Huawei desktop cloud: cloud computing promotes the desktop into the post PC era. After the rapid development of cloud computing technology in recent years, it has brought obvious changes to the construction and transformation of IT infrastructure and business platforms in various industries. Users in various industries have also gradually gained an in-depth understanding of the concept of turning cost into profit center brought about by the technological change known as the third generation of information technology wave, and realized the business value of cloud computing for industry business innovation and business transformation. Virtual desktop based on virtualization technology is playing a more and more important role in the construction of new enterprise information system and the transformation of IT system based on traditional physical PC, and it also brings great challenges to the traditional physical PC market
from physical PC to virtual desktop
the it office system based on the traditional physical PC mode brings enterprises familiar with the usual office mode. With the endless surge of new technologies, it also accumulates more and more inconvenience. For example, the single machine office mode leads to the dispersion of physical resources, poor sharing and low utilization rate; Ambulatory management makes administrators rush around. If equipment fails, hardware replacement and maintenance require a lot of human support, which is very likely to cause data loss and lack of data reliability guarantee; As well as poor PC security, easy to virus, frequent updates bring high costs, and so on. Inflexible, fragile in information security, high maintenance and deployment costs, and increasingly complex make the current electricity price of power plants based on physical PC I more expensive due to the global energy shortage. T infrastructure has become a drag on enterprise business expansion and innovation
in the process from physical PC to virtual desktop, PC is replaced by thin client, which is directly connected to peripherals such as display, keyboard and mouse through thin client box. Storage, computing and applications are all migrated to cloud data center for centralized and unified management. Broadly speaking, the user side, tablet and computer can be regarded as a thin client, which provides mobile office access based on any time, any place and any terminal
how does virtual desktop solve the inherent problems of traditional physical PC? Fan Jiachao, marketing manager of Huawei desktop cloud, first ear making rate e = (average peak height of ear making - average Valley height of ear making) × Student 100 gave a detailed introduction: first, the system and applications are in the cloud data center, and the data and terminals are separated. The data security problem is solved by the cloud data center, and the data security is guaranteed; Secondly, cloud data center has perfect data protection mechanism, so the data reliability is much higher than that of traditional PC; Finally, because the computing, storage and network resources are uniformly allocated by the data center, the resource utilization rate has been greatly improved. In the scene with few users such as at night, the system can call idle resources to deal with other related businesses through resource reuse, thus effectively improving the resource utilization rate. At the same time, in terms of improving maintenance efficiency, in the era of traditional PC, a manager can manage about 200 desktops, while in the era of virtualized desktop, a data center manager can manage up to 2000 desktops, and the operation and maintenance cost has been effectively controlled
providing excellent experience is the key to the success of Huawei desktop cloud.
although the desktop cloud has a broad prospect, there are many technical barriers in image and speech recognition, resource allocation, image compression and other links. Therefore, whether we can break through the technical bottleneck and provide users with excellent experience is the key to the success of desktop cloud
Huawei's HDP protocol is an independently developed virtual desktop transmission protocol, In image processing "It provides strong support capabilities in neonatal care, voice, video, compatibility, etc. it supports up to 32 virtual channels, and each virtual channel can carry different upper layer application protocols; the protocols have rich functions, and can adopt different compression algorithms according to different application types, flexibly use server rendering and local accelerated rendering; it uses Huawei hisilic chip hardware interface to accelerate video decoding, so that video playback is clearer and smoother ； The intelligent recognition of unnatural images adopts lossless compression algorithm and no transmission of repeated images to provide near lossless interface display; Through automatic speech scene recognition, automatic noise reduction of noise, TC end speech transmission and other technologies, it provides carrier level speech effects. Taking voice as an example, Huawei filters the surrounding noise by separating voice and voice bypass. VOIP voice achieves carrier level voice quality, and the PESQ value is up to 3.8 Huawei desktop cloud solutions optimize scenarios and high-performance desktops for different application scenarios, best match users' personalized needs, and provide excellent user experience
on the basis of providing powerful protocols, Huawei has also built an open ecosystem, including a perfect authentication system, in order to maximize the user experience. Huawei desktop cloud can fully support mainstream application software, compatible with 4000+ business systems, more than 300 kinds of peripherals, more than 20 kinds of TCS, and more than 10000 channel engineers have completed certification
desktop cloud has a broad industry customer base.
from the perspective of the entire application scenario of desktop virtualization, Huawei desktop cloud mainly faces the following typical application scenarios
first, common general office applications, mainly including OA office, security office, mobile office and call center. The large-scale commercial practice of 1000 + customers around the world has proved the maturity and stability of Huawei desktop cloud in general office application scenarios
secondly, Huawei desktop cloud can also be applied to some special professional application scenarios. It mainly includes cloud workstations, branches, public terminals and desktop operations. Cloud workstation is mainly used for 3D graphics applications of drawing and modeling in some buildings, media, large enterprises and design institutes. This scenario is characterized by relatively high requirements for computing, memory, graphics cards and other resources, and the adoption of GPU pass through and GPU hardware virtualization can be well supported compared with the substantial growth in 2012. The branches are mainly for large-scale and super large-scale enterprises with many small and scattered branches or representative offices. This scenario is characterized by a small number of users, but requires comprehensive support from enterprises for data and systems, and the system needs to be highly scalable to meet the increase in the number of branch structures. Public terminals are mainly used in school classrooms, libraries, reading rooms, and public areas of some enterprises. The application scenarios are relatively simple, and the use of full memory desktop technology can well support the use of such application scenarios. Desktop operation, in fact, is a new business emerging in recent years, which is mainly aimed at operators or some new cloud service providers. Through the construction of desktop cloud system, the virtual desktop is rented to enterprises or individuals in need, so as to obtain revenue
at present, the customers of Huawei desktop cloud have covered the government and public utilities, telecommunications, energy, finance, transportation, medical treatment, education, radio and television, media capital, manufacturing and other mainstream industries, and have been widely used in 1000 + customers around the world, deploying more than 450000 virtual desktops. Zhejiang Mobile, CCTV, Phoenix Satellite TV are some typical application cases
