Recently, Huawei and tpcast jointly completed the instry's first cloud VR service verification under 5g experimental network, realizing real-time cloud rendering of interactive CG (computer graphics) VR content, which is a revolutionary progress in the history of VR instry

from last year to this year, Huawei cloud seems to have sprung up. We can always see Huawei cloud's achievements in the media

according to the data on Huawei's official cloud website, Huawei released its cloud strategy in 2010, and then officially released its cloud operating system fusionsphere after three years, and there has been no substantial progress in the next four years. It was not until Xu Zhijun, vice chairman and CEO of Huawei, announced the establishment of cloud Bu ring the Huawei China ecological partnership conference in March 2017 that Huawei began to make full use of cloud computing and achieved rapid development

it can be said that Huawei cloud really started in 2017, which is quite late in the highly competitive cloud computing market, but the rapid progress of Huawei cloud is obvious to all, isn't it surprising for many people

coincides with the critical period of instry upgrading

public cloud has been developing for ten years in the world, and the first batch of customers are mainly Internet enterprises. In this generation of public cloud, Amazon, Microsoft and Alibaba have obvious advantages. But at present, two changes have taken place in the market: first, more customers of traditional enterprises or government agencies begin to migrate to the cloud, transforming the traditional architecture with cloud computing, big data and artificial intelligence technologies, and enjoying the dividends of these new technologies. Second, the last generation of public cloud has been developing for ten years, and the technology and architecture are facing upgrading. Especially with the help of a new round of artificial intelligence tide, it is the general trend for enterprises to go to the cloud, and creating cloud ecology has become the top-level construction goal of the cloud instry

as we all know, the data on the public cloud is the most sensitive topic in the whole instry. Huawei has been emphasizing "don't touch data" since its first day. Under the guidance of this strategic idea, Huawei has won the trust of a large number of partners in a short time. By the end of 2017, Huawei cloud had nearly 2000 ecological partners. With the help of so many partners, it is impossible for Huawei cloud to be strong

"action group" corporate culture

people who know Huawei all know that this company is a typical "action group": if you don't do what you want to do, you have to do it, do it with all your strength, do the best, and do it to an incomparable degree. This is true of Huawei's enterprise business and Huawei's consumer business, which have continued to rise in recent years. Now it's Huawei's turn to cloud business

in any instry, it is the doers who really decide the direction of the instry, which is exactly where Huawei's culture lies. Huawei cloud Bu has been formally established for just one year, which not only shows its strength and sincerity to the instry, but also shows its low-key, pragmatic and honest attitude

on December 17, 2017, Huawei cloud and Tuowei Information System Co., Ltd. established cooperation to build nine public cloud instry solutions for the government and enterprises based on Huawei cloud; On January 27, 2018, Huawei cloud and UFIDA cloud jointly released four general enterprise services: Marketing cloud, collaboration cloud, tax cloud and U8 cloud; In February 2018, Huawei cloud officially released the deep learning service and blockchain service BCS; On March 15, 2018, Huawei cloud announced the opening of a Hong Kong data center to help enterprises reach the world and innovate in the future

the data shows that the number of Huawei cloud services has increased from 45 in 10 categories at the end of 2016 to more than 100 in 14 categories at present, including more than 60 solutions such as manufacturing, healthcare, EI enterprise intelligence, e-commerce, sap, HPC high performance computing, IOT, etc. Since the establishment of cloud Bu, the number of users and resource usage of Huawei cloud have increased three times

according to the market report from IDC, Huawei's cloud government cloud solutions are among the leading manufacturers in China's Government cloud market; Fusioncloud's private cloud solution ranks first in China
