Increasing demand for information systems, IT costs and information
system scales are increasing exponentially in the world. Cost Increasing
for information systems improved concern on the effectiveness of IT
investments, various of techniques have been proposed to solve the
investments effectiveness. Virtualization technology is introduced an
important technology that has increased the efficiency aspect of IT
investment. Desktop virtualization technology has to solve the problems
such as resource depletion, performance degradation and upgrade in the
course of operation of local computing systems. In addition, if convenient
virtualized user domain and security infrastructure are constructed in
virtualized independent environment, virtualized technology must need
support to respond and recover quickly when inner defect and service
disorder is occurred.
In this paper, we proposed new virtualization technology that is more
convenient and stable in local computing environment, then found
technique elements need to desktop virtualization which is based on
clients in various virtualization technologies. After running excution of
process explorer utility in user level virtualization and VMWare, we found
memory capacity that is used 30.1MB in VMWare and 16.6MB in user
level virtualization respectively to compare private bytes each of process.
We executed Alsogn, gom, Notepad and iexplore application program to
analysis of performance in local computing environment and user domain
with user level virtualization. Overhead of memory showed 2,296KB,
5275KB, 4052KB and 3,592KB memory capacity respectively. This result
showed that the rate of overhead is low when memory size of application
program is high. But the rate of overhead is high when the size of
memory is small such as notepad application program. Also, we found no
significant difference of CPU utilization which is executed application
program in local computing environment and user domain with user level
virtualization.
In this result, proposed vitualization technology is able to minimize
performance degradation of local computing envrionment. Also, we can
obtain efficiently effects that is separate user's an computing resource
from local computing systems while client's user use local computing
resource through virtualization.
