Cloud computing is a new IT resource delivery model that can be simply understood as a data center where computers can automatically manage and dynamically allocate, deploy, configure, reconfigure, and recycle resources, and automatically install software and applications. Cloud computing consists of hardware, software, and services. Hardware is primarily a x86 or power machine. Software includes the management of computer automation software, as well as the management of software. Service refers to the building of Cloud computing center and its future operation. The Cloud Computing Center provides its users with a virtual computer that is loaded with software and applications.

What about cloud computing performance? It depends on who you ask. There are three cloud computing models, and which one you use determines what performance you will get. People who use software as a service (SaaS) system and process standard Web latency cannot tell you too much about performance. 　　However, those who use the advanced "large data" system will tell you something very different. You need to consider several performance patterns, the performance pattern can be divided into three non ...

Over the past one or two years, SaaS (software as a service), PaaS (Platform-service), cloud computing, these three concepts have been hot-fried in the software world. At first glance, there are many similarities between the three, such as the use of the Internet to provide related services or applications, are based on the rental model, and also pay on demand. But under the surface of prosperity, from a technical point of view, what are the differences between these concepts? Which vendors are providing relevant technology? What are the specific products? Many users of this is foggy, the choice can not be. We interviewed the industry ...

If you ask 6 people about how to define cloud computing, you may get at least a dozen numbers of answers. And if you ask them what the relationship between software, SaaS, and cloud computing is, you may get a much more varied answer. Currently, companies that use software as a service have access to applications based on an ordered price model, which is also commonly known as on-demand software. This application is typically deployed outside the company (contrary to the software installed in-house). The result is a reduction in the cost of getting software and hardware, and ...

The rise of cloud computing is undoubtedly one of the most exciting events in the history of the Internet. So, cloud computing in the Internet and information society in the course of the development of what position?    Looking back on the history of Internet development and looking forward to the future of Internet, we can divide into the following stages: 1.

Cloud computing is known as "cloud", probably because one of the originator of cloud computing, Amazon, has taken a new name, "Elastic Computing Cloud" (EC2), and achieved commercial success. At that time, the grid has gone through the course of 10 years, we have an aesthetic fatigue, the new name is refreshing, and thus quickly accepted. In fact, from 2003 onwards, IBM, SUN, HP and so on have been offered like buying electricity to buy water through a network to buy computing power and storage space services [1][2], but at that time the charge is more expensive: ...
