Understanding Virtualization Technology

This assignment explores the concept of virtualization, examining its applications in data centers and comparing it to cloud computing. It discusses the benefits of virtualization for organizations like Verbania, including reduced physical space requirements, improved resource utilization, and enhanced security. The assignment also analyzes the security considerations associated with virtualization and provides insights into best practices for mitigating risks.

Answer to question 1
Data centre virtualization is the process of virtualizing a data centre based on cloud
computing techniques. It virtualizes physical servers in a data centre along with networking,
storage and other physical infrastructures. It usually provides a virtual cloud. Virtual data centre
allows the placement of several virtual data centers on the same physical level of infrastructure
thereby making a hierarchy of centers capable of interconnection (Mijumbi et al., 2016). This
helps in IT optimization and reduces capital cost. Virtualization helps to create multiple
platforms in a same physical infrastructure level. The technology, which accounts for
virtualization is Virtual Machine Monitor (VMM) also called virtual manager, which separates
compute environment from the physical level. This technology will help Verbania in addressing
their system requirements.
Answer to question 2
Virtualization is considered to be an excellent method for reducing the need for physical
devices. In addition, virtual machines are considered to be specialized so that a physical location
is not mandatory for maintaining any such infrastructural components required. The first security
consideration includes the need to secure the virtual hard disks of the system. This will help in
reducing the need for security implications (Martins et al., 2014). As a virtual machine is more
prone to security breaches, the need for securing the assets are a necessity.
Another security consideration that can be included is to segment the traffic involved in
the whole architecture such that all the traffic can be monitored effectively from different

channels. Reduction in the attacks surface for the hosts is another security consideration which
also reduces the security breaches in the system.
Answer to question 3
Virtualization is termed as the technology which deals with reduced physical spaces
while cloud computing is the methodology applied for achieving that. In case of virtualization,
multiple environments made from simulators are made from 1 hardware system while in case of
cloud computing, an automated virtual resource pool is allocated for any on-demand uses of it.
Moreover, in case of virtualization, the delivery of packaged resources to specific users is
emphasized (Han et al., 2015). On the other hand, in case of cloud computing varied resources
are delivered to groups of users for specified tasks. Lastly, the configuration of a virtualized
system is always considered to be image-based while the configuration of a cloud computational
system is considered to be template-based.
Answer to question 4
Thus, virtualization is a good concept as it helps in reducing the need for physical
resources. This generally helps in creating a virtualized environment rather than a physical one.
In addition, Verbania can efficiently work using the applications which are directly installed in
the virtual server (Liang & Yu, 2015). Moreover, the company can also maintain a secure and
dedicated environment while doing so. Furthermore, the company can use their outdated
hardware by making instances and allocating virtual resources such that they can be used again.
This helps in increasing the profit and reduces the need for considering the overhead charges for
maintains any unnecessary physical resources.
