At present, public cloud service enterprises have reached the international advanced level in technology. The public cloud service platforms of Internet backbone enterprises such as Baidu, Alibaba and Tencent have 1000pb data processing capacity

frequent innovation of public cloud technology

through a large amount of investment and active research and development in the field of cloud computing, China's public cloud service enterprises have reached the international advanced level in technology. According to Chen Guang, a researcher at the Institute of software and information services of CCID think tank, at present, Alibaba cloud, Baidu, Tencent and other domestic public cloud service enterprises have made breakthroughs in key technology areas such as multi tenant resource sharing, cross platform data center management, large-scale storage without complex steps and requirements, and virtual elastic computing, It has greatly improved the ability to control domestic information and data resources and the ability to provide safe and reliable public cloud services

according to the statistics of professional institutions, the scale of China's public cloud market reached about 3.5 billion yuan in 2012 and 4.76 billion yuan in 2013, with a growth rate of 36%, much higher than the 25% growth rate of the international market in the same period; The scale of the proprietary cloud market is about 60billion to 70billion yuan, mainly concentrated in large enterprises in telecommunications, energy, power, medicine and other industries and e-government systems in some developed regions

in the public cloud market, China's key technology innovation highlights frequently. The data processing capacity of Baidu cloud platform has reached 1000pb

1000pb? Figuratively speaking, the amount of data stored in 1PB is about the same as that of 400 billion pages of printed text; So far, the data volume of all printing materials produced by human beings is only equivalent to 200pb. It takes 223000 DVDs to save 1PB of data. Chen Guang explained

Ali is not willing to fall behind. In October, 2013, Alibaba cloud's independently developed Feitian 5K plan was completed. The scale of single cluster servers reached 5000, and the 100TB sorting experiment could not be completed in 30 minutes, far exceeding the 71 minute world record set by yah OO since the "tianniu incident" in July of the same year, and reaching the international advanced level in terms of processing capacity and speed

cloud computing has formed three camps

around 2010, China's cloud computing has formed a complete industrial chain from application software, operating system to hardware, and began to get large-scale commercial applications

cloud computing operators take computer capabilities as a resource, gather them together, and then distribute them to customers in need through the network. Customers need more computing resources, and service providers give more; As soon as customer demand falls, distribution can be immediately reduced. After customers purchase this service, they no longer need to purchase additional software and hardware. For small companies, this means that they don't need to invest a lot of money to buy servers and software. They can enjoy the software and hardware capabilities that only large companies can configure before by renting

a personage in the industry vividly introduced that, just like water supply and power transmission, cloud computing has turned computing from tangible products into intangible services. Computing power has become a transportable service, which is the most important innovation and change in the field of information technology after the emergence of the Internet

at present, China's cloud computing industry has initially formed three mainstream competitive camps, namely, the Internet camp, the IT camp and the telecom operator camp. In terms of the Internet camp, Baidu, Alibaba, Tencent, etc. are mainly oriented to the public cloud market, providing public cloud services for small and medium-sized enterprises and independent developers. In terms of it camp, Huawei, Inspur, dawning, etc. mainly provide proprietary cloud products and solutions for enterprise level customers. They mainly focus on mainstream it, software, network equipment and system service providers, enter the enterprise level market through large-scale mergers and acquisitions and extensive cooperation, and extend to government cloud, industry cloud and other fields. In terms of telecom operators' camp, China Mobile [-1.05%] and Chinatelecom [-1.14%] have entered the public cloud and private cloud markets at the same time to provide services to governments, enterprises and industrial users

at the same time, China's cloud computing enterprises are constantly innovating service modes in the exploration of changing traditional service modes. Location based services, payment services, transportation services and other cloud services related to people's life, work and entertainment have emerged in large numbers. With the continuous innovation of cloud computing products and services, the number of enterprises and individual users has achieved rapid growth. Baidu, Tencent, Qihoo and other enterprises have more than 100million users of cloud service platforms, and Alibaba and Kingdee cloud services support more than 700000 small and medium-sized enterprises

problems to be solved

it is worth noting that although the development is fast, there are still some problems in China's cloud computing industry, which need to be solved as soon as possible in the growth process

first of all, cloud computing consumes a huge amount of energy, and there is an urgent need for green energy-saving technology. Globally, the total power consumption of ICT accounts for about 8% of the total global power consumption. Some professionals have analyzed that the data center of China Unicom [-2.58% capital research report] consumes 9.9 billion kwh of electricity every year and needs 920000 tons of standard coal to meet its energy consumption needs; The annual power consumption of Chinatelecom data center is 11.2 billion kwh, with a total annual consumption of 1029500 tons of standard coal. By 2020, the power demand of cloud computing industry will increase by more than 60%

secondly, the profitability of cloud computing enterprises is generally not strong. In 2013, the scale of China's public cloud market was less than 5billion, and the profit model of cloud computing needs further exploration. For example, many cloud service enterprises have launched cloud storage services, but most cloud storage services for individuals are free, and cloud enterprises need to pay a lot of money in advance to attract users and traffic. In addition, the market of small and medium-sized enterprises still needs to be further developed. At present, the proportion of small and medium-sized enterprises in China using cloud services is only about 10%, and the number of enterprises that have the courage to try is still relatively small

finally, the phenomenon of light service in reconstruction is still serious. At present, the development of cloud computing in various parts of China is mainly based on the construction of infrastructure such as data centers, which has hidden overcapacity, repeated construction and other phenomena. Therefore, relevant experts call for the construction of cloud computing infrastructure to match the ability and demand of cloud services and Cloud Applications to avoid disorderly development and blind construction

what is cloud computing

cloud computing can be defined from the perspective of computing mode, service mode, etc. From the perspective of computing mode, cloud computing is to distribute computing tasks on a large number of interconnected and uniformly managed computers, and use hardware, software, networks and other IT resources to complete the required computing tasks. From the perspective of service mode, cloud computing is that service providers use their own hardware equipment, software, networks and other resources to meet the needs of users to use software and hardware equipment or obtain information by means of resource leasing

in the cloud computing mode, users can use cloud computing services through the network without purchasing and configuring a large number of IT resources. Therefore, cloud computing is usually compared to a tap water supply system. People don't need to dig wells separately. As long as they turn on the tap at home (similar to the client), the incoming water (similar to the information technology capability) can flow out of the water plant (similar to the cloud) through the water transmission pipeline (similar to the network)
