HBase terms in this article: column-oriented: Row column Group: Column families Column: Column unit: Cell Understanding HBase (an Open-source Google bigtable practical application) The biggest difficulty is what is HBase's data structure concept? First HBase is different from the general relational database, which is a database suitable for unstructured data storage. Another difference is that HBase is based on columns rather than on rows. Goo ...

This article describes ways to perform large data analysis using the R language and similar tools, and to extend large data services in the cloud. In this paper, a kind of digital photo management which is a simple and large data service is analyzed in detail, and the key elements of searching, analyzing and machine learning are applied to the unstructured data. This article focuses on applications that use large data, explains the basic concepts behind large data analysis, and how to combine these concepts with business intelligence (BI) applications and parallel technologies, such as the computer Vision (CV) and ... as described in part 3rd of the Cloud Extensions series.

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

With Intel's drive, IT system communications bandwidth and computing power follow Molfa to record highs, maintaining a doubling of growth rates every 12-18 months. At the same time, IDC's latest "Digital Universe" study predicts that data will grow faster than Moore's law, reaching 1.8ZB in 2011, and that the company will manage 50 times times the current amount of data over the next 10 years, and file volumes will increase 75 times times. 　　Under the background of the rapid expansion of the digital universe, the concept of "big data" came into being. Detailed explanation big ...

Breakthroughs in device technology are used to transform between "compute-centric" and more balanced "data-centric" computing infrastructures. The author investigates storage-level memory, demonstrates how to populate the long-standing performance gap between RAM and rotating disk storage, and details the use of I/O bus coprocessor (which handles similar data), and explains how to build a low-cost high-performance interconnect network using InfiniBand, The extensible storage of unstructured data is discussed. Computational systems engineering has historically been made up of extended processors and dynamic RAM ...

OpenStack Object Storage (Swift) is one of the subprojects of the OpenStack Open source Cloud project, known as Object storage, which provides powerful extensibility, redundancy, and durability. This article will describe swift in terms of architecture, principles, and practices. Swift is not a file system or a real-time data storage system, which is called object storage and is used for long-term storage of permanent types of static data that can be retrieved, adjusted, and updated as necessary. Examples of data types that are best suited for storage are virtual machine mirroring, picture saving ...

Search giant Google, with its cloud computing technology, is at the forefront of a large data center architecture configuration. The Sun's chief technology officer, Greg Papadopoulos, used cloud computing as a spectral phenomenon called redshift (red Shift), and Sun is the only vendor in the market that offers a system architecture solution based on cloud computing ideas. Astronomers often use the Doppler effect (Doppler multiplying) or redshift to define the expansion of the universe. ...

Familiar with the friendship between the two kingdoms should not be unfamiliar with Zhuge Liang and Yi both die on the use of this meter has a wonderful play, each has won, No. But the real play is still the ultimate in the Three Kingdoms of the Wei (Jin) name Deng Ai. Deng Ai is a military genius, a surprise attack on Chengdu, (a bit of World War II Japan's mountain Ben 56 surprise Pearl Harbor taste, when ...)

DAS, Nas, and San three storage for storage, many people still stay on the simple hard disk, memory, with the rapid development of the network era, storage technology constantly updated, storage has long been in the hard disk technology based on the rapid development. 　　Now that enterprise-class storage technology is constantly pouring into the marketplace, making it difficult for users to perceive professional terminology, such as networked storage, virtual storage, cloud storage, data deduplication, archiving technology, and so on, are these technologies confusing? Although mastering these terms doesn't seem practical to most people ...
