Explain virtualization and cloud computing

Virtualization is innovation that divides functions from hardware, while clouds depends on that
split. It's easy to complicate the two, particularly because the two of them spin around creating
valuable settings from abstract resources. The differences between the two can be describe
from a cloud computing model Infrastructure-as-a-Service (IaaS) standpoint. Stable Operating
System (OS) such as Linux lies at the base layer of cloud computing, that gives consumers
freedom across public, private, and hybrid environments. Assume access of intranet, internet,
or both is established, virtualization is what creates clouds. These resources can be cloud-based
applications containing all the runtime code, storage or any resources necessary for
deployment. Virtual resources should be allocated into centralized pools before they're called
clouds, and those clouds should be arranged by management and automation software before
it's viewed as cloud computing. Clouds convey the added advantages of self-service access,
automated infrastructure scaling, and dynamic resource pools, which differentiate it from
virtualization. While by protecting both the integrity of client’s virtual machines and the
components of cloud infrastructure, the security of cloud computing can be increase through
virtualization (Lombardi, F., & Di Pietro, R., 2011). Cloud computing permits access to all
authorized users without restriction while on Virtualization, proper authentication is required in
order to access the virtual machines. Multiple hardware creates cloud computing whereas
dedicated hardware is required for multiple virtual machines. In terms of integration, cloud
integration permits future expansion of users and applications whereas Virtualization
integration permits increase of new machines within the same infrastructure (Vaquero, L. M.,
Rodero-Merino, L., Caceres, J., & Lindner, M., 2009).

We can take an example of Green IT that has recently adopted virtualization. The main
objectives of Green IT are to reduce the IT operations negative impact on the atmosphere by
designing, developing, functioning and disposing of computers and its merchandises in an eco-
friendly way. The reasons to adapt Virtualization technology is to support organizations in
measuring their potential for undertaking Green IT initiatives, recognizing and investigating the
issues that contribute to the valuation of an organization’s willingness to go green.
Virtualization helps organization to minimize the use of harmful resources, make best use of
energy efficiency during the product's lifetime and supporting the biodegradability of unused
and outdated products. Virtualization technology can help respond to the requirement for
Reduce, Reuse, and Recycle (Bose, R., & Luo, X., 2011). With the increasing IT infrastructure
size, cost of energy and power is hitting the peak, holding expenses to a minimum is rapidly
becoming a highest priority concern. The technology lets a single computer or server
simultaneously run numerous operating frameworks or various sessions of a single Operating
system. The approach is accordingly turning into a typical way for users to boost their utilization
of hardware by increasing the number and sorts of jobs handle by a single CPU. The
organization is taking the benefits of Virtualization technology that has helped them in sizable
cost savings by consolidating their servers onto fewer pieces of hardware.
Initial post 2:
In this modern era of technology many companies are adopting Business Intelligence tools,
visualization tools and cloud tools to manage their data. Cloud computing have been a real deal
for companies that wants to grow in this era. When a company adopts cloud in its organization,
the data are easier to handle. The manual handle of data is now given to a cloud team who

takes care of all the challenges. Virtualization comes along with cloud computing as it is one of
the key components of cloud computing. When both virtualization and cloud computing are
taken into consideration company can have benefit and convenience. It gives a huge challenge
for data security and protection (Xing & Zhan, 1970).
There are many organizations that are using virtualization for their data security and protection.
It has become an integral part of the organization. The word virtualization is simply referring to
creating a virtual reality of something. For organizations adopting Virtualization, it lets one or
two more computers run with a single desktop. There are different types of virtualization that a
company uses. Some of the company uses Network virtualization, some uses storage
virtualization, and some uses services. Many companies adopt the cloud computing by getting
service from cloud-based service. The biggest provider of cloud computing are Microsoft with
Azure and Amazon.
AT&T is one of the companies is who is adopting virtualizations by 2020. They are stepping their
leg into adopting 75% of its network virtualized. AT&T already adopted virtualization back in
2013 and by the end of 2016 they were 30% using the virtual network (Robuck, 2019). AT&T is
using virtualization as a security tool in order to minimize the potential threat from its
competitors like T-Mobile, Sprint, Verizon. Nowadays there are cybercrimes, people are
attacking the walls of the established company, so it is best approach of AT&T to implement
75% of virtualization in its organization to reduce the threats from the hackers.
