short period of time. Resource use planning and management are important
activities of the cloud. Handled properly, the plan will provide needed capacity
computing resources to create new solutions and to meet application performance
goals, promote teaching, and researching goals.
Conclusions
Cloud computing as an exciting development is a significant alternative today's in
educational perspective. Students and administrative personnel have the opportu-
nity to quickly and economically access various application platforms and resources
through the web pages on-demand. The gradually removal of software license costs,
hardware costs, and maintenance costs, respectively provides great flexibility to the
university/corporate management. From the points of advantages provided by
cloud, there is a great advantage for university IT staff to take them away the
responsibility of the maintenance burden in the university. Through the research we
believe that, we can create an e-learning application model based on cloud com-
puting by means of cloud computing's mass data storage, high-speed computing
capabilities, as well as its ideal allocation, and the sharing mode of resources. Some
problems such as platform security, technical standards, regulatory, and other
services are not well resolved yet in practice, pending further research and explo-
ration. Either way, e-learning application model based on cloud computing will not
stop its pace to proceed. As the cloud computing technologies become more
sophisticated and the applications of cloud computing become increasingly wide-
spread, e-learning will certainly usher in a new era of cloud computing.
Adopting cloud network redundancy eliminates disaster recovery risks and its
high costs. There can always be new tools and applications to improve IT features.
There are of course some disadvantages too. The cloud computing services needed
to deliver the majority of IT services needed by customers do not yet exist. There
are still problems and constraints with application offerings, service-level agree-
ments, more importantly security issues. All of the cloud providers do not have the
same capability for their technological levels.
