Today, in Chengdu, diners can trace the source of every piece of pork eaten in the "City Cloud", and in Jiangxi, about 500 pilot hospitals have been using cloud services at the Wuxi Cloud Computing Center to maintain patient information. 　　This is based on the "City Cloud" on the basis of the city of Cloud in the next three years or will be more than 10, and form a network, become a foundation, there are applications, efficient Chinese Xiangyun. "From cloud computing you can see the emancipation of the mind of a city. "For those who do not know the Chengdu Cloud Computing Center and the Wuxi Cloud Computing Center, ...

Why "cloud"? "Everything is about demand and using existing processing power and resources." "In 1965, Moore's Law, published by Intel co-founder Moore Gordon E. Moore, predicts that the number of transistors used in the processor will double every two years." 　　The past 40 years have proved the correctness of this law, and the law is likely to remain true at least 2020 years ago. If you compare today's typical handheld devices ...

"The cloud is about all the need for and use of existing processing capabilities and resources." "In 1965, Moore's Law, published by Intel co-founder Moore Gordon E. Moore, predicts that the number of transistors used in the processor will double every two years." The past 40 years have proved the correctness of this law, and the law is likely to remain valid at least 2020 years ago. If you compare today's typical handheld devices (such as iPad2), its A9 dual-core processor is already an Intel Pentium III processor operation ...

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 ...

Revenues of around $1 billion a year dominate the cloud computing market. All this has made Amazon a target for companies with plans to provide cloud services, whether in the US or elsewhere in the world, including some it giants: IBM, Microsoft, Google, Rackspace, and so on. And the domestic hope to emulate Amazon, in the cloud services market Siege of the company also a few, Aliyun, Sheng, million network, Century interconnection. But what kind of strength is needed to challenge Amazon? Industry has experts to give such a view, competing with Amazon AWS, you need three ...

Tower server should be the most people see, but also the most easy to understand a type of server structure, because its shape and structure are similar to our normal use of the vertical PC, of course, because the server's motherboard expansion is strong, the slot is also a heap, so the size of the larger than the ordinary motherboard, 　　As a result, the tower server's mainframe chassis is also larger than the standard ATX chassis, typically reserving enough internal space for future hardware and power redundancy expansion. Because the tower server chassis is relatively large, the server configuration can be very high, redundant expansion can be very complete, so it should ...
