man, woman and child on earth in 2020.
- A major factor behind the expansion of the digital universe is the growth of machine generated data, increasing from 11 percent of the digital universe in 2005 to over 40 percent in 2020.
? Large quantities of useful data are getting lost: The promise of Big Data lies within the extraction of value from large, untapped pools of data. However, the majority of new data is largely untagged file-based and unstructured data, which means little is known about it.
- In 2012, 23 percent (643 exabytes) of the digital universe would be useful for Big Data if tagged and analyzed. However, currently only 3 percent of the potentially useful data is tagged, and even less is analyzed.
- The amount of useful data is expanding with the growth of the digital universe. By 2020, 33 percent of the digital universe (13,000+ exabytes) will have Big Data value if it is tagged and analyzed.
? Much of the digital universe is unprotected: The amount of data that requires protection is growing faster than the digital universe itself.
- Less than a third of the digital universe required data protection in 2010, but that proportion is expected to exceed 40 percent by 2020.
- In 2012, while about 35 percent of the information in the digital universe required some type of data protection, less than 20 percent of the digital universe actually has these protections.
- The level of protection varies by region, with much less protection in the emerging markets.
- Challenges such as advanced threats, the security skills gap and lack of adherence to security best practices among consumers and corporations will continue to compound the issue.
? A geographic role-reversal is around the corner: Although the digital universe was a developed-world phenomenon in the early days, that is about to change as the population of the emerging markets begins to cast a longer shadow.
- While emerging markets accounted for 23 percent of the digital universe as recently as 2010, their share is already up to 36 percent in 2012.
- By 2020, IDC predicts that 62 percent of the digital universe will be attributable to emerging markets.
- The current global breakdown of the digital universe is: U.S. ? 32 percent, Western Europe ? 19 percent, China ? 13 percent, India ? 4 percent, rest of the world ? 32 percent.
- By 2020, China alone is expected to generate 22 percent of the world?s data.
? As cloud computing plays an even more important role in the management of Big Data, the number of servers worldwide is expected to grow tenfold and the amount of information managed directly by enterprise data centers will grow by a factor of 14.
? The type of data stored in the cloud will also experience a radical transformation over the next few years. By 2020, IDC predicts that 46.7 percent of data stored in the cloud will be related to entertainment ? not enterprise data. Surveillance data, embedded and medical data, and information created by computers, phones and consumer electronics will make up the remainder.
? The amount of information stored in the digital universe about individual users exceeds the amount of data that they themselves create.
? Western Europe is currently investing the most to manage the digital universe, spending $2.49 per GB. The US comes in second, investing $1.77 per GB, followed by China at $1.31 per GB and India at $0.87 per GB.
? As the infrastructure of the digital universe becomes ever more connected, information won?t reside within the region where it is consumed, nor will it need to. By 2020, IDC estimates that nearly 40 percent of data will be ?touched? by cloud computing (private and public), meaning that somewhere between a byte?s origination and consumption, it will be stored or processed in a cloud.]]>
