According to the "Wall Street Journal" website, in 2017, the three largest US companies providing cloud services - Amazon, Microsoft and Google invested a total of 41.6 billion US dollars in capital expenditures and capital leases (capital leases), an increase of 33% over 2016. 23% increase in expenditure in 2016. Not all of these funds are used for data center construction, but all three companies regard the expansion of cloud networks as a key investment. The world's leading technology companies are further leveraging their strengths to continuously expand the global coverage of cloud network services and provide online services to more enterprises and individual users. This requires a large investment, and the demand for advanced technologies such as improving computing performance has increased expenditures year by year. In addition, there are indications that these companies are unlikely to slow down investment this year. As can be seen from the figure below, the capital expenditures of several major cloud service companies are increasing year by year. How much money does the cloud computing market burn? In 2017, 19 cloud manufacturers smashed $63.8 billion Capital expenditures of other companies follow a similar trajectory. In 2017, RBC Capital Markets added 19 cloud service providers to invest a total of 63.8 billion US dollars, an increase of 22% over last year. RBC analyst Amit Daryanani predicted this year This value will increase by 27% to $81 billion. Analysts at KeyBanc Capital Markets also forecast a 27% increase in cloud spending this year. Demand for cloud computing services is still hot, showing no signs of a slowdown in development. Last year, Amazon's AWS cloud business revenue climbed 43% to $17.5 billion. JPMorgan estimates that Microsoft's Aoqing cloud business revenue has almost doubled to about $5.3 billion. According to Alphabet, Google Cloud's revenue per quarter is about $1 billion, but did not disclose relevant detailed data. These are good news for upstream providers of cloud services. Some of NVIDIA's chips can be used to enhance the AI ​​performance of cloud networks. The company's data center business has achieved triple-digit growth for seven consecutive quarters. Intel’s earnings report last month showed that data center business revenues rose 20% in the fourth quarter, which really surprised investors. Arista Networks sells private network equipment to large cloud providers. Some analysts predict that their fourth-quarter revenue is expected to climb 41%. The business opportunities are so huge, and the large amount of investment is reasonable. Cloud service spending still occupies a relatively small proportion of total IT spending. Analysts at Keban Capital Markets predict that by 2022, the total revenue of the cloud business will reach 314 billion US dollars, which is three times the current. For companies that have already taken the lead in this competition, it is no good to step on the brakes now.
