云计算发展的三个时代分别是(云计算发展状态是什么)

A report released by IDC shows that in the four years from the end of 2009 to the end of 2013, cloud computing will bring $800 billion to the world new business income, bringing more than 1.105 billion yuan in new business income to China. At the same time, the Oriental Strategy Team predicts that by 2015, the scale of my country's cloud computing industry chain will reach 750 billion to 1 trillion yuan, and its share in strategic emerging industries is expected to reach 15 %above. Based on this, the "Guiding Opinions on Accelerating the Development of High-tech Service Industry" jointly participated by the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Science and Technology and other ministries and commissions has entered the drafting stage, in which the cloud computing industry will be clearly defined Be the protagonist of the future high-tech service industry. In the next period of time, with the successive introduction of a number of supporting policies, cloud computing's market space of nearly one trillion yuan will gradually open up, and cloud computing will also become a concern of the IT industry and even society in the 21st century. focus and hot spots.

Compared to the United States, China’s cloud computing started late and is currently in a stage of rapid growth. The global cloud computing market is rising steadily, and the public cloud market reached US$188.3 billion in 2019. In 2019, my country's cloud computing market reached 133.4 billion yuan, of which the public cloud market was 68.93 billion yuan and the private cloud market was 64.52 billion yuan. The public cloud market exceeded the private cloud for the first time. Judging from the proportion of global and Chinese cloud computing markets in IT expenditures, China's proportion is lower than the global level.

It started late and has developed rapidly in recent years

Compared to the United States, China’s cloud computing started late and is currently in a stage of rapid growth. The United States had proposed the concept of cloud computing as early as 2005. In the following three years, driven by technology, the application field gradually became popular. China developed five years later than the United States. After 2007, China began to develop cloud computing with the United States as its teacher. After 2009, policies continued to be highly supportive, making cloud computing widely used.

Since 2007, the development of cloud computing in China has gone through four stages: the first stage is the market introduction stage, the concept of cloud computing has just appeared in China, and customers have low awareness of cloud computing; The second stage is the growth stage. Users have a relatively good understanding of cloud computing, and more and more manufacturers have begun to enter the industry; the third stage is the maturity stage. At this time, the competition pattern of cloud computing manufacturers has basically formed, and manufacturers have begun to move from a more mature stage. Starting with mature and excellent solutions, the application of the SaaS model has gradually become mainstream; the fourth stage is the rapid growth stage. At this stage, the overall scale of my country's cloud computing market is relatively small, lagging behind the global cloud computing market by 3 to 5 years, and from segmentation From a field perspective, the domestic SaaS market still lacks industry leaders.

Global cloud computing has developed steadily, with the public cloud market reaching US$188.3 billion

In recent years, the global cloud computing market has shown a steady upward trend. In 2019, the global public cloud market represented by IaaS, PaaS and SaaS reached US$188.3 billion, with a growth rate of 20.86%. Stimulated by policy promotion and market demand, analysts believe that the strong development momentum of the cloud market is expected to be maintained in the next few years, with an average growth rate of approximately 18%, and the global cloud computing market size will reach approximately US$225.3 billion in 2020.

Note: According to Gartner statistics, cloud computing here is a public cloud service market.

The market size has increased rapidly, and public cloud has surpassed private cloud for the first time

In my country, the cloud computing market has grown from the initial billions to the current scale of hundreds of billions, and the industry has developed rapidly. According to data disclosed by the China Academy of Information and Communications Technology, from 2017 to 2019, the market size of my country's cloud computing industry grew at a rate of more than 30%, showing a rapid growth trend. In 2019, my country's cloud computing market reached 133.4 billion yuan, a year-on-year increase of 38.6%. In the future, benefiting from the advancement of new infrastructure, the cloud computing industry will still usher in a golden development period.

Note: The market size here is the total of public cloud and private cloud markets.

From the perspective of market segments, from 2016 to 2019, the public cloud market share increased year by year, reaching 51.65% in 2019; the private cloud market share decreased year by year, reaching 48.35% in 2019. In 2019, my country's public cloud market reached 68.93 billion yuan, and the private cloud market reached 64.52 billion yuan. The public cloud market exceeded private cloud for the first time.

The proportion of cloud computing in IT expenditures is lower than that of the world, and there is broad room for future development

According to Gartner, the world's leading information technology research and consulting company, in 2020 The total global IT spending is expected to reach 3.4 trillion US dollars; the total IT spending in China is expected to reach 2.77 trillion yuan. Judging from the proportion of global and Chinese cloud computing markets in IT expenditures, China's proportion is lower than the global level. China's cloud computing market still has a lot of room for catching up in the future.

Note: Cloud computing here refers to the public cloud service market.
