Open World Computing

I have experienced the myth world from microcomputers to supercomputers, from email to Internet, and from parallel computing (parallel comouting), to decentralized computing (decentralized computing), To the application of distributed Computing (distributed computing), by Telnet remote in the large computer with more than 3,000 CPUs (such as Japan's so-called fifth generation of computers) on the use of 1024 CPUs to verify their own ...

A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...

In the absence of a breakthrough in desktop Linux, the steady growth of Linux in the server market has made it more of an enterprise-class application business card. However, with Linux's breakthrough in the field of mobile computing, mobile office has a new interpretation of the concept of Linux enterprise-class applications.　　In addition, the development of WEB 2.0 and cloud computing has brought new development opportunities and challenges to open source. The virtualization giant VMware, a firm leader in Mobile, has recently joined the Open-source organization Li ...

As a new computing model, cloud computing is still in its early stage of development. Many different sizes and types of providers provide their own cloud-based application services. This paper introduces three typical cloud computing implementations, such as Amazon, Google and IBM, to analyze the specific technology behind "cloud computing", to analyze the current cloud computing platform construction method and the application construction way. Chen Zheng People's Republic of Tsinghua University 1:google cloud computing platform and application Google's cloud computing technology is actually for go ...

This paper analyzes the depth of cloud computing, cloud computing, cloud computing and cloud computing. 　　Interpretation of cloud computing. Cloud computing deep understanding of what is "cloud computing" in the end? In the past two years, the manufacturers of various companies stand in their respective positions to interpret, make a different opinion. 　　New new technology is a daunting term, there is no unified definition of things, more and more confusing, confusing mind. "Brother Smoke is not smoke, is lonely" ——...

"China Cloud Network News" May 29, to vigorously develop and promote the Beijing Science and technology original ability for the purpose of "2013 Beijing (International) Open Source Conference" in Beijing New Century hotel Nikko grand opening. The conference by the Beijing Municipal Commission guidance, China Software Industry Association, hosted by the Cloud Network, and has been China Cloud Industry Alliance, Zhongguancun Cloud Computing Industry Alliance, the trend of the sky Cloud and other units of strong support. The conference takes "open source China original Beijing" as the theme, through the rich forward-looking thought feast, strives for Beijing to occupy under the World Science and technology development new trend.

As the focus of IT industry, cloud computing in the domestic popular for many years, the early stage of vigorous, almost to the point of the word will be called cloud. In the past two years, with the return of rational consciousness, cloud computing discussion craze gradually cooling, more and more cloud computing products and solutions began to surface, cloud computing is moving towards a pragmatic and landing application period. At any stage, security is always accompanied by the ebb and flow of cloud computing, the hardware and software manufacturers, telecom operators and other industry parties can not avoid the key issues. "Many people are accustomed to comparing cloud computing to tap water, where users can get and ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

Cloud computing initial fixed investment high, marginal input low, which leads to diminishing marginal cost, marginal income increment. In cloud computing, both infrastructure, platform and software require higher initial fixed inputs. Once built, however, it can be reused over and over again, and each value-added business, with a lower marginal input, can be launched without developing infrastructure, platforms and software from scratch. What is cloud computing? Now is not without answers, but too many answers. Now the answer to "What is cloud computing" is so much that people can't figure out what cloud computing is. ...

When looking for open source cloud computing service providers, companies with strong development capabilities or specific business applications tend to routinely avoid commercial cloud computing service providers. 　　Open source cloud computing platforms such as Eucalyptus, OpenStack and abiquo are expected to succeed in building private cloud computing opportunities for companies. But some problems remain, such as how the Open-source cloud services provider can reflect its value. Who will pull the top? Can the Eucalyptus system win in the brutal competition with OpenStack? Op ...
