According to iiMedia Research, the global cloud computing market in 2018 reached US$305.8 billion, up 17.52% year-on-year. Among them, the size of the public cloud market grew to US$139.2 billion, up 25.41% year-on-year. It is estimated that the global public cloud market will reach US$171 billion in 2019. Compared with the global market, China's cloud computing market is still small, and the overall development speed of the industry remains at a relatively high level. As the second echelon enterprise of China's cloud service providers, UCloud enjoys the dividends brought by the rapid growth of the industry. Its business income in 2018 reached 118,743.32 million yuan, an increase of 41.39%, gross profit of 46,878.79 million yuan, an increase of 53.08%. Although UCloud has achieved profitability, the problem of excessive dependence on public cloud business is still prominent. With the increasing competition in the public cloud market, the company has to confront the low-price competition strategy of the head manufacturer, and the uncertainty of profitability has increased. iiMedia Consulting Analysts believe that there is a certain gap between the top manufacturers and the top manufacturers, and there are still many challenges in the development. However, the third-party neutrality and strong customized service capabilities can not be ignored in the field of vertical segmentation.
