The purpose of virtual desktop solutions is to revolutionize and simplify the user's current desktop system (Windows+PC), freeing them from the constraints of desktop devices and software on them.

The virtual desktop solution relies on virtual machines deployed on servers in user data centers, achieving virtualized desktops by separating operating systems and applications from client devices. There is no need to install application system client programs on the user's client devices, and these client programs are deployed on several small servers in the central computer room. By using a virtualized desktop system to directly push the operating system or applications to the end user's terminal device, users can obtain their own system environment or run applications directly.

Through virtual desktop solutions, users can benefit from the following significant benefits:

Reduce maintenance and management costs, and get rid of the busy situation of PC issues and updates all day long;

Greatly improve the speed of application software deployment, including software updates that only need to work in the central computer room;

Centralize the management of all critical data to avoid loss of core systems or data due to terminal security;

Effectively utilize resources and reduce system software and hardware investment through multi user reuse.

Virtual desktop solutions often require unified management and authentication system integration with users, achieving single sign on, and even portal system integration.

The schematic diagram of the virtual desktop solution structure is as follows:

Virtual desktop solutions are suitable for various user environments, such as library electronic reading or borrowing environments, software development and testing environments for enterprises, business hall systems for telecommunications or banking systems, network management systems for the telecommunications industry, call centers, government service window institutions (such as tax and business service halls), etc. In short, there are opportunities to deploy virtual desktop systems when a large number of PC environments are required, application software deployment is relatively complex or difficult to manage, desktop systems need to be kept clean and unified, and application software does not have strict performance requirements.

Solution composition:

The virtual desktop solution consists of a terminal layer, a virtual access layer, an application service layer, and a management layer. Among them:

(1) The terminal layer involves terminal equipment. In this scheme, it is a thin client, which reduces the investment in client equipment;

(2) The virtual access layer serves as the interface for terminal devices to access the backend virtual desktop or application programs, responds to user requests and forwards them to the correct backend server for processing, and then returns the results to the terminal devices. The devices in this layer are mainly server devices;

(3) The application service layer mainly processes user requests transferred from the virtual access layer, providing the processing results and interfaces that users need. This layer is the core component of this solution, involving server devices and storage devices. As the application service layer is the core of the system, it needs to be protected, such as data backup.

The virtual desktop solution is divided into two components: software and hardware, and the software part is mainly provided by three vendors - Sun, Citrix, and VMware. The hardware part includes the server and RAID. The following three manufacturers can be selected - Sun, IBM and HP. The backup software can choose Symantec NetBackup software.
