Cloud computing begins the Pandora age

In the movie "Avatar", all creatures on Pandora are connected to an organic whole through a neural network that is more complex than the human brain, forming a close and harmonious ecosystem. Jack and Nari rely on this magical collective power to defeat intruders. Do you realize that the Internet on the earth is gradually evolving into a similar organic whole, and the emergence of cloud computing is intertwined with 3G and IOT, it indicates that the process has been greatly accelerated.

As network bandwidth continues to grow, the conditions for accessing non-local computing services (including data processing, storage, and information services) over the network become more and more mature, so today we have the technology called cloud computing. It is called "Cloud" Because computing facilities are not on the local network and users do not need to care about their specific locations. So we draw a network diagram as before, it is replaced by "Alibaba Cloud. In fact, the formation of the cloud computing model has been a long history, but only when the broadband network reaches a certain level, in addition, grid computing, virtualization, SOA, fault tolerance technology, management technology, and so on mature to a certain extent and integrated together, and some large companies to promote and many successful application cases, just like a new star.

Since cloud computing service facilities are not limited by the user end, it means they can be located anywhere in the network, and their scale and capabilities are naturally limitless. All of Google's network services (including search engines and Google Earth) are built on a cloud computing platform composed of up to more than 2 million computers. Cloud computing platforms such as Amazon, Microsoft, and IBM have reached hundreds of thousands of computers and are growing rapidly. Because of the economies of scale, the use of many new technologies and methods, and the sharing and use of the public, the resource utilization rate can be greatly improved, the performance and price of cloud computing can be more than 30 times that of the traditional model, which makes cloud computing an epoch technology.

Interestingly, cloud computing and the 3G Internet of Things have almost reached the public in almost the same time period, while the three are mutually supportive and mutually beneficial. 3G brings hundreds of millions of broadband mobile users to cloud computing. These users' terminals are mobile phones, PDAs, netbooks, and laptops. They have limited computing and storage space, but have strong networking capabilities. Cloud computing has powerful computing capabilities, nearly unlimited storage space, and can support a variety of software services, providing 3G users with unprecedented service content and service experience; iot uses an astonishing number of sensors (such as hundreds of millions of RFID, Smart Dust, and video surveillance) to collect extremely large amounts of data and transmit it over the 3G broadband Internet, it brings together cloud computing facilities for processing and analysis, so as to manage and control the physical world more quickly, accurately, and intelligently, so that humans can manage production and life more precisely, achieving the "smart" status, greatly improving productivity and quality of life.

The impact of cloud computing will be profound, and it will completely change the IT industry's architecture and operation mode. The author made bold predictions here (in January 2010), asking readers to look back at the correctness of these predictions five years later (in January 2015): in the short term, the market growth of high-performance computers, high-end servers, high-end storage devices, and high-end processors will enter the inflection point, these high-end hardware markets will be squeezed out by a large number of cloud computing hardware markets with low cost, low energy consumption, and high cost effectiveness. Then, the cost is much higher than that of traditional cloud computing data centers (iDCs ), it will be quickly replaced by cloud computing data centers because of its high hardware, network, management, energy consumption costs, and low resource utilization, tens of thousands of data centers will be forced to switch to the cloud computing operation mode. Soon, the vast majority of software will be presented as a service. Data is stored in the "Cloud" When accessed by a browser. Even most games will run in the "Cloud". The user terminal is only responsible for player input and audio/video output. In the near future, there will be the phenomenon of "pan cloud computing, call Center, Network Conference Center, intelligent monitoring center, data exchange center, video monitoring center, sales management center, etc., will be increasingly concentrated to some super large professional operators to obtain a much higher cost effectiveness.

As you may see, grid computing will gradually go out of its troughs and cloud computing experts after experiencing the hardships of the Internet bubble, achieving interoperability and resource sharing between cloud computing platforms of different vendors, the combination of tightly coupled high-performance scientific computing and loosely coupled high-throughput commercial computing enables the main computing facilities on the Internet to be integrated into an organic whole, grid + cloud ).

In the future, Iot will turn hundreds of millions of objects and small environments into perception and control objects for cloud computing. 3g and 4G will turn everyone into an application node and smart node in cloud computing, the highly integrated cloud computing and grid computing Consortium (that is, the cloud grid) is like the goddess of Pandora. It will combine the power of this planet with its powerful capabilities and wisdom ......
