Big data is hot now, enterprises, individuals are talking about big data have their own different views and views, but the author through the day-to-day chat with friends, found that many friends still have some misconceptions about large data, such as many people will think Big data is a latest technology, Some friends think that there are more data to serve only one person and so on, these questions we will discuss with you in this issue. Big data is not a new technology big data is now integrated into our lives, people in the day-to-day work of the office will be exposed to large data, the large number of data are always different ...

The cloud economy is so compelling, today, more and more data center managers are starting to assess which additional applications are more valuable to cloud services, whether it is a private cloud that deploys its own enterprise, or whether it is a mix or a public cloud service that uses Amazon Network services or other service providers. At the same time, there is growing evidence that proven enterprise-class features are being looked at, as they provide reliable services to comply with SLA agreements. As data center managers become accustomed to using cloud services more and more, they don't want to give up ...

Before yarn, Hadoop was only available for offline processing scenarios. Based on real-time demand, organizations have developed their own streaming framework, this time we are talking about two sql-on-hadoop projects, as well as two well-known Hadoop solution Providers--impala vs. Stinger. Singer:stinger first appeared in Hive 0.11 (HDP 1.3), with a total of 3 phase goals, of which phase I and II had been delivered. Through the hortonwo ...

The Open-source implementation of Hadoop, Google's 3 papers, allows developers to do massive data processing on commercial servers, which, while not suitable for real-time scenarios, allows users to do off-line data analysis at a lower cost, which is why when the dirty-handling framework is lined up, Hadoop is still widely used and the reason for discussion.   This issue starts with Hadoop and opens the door to business based data analysis. The first to share was the architect, Zhou, from the nine city technical department, who was in charge of Hadoop. He is also me ...

Cloud computing can be divided into public cloud by type, private cloud and mixed cloud three kinds, now many enterprises are subordinate in the company's private cloud, the public cloud also only wants IBM, Amazon and Microsoft industry big manufacturers can have the strength to provide. Talk about the word personal cloud, perhaps many people are not very familiar with, perhaps many people will think that the personal cloud is what we usually call private cloud, is not. A cloud with a market value of 4 billion dollars talking about personal cloud service The personal cloud we're talking about here refers to the use of smartphones, tablets, TVs, and PCs, seamless through the internet ...

Legal risk in cloud computing environment--from the perspective of data security Xu Huili Cloud computing technology in providing people with economic, convenient service experience, but also buried a lot of legal hidden dangers. Now the economic advantage of this new technology has gone beyond people's concerns about security, and cloud services are pervasive in everyday life. Only by keeping a clear understanding of the potential legal risks that they face can the technology better benefit people's lives and reduce the negative effects of risk. Data security is one of the most urgent core issues in this field, which endangers the user's right of privacy, trade secret, copyright and other legal rights.
