Meanwhile, Cloud Desktop provides users with a personalized desktop and a variety of access methods, which improve service levels and business continuity needs. Compared with the traditional IT infrastructure, the Cloud Desktop provides users with faster & higher predictability, higher cost performance and richer applications.
