Abstract.
In recent years, it is thought that the virtualization of the
desktop is important as an effective solution to various problems that
a company has, such as cutting the total cost of desktop PCs that the
company owns, achieving eciency in operative management, and having
successful security measures, compliance measures, and business conti-
nuity plans. We introduced a client blade-type thin client system, called
a “CB system,” and a terminal service-type thin client system, called a
“TS system.” The number of users in all of our current group companies
is approximately 70,000. We built a virtual PC-type thin client system,
called a “virtual PC system,” as a new virtualization technology for the
desktop. In this paper, we give the problems we had when managing
large-scale users in a virtual PC system and suggest the solution.

1 Introduction
In recent years, it is thought that the virtualization of the desktop is important
as an effective solution to the various problems that a company has, such as
cutting the total cost of the desktop PCs that the company owns, achieving
eciency in operative management, and having security measures, compliance
measures, and business continuity plans.
According to the findings of documents [2], the client virtualization solution
market, which contains the desktop virtualization solution market, in Japan in
2011 was 249,300 million yen, up 31.7% from the previous year. It spread to
372,800 million yen, up 49.5%, from 2011 in 2012. It is projected to spread
to 771,500 million yen, up 17.7%, from 2015 in 2016, and the annual average
growth rate (CAGR: Compound Annual Growth Rate) from 2011 through 2016
is predicted to be 25.3%.
We introduce a client blade type thin client system, called a “CB system,” and
a terminal service type thin client system,calleda“TSsystem.”Thenumber
of users in all of our current group companies is approximately 70,000. We built
a virtual PC type thin client system, called a “virtual PC system,” as a new
virtualization technology for the desktop.
