CLOUD STORAGE
Introduction
Cloud storage is one of the most popular models of data storage, where digital data or
information is stored in logical memory slots. It can also be defined as a service model that
maintains, manages and stores data remotely (Wang et al 2013). Users can then access this data
over any network, typically over the internet (Drago et al 2013). Cloud storage technology is a
need of the hour for almost any large scaled or medium scale business, in the modern times. Ji
etal (2013), says that big data industry specifically makes use of cloud services. However, many
are in the dilemma about the pros and cons of this remote storage technology. This report aims at
describing all the varied aspects of cloud computing or cloud storage by thoroughly visiting
every details of the technology. The report shall further outline the history of data storage over
the cloud-based network and finally highlight the advantages and disadvantages of this
technology.
Background: Cloud computing and Cloud-based Storage
Cloud computing has brought about a major change in the style of information storage
and the execution of varied applications more efficiently. Cloud storage is a crucial part of this
entire concept (Arora, Parashar and Transforming 2013). It curbs off the need to store huge
amounts of data and programs on a local desktop storage and instead provides a larger memory
space for storage on cluster of remote computers and or servers. In general, a cloud storage
architecture consists of a master control server and numerous storage servers that work
concurrently. According to Kavis (2014), typically, there are four types of scenarios where cloud
storage is used. They are as follows:

CLOUD STORAGE
 IaaS (Infrastructure as a Service): The service providers manages large sets of digital
resources. They use virtualization to intelligently use these resources in order to build an
ad-hoc system for the customer to rely on. This is a service-based scenario. This include
servers, networks, and storage modules and so on.
 PaaS (Platform as a Service): Clouds may also provide a platform for the clients to build
and execute their applications on. This is done by providing an additional abstraction
level.
 SaaS (Software as a Service): Software and applications are meant to run on these cloud
servers (Paraiso et al 2012).
 StaaS (Storage as a Service): This facilitates the cloud applications to scale beyond their
server limits. This is what allows users to store their data in remote memory locations
with the key to access them at any time and from anywhere. Cloud storage is meant to
fulfill tons of client side information about performance, reliability and data consistency
(Martini and Choo 2013).
A brief history of Cloud Storage
Joseph Carl Robnett Licklider is known to have invented the cloud storage technology
back in the 1960s. He developed this technology while working on the ARPNET network
architecture, in order to connect humans with data from anywhere and everywhere (Vibhute
2017). Back in 1983, CompuServe is believed to have offered the very first cloud storage facility
to their customers. They were given little amount of space to upload and store their data,
remotely. Since then, cloud service has become a crucial part of the digital society. Hosting
companies host remote servers and offers their clients with cloud based facility. Recently,
Amazon Web Services is considered to be the largest cloud service provider in the world. They

have grown enormously since their initiation in 2006. Google, IBM, SUN Microsystems and
Microsoft are the other famous competitors who excel in cloud-based service (Liu 2012).
A recent survey claims that the adoption rate of cloud based services and storage has
doubled in the past five years and the cloud services market is predicted to have reached nearly
$250 Billion by the dawn of 2018. However, debates about the acceptability of cloud-based
services over the traditional or local server-based storage have always been in the news. Below,
the advantages and disadvantages of adapting to the cloud based storage shall be discussed in
order to throw some light over the right uses of it.
Methodology
Methodology is the theoretical and systematic analysis of the methods applied to any
study of field. It defines the methods adapted towards to researching on a particular topic and
listing down the finding from it.
Here in this report, 12 quality research articles and web resources have been studied
thoroughly, in order to gain knowledge on the subject matter, that is being discussed.
Advantages of using Cloud Storage
The advantages of using cloud storage are as follows:
1. Cost and Maintenance: Cloud storage helps to cut back on the budget allocated for data
storage. It is much cheaper than implementing any in-house hosting or storage solution.
Moreover, it also takes off the burden of the maintenance cost from the respective
individual or company. Large business organizations are not needed to build nad
maintain huge servers for storing their data.

2. Accessibility: As it has been thoroughly stated in the earlier sections, cloud storage
allows file access from any place in the world. The data stored in the cloud is always just
a click away for its respective owner. A stable internet access and the valid identity
credentials facilitates remote access of the data (Cao et al 2012).
3. Recovery: It is a known fact that if data is deleted, it may sometimes be gone forever.
With the increasing digitalization of the modern society, the need to back up data is also
an urgency. Cloud storage provides that facility. Even if the user accidentally deletes
crucial data from his or her computer, it can easily be retrieved back if the data had been
uploaded on the cloud.
4. Synchronizing: The improved cloud servers allow their users to commit changes on
several files and folders, which are then automatically synchronized on the cloud server,
and are simultaneously made accessible across all devices. This facilitates the sharing and
concurrent analysis of data. In cloud servers that are meant to provide for software or
website based platforms, data synchronizing helps a great zeal to produce real-time
updates to both, the client and the administrator.
5. Enhanced Security: Being under the control of a hosting company who specializes in
cloud services, they tend to undertake every possible measure in order to ensure security.
They tend to add extra security layers and emphasize on added protocols to keep their
clients data safe. This prevents the data from being lost into wrong hands.
6. Avoid data redundancy: Typical cloud storage systems use high-end algorithms that
checks for data redundancy and eradicate the older versions of modified data, by updating
the contents with the recent modifications. This serves the purpose of efficient memory
management.

Disadvantages or Challenges in using Cloud Storage
The general challenges to be faced on cloud storage are:
1. Depending on Internet connection: As cloud applications can only run on the internet,
the experience is heavily dependent on how stable the user’s internet connections is.
2. Individual costing: Cloud storage service might be financially beneficial for large to
small-scale business forums; however, it may prove to be a costly choice of home
devices.
3. Customer Support: Studies suggest that customer support is a weak aspect of many
cloud storage service providers. They generally tend to ask their users to follow the FAQs
and online forums to resolve common issues that might generate on the client side.
4. Privacy issues: This is the most crucial challenge that cloud service have had to face
since the initiation of it. As the individuals or groups have to hand in their data to Third-
party storage providers, the risks of data breach arises. Certain ownership dilemmas are
also seen to rise in such situations, where it is hard to determine whether it is the client or
the hosting company, who shall be considered as the rightful owner of the respective data
(Drago et al 2013).
Findings
The points listed above, help to observe the reasons that give rise to the debating minds in
several community groups around the world. While the advantages of adapting to a cloud storage
technology are vast, however, the disadvantages sometimes demean the quality of it. It certainly
takes off the maintenance burden from the respective groups or individuals and lowers the
storage costing for large companies. Nevertheless, it is the duty of the hosting company to ensure

that the security measures are tight and of the correct standards, but however, a dilemma exists in
the minds of the data owners of whether to trust them in the process. This is a crucial step that
every company or individual must take before leveraging their data to the hosting service
providers. To excel in their services, the hosting companies must as well upgrade their customer
support facilities. However, for individuals this might be a simple option to simply backup their
important files and data, keeping in mind the purchasing prices of cloud hosting services.
Conclusion
The report helps to conclude that cloud storage, since the day it was invented have had its
eyes set to conquer the data storage facilities. Cloud technology also offers enormous data
storage capabilities to any individual or company. This enables the ability to store boundless
quantity of data and perform big data analysis. Big data is the current trend. Furthermore, the
report conveys the knowledge that cloud storage is just a coherent part of the larger picture that
is cloud computing, which allows more features. Finally, the discussion about the pros and cons
of the technology help to observe the advantages that an individual or organization can gain
through adapting to cloud storage. However, from the findings section it can be stated that the
cloud service providers may try to upgrade their security services and customer support facilities,
apart from legally committing to thread the ownership of the data solely to their owners.
