2021 cloud computing classification ranking

In 2021, the size of the China Cloud Computing market reached 2330.6 billion yuan. In 2015, this number was only 45 billion yuan. In the market share ranking of the global IaaS (infrastructure as service), the top ten manufacturers are Chinese companies. In the process of digital economy promoted by a new generation of information technology such as cloud computing worldwide, China is already a representative force, and cloud computing has also become an important bargaining chip for my country's scientific and technological ecology to catch up with developed countries.

Beginning with sharing

New things often appear for problems that have to be solved. Every time we browse on the Internet, each instruction can be completed in an instant, which is the result of data storage and data processing behind countless IT resources. The use of IT resources in e -commerce companies has obvious seasonality due to user access, and it will cause a large waste of IT resources in the off -season. To this end, Amazon Bezos thinks of a solution that makes IT resources flexibly, rentable and shared.

This idea was not favored by the industry at first, but Amazon took 4 years to prepare. On August 25, 2006, Amazon launched a test version of EC2 (elastic cloud computing), becoming the most important part of the Amazon Cloud Computing Service Platform AWS. It took another four years. Amazon switched his retail website to EC2 and AWS, and Internet companies such as Netflie (NET fl IX) and Pinterest also moved the services to AWS. Just nine months later, Pinterest's visits rose rapidly from 50,000 to more than 1,7 million, and the era of cloud and cloud computing officially kicked off.

Looking back at the country, Alibaba Cloud, who is also an e -commerce company, is much more difficult than Amazon. In the 1980s and 1990s of the Internet, China's network infrastructure was far from foreign countries. Domestic does not even have its own database. Internet companies can only buy expensive equipment and maintenance services abroad. With the surge in the number of users, the cost of network infrastructure alone is enough to empty the company. Under the pressure of the two mountains of cost and safety, Ma Yun decided to build his own cloud operation system.

The essence of regression calculation

Amazon's ideas have given Alibaba to inspire to build server, database, and storage systems not only meet their own computing needs, but also rent to other companies in a shared manner. Under a public "cloud", everyone only needs to focus on their own innovation and development. For example, Wang Jian, the "Father of Alibaba Cloud", said: "Yun liberated the computer's machine, so that the ability to calculate the ability to be released completely from a box and returned to the essence of calculation."

This also tells the core idea of ​​cloud computing, that is, calculation is a public service. Just like water and electricity, the faucet is unscrewed when needed. The continuous computing power will be transmitted. It only needs to be closed when not needed, which can save a lot of unnecessary expenses. For example, in order to cope with the traffic pressure of the peak order, a company needs to be equipped with a few more servers, and it needs to solve the operation and maintenance problems in the later period. When the peak values ​​have been put on hold in the past. Nowadays, as long as the cost of less than the self -built system is equipped with the "cloud" of cloud computing manufacturers, this problem can be solved.

In 2015, Alibaba held the first Yunqi Conference. Ma Yun proposed that "data will replace oil and become the core resource of the next generation." He said: "The future data is production data, and the future productivity is computing power and the innovation ability of entrepreneurs, entrepreneurial spirit, and with computing power and data, humans will change dramatically."

It can be said that, as an infrastructure, Yun, in the era of digital economy, will play an important role in promoting the high -quality development of the country's economy. Zhang Wenzhang, executive director of Amazon Cloud Technology Greater China, said in an interview that "digital transformation cannot be separated from the cloud, because cloud can bring better cost, agility and toughness, and accelerate innovation." He mentioned that it is equipped with Amazon Compared with the cost of self -built digital centers, Cloud Technology's customers have reduced an average of more than 50%on average, and the general downtime time will be reduced by 94%. For start -up companies, Shangyun is a way to quickly try and error in the lowest cost.

Integration of common needs

In the future, Yun will connect more and more companies to integrate their common needs and help them focus their energy on more important development and innovation. Therefore, cloud computing services are gradually comprehensive and refined. In terms of service forms, public clouds, private clouds, and hybrid clouds are currently recognized by the industry.

The public cloud is a computer infrastructure that suppliers can access and share for users. In the public cloud, users share the same hardware, storage and network devices with other organizations or clouds. The advantage is that they only need to pay the resources they use and do not need to be maintained. The disadvantage is that there may be security issues.

Private cloud is a dedicated cloud environment provided by an enterprise or organization. It can be located in the on -site data center or the third -party service provider. Services and infrastructure are always maintained on private networks, and hardware and software are used for organizational use. The advantage is that there is higher security, and the disadvantage is that the installation cost is high.

The hybrid cloud is a cloud computing model of one or more public clouds and private cloud environments through a safe connection combination. Data and applications can move between private cloud and public cloud. The advantage is that it provides great flexibility for the application of applications in a cloudy environment. Enterprises can configure cloud based on cost and security. The disadvantage is that it is difficult to maintain and protect because it is more complex, and compatibility may be a challenge. From the service type, it can be divided into infrastructure, such as IaaS, platform as services (PAAS), and software as SaaS. IaaS provides spaces such as server, network, storage, and data centers. PaaS provides everything required for cloud -based environmental construction and delivery of the entire life cycle of the application. SaaS provides applications running on cloud infrastructure.

The era of the cloud

my country Cloud Computing has gone through the formation period from 2006 to 2010, the development period from 2010 to 2015, and the application period from 2015 to 2020 is entering a rising maturity period. According to IDC data, the overall market size of China's public cloud services in the second half of 2021 reached $ 15.13 billion, of which the IaaS market increased by 40.1%year -on -year, and the PAAS market growth rate was 55.7%year -on -year. Internet manufacturers, telecommunications operators, IT leadership, and emerging companies are joining to promote the prosperity of this market.

IaaS is the essence of IT infrastructure. Alibaba Cloud, Tencent Cloud, Huawei Cloud and other manufacturers have developed for many years, and the scale effect has begun to appear. However, the most advantageous in this field is operators. The development momentum of Tianyi Cloud and Mobile Cloud has been very strong in recent years, but Internet manufacturers have obvious technical advantages in the development of universal PAAS/SaaS products with years of accumulation, and their potential will be huge in the future. The domestic industry is complete, and emerging companies have also gained room for survival with the technical advantages of some fields.

From the perspective of the current cloud service industry application, the pan -Internet industry is the most active. Real -time audio and video, short video, video conferences, mobile office, etc. generally use public cloud as the resource base. According to the data survey by iResearch, the pan -Internet industry Shangyun market accounts for about 27%, and the market size reaches 91 billion. Under the policy promotion, the smart government and smart cities put forward higher requirements for government governance capabilities. 56.5 billion; the financial market is also actively promoting the cloud. Due to the high demand for security compliance, it is mostly a private cloud deployment, accounting for about 11%, and the market size reaches 39.4 billion.

Under the promotion of national policies and digital economies, other industries such as industry, medical care, and education have gradually accelerated the clouds, "turning passiveness into initiative", and promoting the construction of "clouds". And as the enterprise gradually uses the cloud, cloudy will become the mainstream choice of the enterprise, and the "cloudy" solution can better adapt to the diversified needs of the enterprise's IT.

Some people predict that in the future, everything will be cloudy. As the cornerstone and hub of digital transformation, cloud computing will integrate a variety of digital technologies to empower the transformation and development of enterprises and business segments in various industries, and promote the full release of data value in the application. Wang Jian once said, "In the era of clouds, China's IT industry has the opportunity to truly change." In the era of clouds, it is also the era of accelerated development of China's economy. Chinese companies are accelerating this express train.

Conclusion

Take the wind, go through the sky, go straight down to see the mountains and rivers.
