2013 is called the first year of big data, and all walks of life are gradually opening the era of big data application. Until now, big data is still talked about by people. What is big data? Is 1PB big enough? If you don't have an intuitive impression, you can think of the hard disk capacity of your computer. The standard configuration is 500G-1TB. Most people use it for a year or two, and this part of the capacity may not be used up. And 1PB=1024TB=1048576GB. In practice, the data volume of a small well-known game is about tens of terabytes a day, or even more. If you thought the PB unit was already the largest? That phone number list would be a big mistake! ! ! ! On top of PB, there are EB (Exabyte), ZB (Zettabyte), YB (Yottabyte), and these The unit is only the current unit given by the convenient statistics of massive data, and larger units may appear in the future. According to Intel CEO Brian Krzanich, Internet users will generate 1.5GB of data per day in 2020. HIS data predicts that by 2025, the total installed base of Internet (IoT)-connected devices worldwide is expected to reach 75.44 billion, and the amount of data generated by these devices every day can be imagined. According to the previous data relationship, it is concluded that 1ZB is about 1.1 trillion GB, which is equivalent to the total amount of sand in the world. It is not difficult to see from the above graph that internet data is exploding every year. Of course, big data is not just a large amount of data, it has other deeper meanings. For big data, the McKinsey Global Institute defines it as: "A collection of data that is so large that its acquisition, storage, management, and analysis are far beyond the capabilities of traditional database software tools."
