Abstract: Aiming at the decentralization of management, diversification of terminal configuration, and difficulty in data security faced by college public computer laboratories, a cloud desktop application scheme based on VDI technology is proposed and realized. Relying on broad-bandwidth campus network and virtualization technology,physical computers distributed in various laboratories are utilized to establish corresponding cloud desktop computers on high-performance servers in data center, realizing centralized and unified management of computing and storage resource as well as system deployment and maintenance. The experiment proves that the current scheme can effectively improve the computing and storage resource deployment flexibility and solve the security problems of terminal and user data.

Key words: VDI, cloud desktop, virtualization, data security
