Development and Evaluation of a Virtual PC Type Thin Client System - Data Management in Cloud, Grid and P2P Systems - page 112

In this paper, we give the problems we had when managing large-scale users in
a virtual PC system and suggest the solution. Specifically, we propose a method
for automating the initial settings at the time when a virtual desktop is delivered
to large-scale users. In addition, we propose the load dispersion method for when
there are obstacles and security measures. Furthermore, we show a performance
evaluation of the virtual PC system that we built, and we show how performance
level improves in comparison with the CB system.
2 Classification of Desktop Virtualization Technology
Desktop virtualization technologies can be classified into CB systems, TS sys-
tems, and virtual PC systems. We show a figure of each system in figure 1.
Fig. 1. CB, TS, and Virtual PC systems
2.1 CB System
The CB system is a method for putting a thin PC, called a gblade,h in an
exclusive rack. One user uses one blade. Because the CB system can install ap-
plications individually, making an environment that satisfies the needs of the
user is possible. However, because computing resources are not flexible, the pro-
cessing capacity may be low for a single blade; however, the processing capacity
of most blades remains. In addition, managing individual client OSs can be com-
plicated, e.g., virus measures are needed or a security patch needs to be issued
to every client OS.
2.2 TS System
The TS system is a method for operating a server OS with one server and
operating an application for multiple clients on a server OS. Because we can
flexibly use the hardware resources of a server amongst multiple clients at the
same time in a multiple desktop environment, we can make good use of them.
In addition, ecient operative management is possible because we can manage
applications and data intensively, but we cannot install applications individually.
