Cloud computing implementation. The state of readiness of College of Health Sciences, Korle – Bu campus (PDF)

Magisterarbeit aus dem Jahr 2014 im Fachbereich Informatik - Internet, neue Technologien, , Veranstaltung: information Technology, Sprache: Deutsch, Abstract: Cloud computing can also be said to be a new style of computing in which dynamically scalable
and often virtualized resources are provided as a services over the internet. Cloud computing has
become a significant technology trend, and many experts expect that cloud computing will
reshape information technology (IT) processes and the IT marketplace. In addition, cloud
computing is a model providing access to the computing resources collection which match and
can be implemented easily without much intervention from service providers. The perception of
security technology, effectiveness, reliability, and also the cost effectiveness needs become
important elements in someone’s decision to recommend the technology on its organization
(Robert & Pick, 2004).
Nowadays lot of servers are used inefficiently because they are underutilized. The uses of cloud
computing associate to virtualization have been a solution to the underutilisation of those
servers. However the virtualization performances with cloud computing cannot offers
performances equal to the native performances.
The aim of the project is to evaluate cloud computing environment. It will outline the
performance that a customer can expect for public and private cloud. It will critically review the
different deployments of cloud computing and study the different solutions both Open-Source
and commercial that can be used with cloud computing. Further identify design scenarios for the
optimum performances of both public and private cloud and the tools available for the
implementation of cloud computing.
The results obtains through those experiments have outline the performances of public cloud and
shows that the virtualization of Linux gives better performances than the virtualization of
Windows. This is explained by the fact that Linux is using para vitualization while Windows is
using HVM. The evaluation of performances on the private cloud has permitted the comparison
of native performance with para virtualization and HVM. It has been seen that para
virtualization has performances really close to the native performances contrary to HVM.
Finally it has been presented the cost of the different solutions and their advantages.
