Computing the number of cluster projects in Linux is like counting the number of startups in Silicon Valley. Unlike Windows NT, which is already hampered by its own closed environment, Linux has a large number of cluster systems to choose from, suitable for different purposes and needs. 　　But it is not easy to determine which cluster should be used. Part of the problem is that terminology clusters are used on different occasions. IT managers may be concerned with how to make the server run longer or to make the application run faster, while mathematicians may be more concerned with large numbers on the server ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

The industry has divergent views on the concept of large data. One of the most notable is the definition of the authoritative research institute Gartner: Large data is the ability to gather, manage, and process data for its users over an acceptable period of time, beyond the common hardware environment and software tools. Large data is not a simple data capacity, data speed, complexity and diversity are the key characteristics of large data. Big data often comes from new data sources, where unstructured data is the absolute mainstay. Unstructured data refers to those data that are not convenient to use in two-dimensional logical tables of the database, including all forms of office ...

Fellow leaders, distinguished guests, friends of the IT community, good morning, I am glad to have the opportunity to share with you the opportunities and challenges brought about by cloud computing to the data center, I am from the Fan Chunying of China million network. This is the traditional IDC business, always let us very tangled, how to say? We see in the operations center, see our various operators of pain, such as single point of failure, we will see network single point, server single point of failure, storage System single point, upgrade migration difficult, application deployment time is long, at the same time can not realize the application of the smooth transition, at the same time cost-effective.

"Tenkine Server channel March 21 message" With the advent of AMD's first 64-bit ARM server processor, ARM will bring a new lightweight application experience to the data center. Mobile interconnection technology, cloud computing rapid development, the load becomes more and more complex, PCs, notebooks, tablets, smartphones and other various terminals are generating a large number of different types of data every day. 　　As a result, almost all of this data has to go into the data center, which poses unprecedented challenges to the data center's responsiveness, space and energy consumption. In fact, these loads are not complicated ...

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...
