| Summary: | 碩士 === 南台科技大學 === 資訊管理系 === 100 === In recent years,
personal computer dominated the era is coming to an end,
it will be replaced by what we call "post-PC era".
Although the computing power of personal computers is growing,
but most of the computing resources are waste.
With the rise of cloud computing,
mobile technology continues to evolve,
and the architecture of personal computers will be replaced.
As long as people have the network will be able to use cloud datacenter to handle computing application.
When people has computing needs,
he can spend less cost and can immediately connect to the cloud datacenter, acquiring computing resources.
Cloud computing changes the future of personal computers into a new milestone.
For above reasons,
the purpose of this paper wants to improve IT resource utilization and application availability.
Fast and flexible adjustment of virtualization resources keep IT departments away from spending a lot of time for management and maintenance of physical machine,
and computing resources can be quantified.
Using Internet and through a specific interface to transfer the desktop resource and providing quantified desktop resource to be a service for the Users,
we also can strengthen the backup capacity of desktop data.
By discussing the approach of remote backup plan,
and ensuring security of system data.
How to manage the desktop as a service of cloud environment,
and how to import the desktop as a service are key issues in this paper.
We give recommendation for those issues and improve the success rate of importing and reduce investment risk.
We also build a cloud system won’t be interrupted and acquiring optimization of IT resource.
