Desktop cloud is an application direction of cloud computing. As far as desktop cloud is concerned, its advantages are energy saving, easy management, convenient connection and improved resource utilization. At these levels, Huawei's solution should be similar to other solutions. The core advantage of desktop cloud lies in the maturity of its solution, and how to evaluate the maturity of a solution lies in the extent to which it conforms to the usage habits of pc when using desktop cloud for office. Therefore, the core of current technology lies in the end-to-end connection protocol. At present, this piece is a masterpiece, and Huawei's connection protocol seems to use Citrix. In fact, not only Huawei, but also Microsoft's ICP protocol was sold to him by Citrix. Due to the limitation of connection protocol, pc can not be completely replaced at present. For example, his support for ports and 3D graphics is his current bottleneck. However, for ordinary office work, there is no problem at all. Huawei claims to have established the world's largest desktop cloud office network, and Huawei has 70,000 engineers engaged in this work. It should be said that their technical maturity should not be a problem. In fact, if you have been in Huawei, you will understand why they use desktop cloud. They have very high requirements for the confidentiality of information, which is higher than that of ordinary government agencies. Desktop cloud can be well solved in this area.
