Not long ago, IDC and EMC jointly released an estimate called the "Digital Universe 2020", which estimated the development of big data within eight years from now. Here are some interesting highlights listed.
● By 2020, the digital universe will expand to 40000EB, or 40 trillion GB (that is, every man, woman and child can be spread over 5200GB by 2020). From now until 2020, the expansion of the digital universe will be about double every two years.
● By 2020, nearly 40% of the information in the digital universe may be "touched" by cloud providers - that is, one byte may be on the way from the source to the destination somewhere in the cloud The place is stored or processed. Perhaps 15% of the information will remain in the cloud.
● In the digital universe, the proportion of data that needs to be protected will be faster than the expansion of the digital universe itself, from less than one-third in 2010 to 40% in 2020.
● Today, only about half of the information that needs protection is protected. This situation may see a slight improvement by 2020, with some requiring more security to grow faster than the digital universe itself, but it still means that the amount of unprotected data will also grow at 26% .
● By 2020, about one-third of the data in the digital universe (over 13,000EB) will have big data value, but only if it is tagged and analyzed. In 2012, we think 23% of the data in the digital universe (or 643EBs) would be useful for big data if they were tagged and analyzed. However, technology always surpasses demand, and in fact, only about 3% of the data that we think may be useful are labeled and less analyzed.
