INTRODUCTION
Data centre Migration can be defied as a process that help in moving assets from one data
centre environment to another. It is further referred as data centre location. It can also be defied
as a way though which data centre from one operating location can be shifted to another without
causing any kind of data loss (Abdullah and et. al., 2020). This process does not require any kind
of physical movement. Virtualization is one of the best way with the help of which data centres
can be migrated from one environment to another virtually. With the help of virtualization IT
resources provisioning can be done easily. Today most of the organizations are focusing upon
data centre migration and migrating it to virtual environment as this virtualization helps in
reducing overall cost associated with IT resources (Huh, 2018). When expansion of an
organization take place it also require expansion or investment on more IT resources in such case
virtualization is extremely beneficial as it not only helps in sharing physical resources but it also
help in reducing cost associated with IT resources. This assessment is based upon a case study of
Global Healthcare Services (GHS) who wants to bring improvement within their technology for
reducing IT resources associated cost, take business driven decisions quickly by considering
virtualised platform. This assessment will further cover virtualization overview, Advantages of
virtualisation, software & hardware required to provide a virtualisation platform, high level
topology diagram to show how the virtualised environment, technical steps required to virtualise,
troubleshooting steps for basic issues with a virtualised environment and potential pitfalls or
problems with virtualization.
MAIN BODY
Overview of virtualization
Virtualization is a kind of technology that allows a person or an organization to create
useful IT services using all the resources that in traditional way are bound to a hardware system.
It further helps an organization to use a physical machine at its full capacity by distributing all of
its capabilities to other users and to environment in which it operates. Virtualization simply uses
a software for creation of an abstract layer over hardware of computer in order to allow a single
computer or system all the elements of hardware to be divided to multiple other systems of
computers that are most commonly known as virtual machines. These elements can be memory,
processor, storage, and many other elements (Nagesh, Kumar and Venkateswararao, 2017). All
the virtual machines behave like an independent computer system despite of the fact that it is
1

running on a particular portion of the original computer hardware. In order to utilize physical
computer in a more appropriate manner and helps an organization to return their organizational
hardware investment.
Today c has become important for organizations to be focused upon because it can help in
increasing IT flexibility, agility, scalability within a significant cost and by saving much more
cost. It can directly help in increasing availability of resources, performance, can help in
automating operations. It can also be said that virtualization can help in making IT much simpler
for management and can make ownership and operability of IT much simpler. Due to this, it has
become a standard practise among organizations IT architecture (Rashid and Chaturvedi, 2019).
On the other hand, rise in usage of cloud computing has further increased usage of virtualization
because all the cloud providers use this technology for using their system and for serving their
users. Use of virtualization technology can directly help GHS hospital to manage their IT
resources and manage their growing business and overcome traditional bare metal hosting
limitation.
In this a Software known as Hypervisors is used that helps in segregating physical
resources from virtual environment in which those resources are required. This software is either
installed on top of operating system or on hardware system. This is the only way organizations
virtualize. This software further helps in dividing physical resources so that virtual environment
can use those resources for virtualization.
Advantages of virtualisation of their server infrastructure over physical servers
There are various kinds of advantages that virtualization of server infrastructure can
provide to GHS organization over physical server. Some of the main advantages of virtualization
of server infrastructure over physical server are as follows.
 One of the main advantages of Virtualization of server infrastructure for GHS over physical
servers is saving on overall IT cost. Virtualization of server infrastructure can be done in
much lower cost whereas physical servers might require lot of cost to be used and deployed
(Prayudi and et. al., 2019). In this multiple operating system instances can be deployed and
operated on a single physical server which makes it much easier for organizations to manage
their servers and spend less amount on other servers.
 Virtualization of server infrastructure is much more beneficial as compared to physical
servers because virtualization helps in reducing requirement of physical servers that are
