Cloud Computing In Higher Education HE Universities

Its about Cloud Computing and moving a University to use Cloud Computing instead of In-house Computing or both services as Hybrid.. please read the followings:

 Research into the concept of cloud computing and virtualization in Higher Education (HE) settings.
 You are required to base your research on 10 of the latest peer reviewed journal and conference papers.
 From this research exercise you need to identify:

o How HE institutions have adopted cloud computing and virtualisation into their IT services.
o What social and environmental impact cloud computing and virtualisation has had when used in the HE setting?
o Any legal and regulatory issues of using such a technology in a HE setting?
o Which are the most common HE departments and parts of the IT services selected for moving to the cloud computing realm?
o The most common deployment and service models used in HE settings along with the software platforms used to implement these models.
o Whether in-house cloud architecture was implemented or third party cloud computing services were used?
o What associated security risks were identified when the HE institutions switched to cloud computing and virtualisation and how these security concerns were addressed?
o What were the most common problems encountered when carrying out such an exercise?
