Introduction:
The fundamental objective of this report is to critically analyze the journal which is
based in the topic of the data security, integrity as well as the availability of the data utilizing
the concept of cloud computing. Followed by the above aspects this report has effectively
discuss the focused area which has been discussed in the selected topic. After successfully
analyzing the research mentioned in the article in has been observe that the article in
fundamentally focused on the services of cloud computing. Followed by this aspects the
researcher has discussed about the security and privacy factors related to the services of cloud
computing in organizational framework. In order to support the research findings the
researcher has effectively analyzed the current as well as the future scope and issues in this
article. Considering all the above aspects this paper will address all the key points which has
been discussed in this article as well as it will also provide a brief knowledge on those areas
by elaborating the research methodologies, observations as well as the findings which has
been identified by the author [2]. Lastly, it will be concluded by stating the strengths and
limitations of this study and how it may help to gain knowledge about the operation of cloud
computing.
Discussion:
According to the study it has been noticed that Cloud computing holds one of the
significant impact of the services of small as well as in the large businesses by providing
effective solution related to the fast data access, cost effectiveness as well as it helps the
organization of reduces their man power which was previously needed for information
handling. In order to effectively discuss the aspect related to the data availability, data
security, integrity the researcher has effectively discussed about the characteristics of the
cloud computing in which it has identified that cloud computing is a on demand service
which means that the customer will pay for the resources which they have utilized not for the
resources which they have not utilized yet. Followed by this it has also mentioned that cloud
is based on the concept of global data accessibility as it offers to access the required data
from anywhere any place. Along with these there are several other characteristics also present
in the services of Cloud computing which includes the resources pooling, measured services
as well as the aspect of rapid elasticity by which it can extend the resources which is essential
for the rapidly growing organizations [1]. Followed by the discussion on the characteristics it
has also discussed about the service models and the deployment models of cloud computing.
According to the studies the cloud computing holds three services model and four

deployment models. The service models includes Software as a Service, Platform as a
Service and the Platform as a service, in which the SaaS offers to utilize the cloud
infrastructure to performs the organizational services, PaaS also works similarly by providing
the cloud platforms to the organizations however the major difference is it offers to deploy
the application into the cloud platform. Along with these IaaS offers the to utilize the cloud
infrastructure for entire computing operations which includes the utilization of cloud
operating system in order to deploy the application for organizational use [2]. Followed by
this four service model includes the private cloud, community cloud, public cloud, hybrid
cloud, in which the private cloud offers the accessibility to the cloud only to an organization,
Community cloud offers the accessibility of cloud services among a group of organization
which are internally connected however physically separated. Along with that the public
cloud offers an open accessibility as well as the hybrid cloud offers the cloud services by
combining three of the cloud deployment models [3]. Followed by the above aspects in the
selected paper it has effectively discussed about the threats related to the services of cloud
computing which has been identified by analyzing the previous organizational activities as
well as by analyzing the reviews. Those threats includes the data loss, infective insiders, as
well as the DoS attacks in which the researcher has discussed that since the organizations are
effectively utilizing the cloud services in order to store and manage their data there is a
significant risk present related to its data privacy as by analyzing the market threats it has
been noticed that any sort of cyber-attack significantly harm the information resource. Along
with that the study has also stated that there is a significant risk present related to the data loss
as if any attack happens the attacker can permanently delete the organizational data thus,
from this analysis the researcher has stated that there is a significant impact related to its data
privacy and loss [4]. Along with that while discussing the security issue of the cloud
operations one of the impactful concept of cloud computing has been accounted by the
researcher which includes the cloud virtualization. In order to discuss about the issues related
to the cloud virtualization in this article it has been mentioned that there is a significant risk
present in the concept of virtual machines. Those threats includes the cross attack of virtual
machine, image sharing of the virtual machines as well as the hypervisor issues which
represent the attacks by which the criminal infects the targeted cloud of an organization [5].
After successfully analyzing the article it has been noticed that along with the discussion
about the issues present in cloud virtualization there is a detail elaboration related to the data
integrity concept of cloud computing. The investigation on the concept of data integrity
present in this article has provide a knowledge that data integrity stands to protect the
