5. Methodology
Literature search was used to study related works and have
a comparison based on different studies and environments.
Cloud computing providers were selected according to their
capacity to handle large government projects and their global
vendor position. Cloud environments selected must have
IaaS, SaaS and PaaS capacity. On these, E-learning
component is integrated, Research Apps and Tools besides
other education based digital content approved by the
government. This study significantly diverts the resources
from the promised laptops to a framework where they are
used to setup a VDI to access the government owned cloud.
Virtual desktop infrastructure (VDI) is the practice of
hosting a desktop operating system within a virtual machine (VM) running on a centralized server. VDI is a variation on
the client/server computing model, sometimes referred to as
server-based computing. The term was coined by VMware
Inc. In the past couple of years, some large organizations
have turned to VDI as an alternative to the server-based
computing model used by Citrix and Microsoft Terminal
Services. (see Figure 1)
