Desktop virtualization is the installation of a virtual host system on a physical server, which simulates the hardware resources required for the operation of the operating system, such as CPU, memory, network cards, storage, etc. The operating system runs on these virtual hardware resources, allowing multiple operating systems to share the hardware resources of physical servers, thereby improving resource utilization. The storage and execution of virtual desktops (including operating systems, applications, and user data) are centralized in data centers, and users access them through remote protocols (such as RDP, ICA, PCoIP) using terminal devices. Desktop virtualization hosts and centrally manages all desktop virtual machines in the data center; At the same time, users can obtain a complete PC user experience. Users can obtain the same user experience as traditional PCs through thin client or similar devices for local area network or remote access. It is a technology that only presents the operating system desktop to the user and performs calculations on the server-side. It can be combined with server virtualization and application virtualization.

function

The functions provided by desktop virtualization solutions mainly include basic functions, user convenience requirements, application virtualization, maintenance management, and reliability. Among them, the basic functions include multiple ways of access, support for undifferentiated multi application access, support for multiple virtual machines, support for mainstream operating systems, and support for mainstream storage technologies; User convenience requirements include the system being accessible anytime, anywhere and supporting personalized desktops, SSO support, dynamic allocation of network storage space, and support for audio input and output; Application virtualization refers to separating applications from the underlying operating system and supporting seamless integration between virtual desktops and application software virtualization; In addition, desktop virtualization also needs to support multiple deployment and maintenance methods, provide rich management and maintenance methods, and have carrier level compatibility and reliability.

characteristic

1. Fast and flexible deployment: on-demand application, quick distribution, no need to transport heavy PC hosts, unified access, anytime, anywhere access;

2. Improve resource utilization: Unify the management of backend data center resources and perform unified scheduling management to maximize resource utilization;

3. Data storage is secure and reliable: Data is stored in the backend data center, which is secure and reliable. And when accessing the virtual desktop, only image information is transmitted over the network, which is not easily stolen by others through the network;

4. Convenient maintenance: Thin terminals do not require software maintenance; Virtual desktop maintenance work can be carried out uniformly in the background, which is very convenient;

5. Energy saving and emission reduction: Adopting a desktop virtualization system, due to the low power consumption of thin terminals and the high resource utilization rate of data centers, the goal of cost savings and energy saving and emission reduction can be achieved.
