Cloud computing is a new way of resource utilization on the Internet, can perform on-demand computing for heterogeneous and autonomous services on the Internet by mass users, and is dynamically and easily expanded and virtualized and provided through the Internet. Desktop clouds are a type of cloud that is well-defined by cloud computing, and which can access cross-platform applications, as well as the entire client desktop, through thin clients or any other network-connected devices. Currently, desktop clouds have public cloud schemes and private cloud schemes. In the public cloud scheme, a desktop cloud concentration deployment server provides cloud services for users through the internet. The public cloud scheme is based on the statistical multiplexing principle, so that system resources can be utilized to the greatest extent. However, the public cloud scheme has the following defects: when providing desktop cloud service, the Internet delay is high, the network is unstable, so that the remote operation response is slow, and the customer experience is poor; the internet bandwidth is limited and the capabilities of the server cannot be fully utilized. For example, the server can smoothly play video, and the remote user can only see the pictures with poor image quality due to the influence of the internet bandwidth. In the private cloud scheme, the desktop cloud is deployed on a server that the enterprise builds for individual use. Although the customer experience of private clouds is better than public clouds, the following drawbacks still exist: the infrastructure for constructing the private cloud must be purchased by the enterprise, and the system construction cost is relatively high; private cloud is built by the enterprise, cannot be shared in a larger range, and is low in system utilization rate.
To sum up, the prior art has two common problems, namely, firstly, high cost and regular cost performance of computer accessories: the higher performance and lower cost performance server requires expensive storage devices, virtual machine servers, and high performance network clients between the two require thin clients capable of resolving remote desktop protocols. Secondly, the deployment difficulty is high, high-performance centralized hardware equipment is adopted, initial investment is large, and a plurality of sets of professional software and hardware such as storage, virtual machines, desktop cloud management and the like are required to be maintained.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the embodiment of the present invention includes a storage server 1 for storing data, a plurality of local cloud terminals 2 for installing an operating system and allocating resources, and a plurality of local display devices 3 for displaying desktops, where the storage server 1 is connected to the plurality of local cloud terminals 2, the local display devices 3 are connected to the plurality of local cloud terminals 2 through independent graphics cards 4, and the storage server 1 is connected to the plurality of local cloud terminals 2 through a gigabit lan 5, and the present embodiment is structurally simplified to only three main components including the storage server 1, the plurality of local cloud terminals 2, and the local display devices 3, where the local display devices 3 may be implemented by using a liquid crystal display or an LED display, and the plurality of local cloud terminals 2 are implemented by using a plurality of independent hard disks carried by a high-performance host, and the storage server 1 is a main-stream high-capacity server with a medium-level or higher. In this embodiment, a plurality of independent graphics cards 4 for outputting images are mounted in the multi-path local cloud terminal 2, that is, the same CPU is used to carry more than two GPUs for displaying the desktop on each independent local display device 3, the invention mainly adopts the graphics card penetrating technology to realize the function, but only needs the existing structure on the connection structure, and the technical scheme is feasible for most civil-level graphics cards and control systems at present to realize the implementation by using graphics card penetrating.
The advantage of this embodiment is that the hot data and the cold data can be effectively and separately accessed, wherein the hot data is directly accessed locally, so the performance is far greater than that of a network storage mode, and the cold data itself has a small access amount, so local access is not required, and meanwhile, the structure of this embodiment does not need expensive initial purchase cost to purchase the storage server 1, the virtual machine server and the storage network device.
The independent display card 4 is arranged on the multipath local cloud terminal 2, and the local display device 3 and the multipath local cloud terminal 2 only carry out desktop protocol communication, so that the problem that the traditional desktop cloud communication data is overlarge and the cloud computing pressure is overlarge is solved.
