Using Hadoop to drive large-scale data analysis does not necessarily mean that building a good, old array of distributed storage can be a better choice. Hadoop's original architecture was designed to use a relatively inexpensive commodity server and its local storage in a scale-out manner. Hadoop's original goal was to cost-effectively develop and utilize data, which in the past did not work. We've all heard of words like large-scale data, large-scale data types, large-scale data speeds, etc. that describe these previously unmanageable data sets. Given the definition so ...

1. The introduction of large data production makes data analysis and application more complex, difficult to manage. According to statistics, the amount of data produced in the world over the past 3 years is more than the previous 400 years, including documents, pictures, videos, web pages, e-mail, microblogging and other types, of which only 20% are structured data, 80% is unstructured data. The increase of data makes the data security and privacy protection problem become more and more prominent, all kinds of security incidents to the enterprise and user wake-up alarm. Throughout the data lifecycle, businesses need to comply with stricter security standards and confidentiality rules ...

But if this is the equivalent of cloud computing and power, and even the idea that data is tied to power, and that people are still weak in the sense of the outside cloud, it is too absolute to let them know that data is not electricity. There are many differences between them, the fundamental difference is: for electricity ...
