Making bricks to gossip about big data--how big is the amount of data in China?

This is a problem that is destined to be made into bricks, but it may be quite clear that this is a pat on the back. So anyway, let's throw a brick.

We're all talking about the advent of the big data age, the big Bang of information and data. From the beginning of the 2013, for large data outbreaks of anxiety, a sense of urgency, involuntarily involved in even the feeling of powerlessness, drive a large number of industries, enterprises and groups to pay attention to and start contact and understanding of large data, consciously or unconsciously, actively or reluctantly into the wave of the tide. But really when it comes to big data, how much data do we have around us, what industries are they in, what data is available, what industries are already using data to get into the industry's internet and data-led transformations?

May see the Territory is still vague. Therefore, we embrace very good hope to the first to eat crabs and look forward to from the industry's corrective and brick attitude, first of all to try to the domestic areas, industry and institutions of data ownership, use and future path to do a rough investigation, carding and judgment, For the large data era of China's various fields of data assets ownership and use, that is, our data assets to do a stock count, but also to various industries, systems into large data, and embrace the progress of the Internet industry and the future to make a simple judgment. In fact, the big data problem is undoubtedly the stars, but only in a relatively complete view of the stars, if the dust, we can be a glimpse of the secret.

Gossip less, and now start reckoning.

From the data we have in hand, 2013, China's storage market shipments of more than 1 EB, storage Total and IDC has released forecasts that in the next 3-4 years, China's total storage capacity may reach 18 EB. From the demand of data storage market, the Internet, medical health, communication, The demand of public safety and military industry is the main, and the rising trend is obvious.

Given the close correlation between storage and servers, we can tell from the information we have obtained that the total number of servers running in the world is over 50 million, and the total capacity of servers running in the United States is nearly 10 million. According to the public data of various markets, the total number of domestic server sales in China in 2013 is close to 1 million units. Overall, as of the end of 2013, the total number of servers running in mainland China was more than 3 million.

From the existing storage capacity, China currently can store data capacity around 8eb-10eb, the existing can be saved data capacity of about 5EB, and every two years or so will be doubled. The overall distribution of these stored data is: 1/3 of the current capacity of the media/Internet, Government sector/telecommunications enterprises accounted for 1/3, other financial, educational, manufacturing, service sectors accounted for the remaining 1/3 of the amount of data.

Public data show that the internet search giant Baidu 2013 with data volumes close to EB level, Ali, Tencent stated that the total amount of data they stored has reached more than PB. In addition, telecommunications, health care, finance, public security, transportation, meteorology and other aspects of the amount of data saved to dozens of or hundreds of PB level.

The "2020 Digital Universe" report, currently widely cited by IDC and EMC, predicts that by 2020, the global digital universe will swell to 40000EB, and that it will be effectively stored and applied, and it is hard to imagine how this amount is going to be used efficiently. However, we see the report that, from now until 2020, the expansion rate of the global digital universe is about doubling every two years. In fact, based on the above findings and the server capacity survey, we can also make a relatively reasonable inference: at present, only about 1% of the data produced in the world can be saved, that is, today the world can be preserved data is about 50EB, The data that is marked and used for analysis is less than 10%.

As the world's largest population and computing equipment holdings, the amount of data that our country can produce every year is also extremely huge, have the data to say that 2014 years may even reach the ZB level, but the data that is really effectively stored is only a very small part of it, the proportion that China holds the data to occupy the global data is about about 10%, That's the 5EB. The data, which is currently labeled and used for analysis, is only about 500PB, and is close to 10% per cent.

Along with the rapid popularization of cloud computing and industry, enterprises and departments for the preservation of data assets and use of awareness, as well as through the Internet, large data on the industry to change the will, the next 2-3 years will be more and more industries, large enterprises into the PB, petabytes, even EB level data club, In the next 3-3 years, China's total data will be doubled up, we predict 2015 China will likely break through 10EB data Holdings, tagged and analyzed using data will also rise to the EB level, these data growth in the Internet, government affairs, health care, education, security and other industries and areas to contribute the most, The relative traditional logistics, manufacturing, and even agriculture and other fields of data ownership growth will be more obvious.
