BUSINESS CASE FOR CLOUD
STORAGE ADOPTION

INTRODUCTION
 Presently, with the increase of data in the
companies, the requirement of additional
storage space is increasing immensely.
 The companies intend to store all their data in
the central storage from where the data could
be accessed easily by all the authenticated
users.
 The considered case study of the Telelink is
presently considering the implementation of the
cloud storage in the organisation for storing all
the data in a central place.
 The business is a medium sized
telecommunications company that is based in
Auckland.
 The company has efficiently grown to be among
the largest contact centres in New Zealand.

TELELINK As-Is ENVIRONMENT
 The present technology that is used is the on-premise servers that
are connects all the devices of the company in a central and it is used
by the organisation for storing all the data.
 The present architecture of the company is facing significant
difficulties in providing the required information to the employees
whenever it is required.
 As the number of customers of the business have increased, the
company is facing significant difficulties in managing all the
information of the customers in their database.
 The company is also facing major threats of data theft and this has
led to the increase of the need for implementing secured storage
location.

TELELINK As-Is ENVIRONMENT
(Contd…)
 The present TCO of the company is significant high as the company
needs several employees for the management of the servers of the
company and ensure that all the data of the company is secured
efficiently.
 The data of the company is managed in the database server where
additional security has been introduced for maintaining the security
of the servers.
 The aspect of governance in the company is mainly considered as the
systems and the processes that are used for ensuring that the
complete direction, the effectiveness, the supervision and the
accountability of the company.
 The governance of the company mainly ensures that the company
maintains the compliance with regulations and law

EVALUATION AND SELECTION OF
CLOUD SOLUTION
 Steps for choosing the most appropriate
cloud service provider are requirement
analysis,, suitability analysis, initial cloud
service selection, cloud service rating and
final selection
 Requirement analysis has been considered
as the most basic and initial requirement of
the cloud computing implementation.
 The main aim of this stage is gaining the
appropriate overview of the cloud
technology and the available cloud services.
 It has been analysed that the proper
understanding of the cloud computing helps
in increasing the efficiency as well as the
effectiveness of complete selection process
and then a deeper understanding could be
effectively gained.

EVALUATION AND SELECTION OF
CLOUD SOLUTION (Contd…)
 Suitability analysis is the next stage after the
preparation
 includes the execution of the suitability
analysis where the particular users are
required to efficiently ensure that this
technology of the cloud computing is
suitable under the provided requirements
 else it might be appropriate to stop the
selection process of the cloud service and
then retain the prevailing system in the
organisation or even implement any other
alternative.
 The proper execution of the suitability
analysis mainly helps with the analysis of the
business functions that would gain the most

EVALUATION AND SELECTION OF
CLOUD SOLUTION (Contd…)
 After the selection of the most
appropriate cloud computing model,
the next stage is the identification of
the set of the possible cloud
services.
 These kinds of pre-selection is
mainly required due to the fact that
the rating of the services is highly
demanding and significantly time-
consuming
 Initially, it is required to determine
which of services model is most
suitable.
 With the discovery of the most
appropriate service model, the

EVALUATION AND SELECTION OF
CLOUD SOLUTION (Contd…)
 After the completion of the stage of
selection of appropriate cloud service,
the stage of comparison as well as
ranking the service model is required to
be executed.
 This particular ranking could be easily
interpreted as the multi-criteria decision
making issue and this work utilises AHP
method or the Analytic Hierarchy
Process, which is most popular for
solving this particular problem.
 After completing the rating, the
multiplication of the weights could be
done for all the hierarchy and then the
multiplication of the resulting weight is
done with the linked rating.

EVALUATION AND SELECTION OF
CLOUD SOLUTION (Contd…)
 In the stage of final selection, almost
two or three options that are best
ranked are investigated further
 With the execution of an exhaustive
research using the internet might
provide some essential insights
regarding the solutions that are highest
ranked and it could lead to the most
elaborated ultimate selection.
 The service provider is contacted and
SLA is developed for ensuring a
confidential bond among the company
and the service provider
 SLA helps with improving the service
that is provided by the service provider
to the company

OVERVIEW OF CLOUD SERVICE
PROVIDER

considered as the web service that offers the
resizable capacity of computation within the
cloud storage.

OVERVIEW OF CLOUD SERVICE PROVIDER
(Contd….)
 The interface of Amazon EC2’s simple web service
permits the organisation to gain and then configure
the required capacity with the use of minimal
friction.
 The main feature of the AWS is feature of
autoscaling. The autoscaling of the Amazon web
service permits the users to the scale the capacity of
the cloud storage as per the requirement that are
defined by the users (Bates et al. 2017)
 The elastic load balancing of AWS mainly permits the
automatic distribution of the incoming application
traffic across various instances of Amazon EC2
 allows in achieving significantly greater fault
tolerance within the applications, seamlessly offering
the required amount of the load balancing capability
required for responding to the incoming traffic of
applications (Kaul, Agarwal and Raj 2018)

OVERVIEW OF CLOUD SERVICE PROVIDER

 Amazon workspaces could be described as the
completely managed desktop computing
service within the cloud
 The Amazon workspaces mainly permits the
customers with the easy provisioning of the
cloud based desktops that permits the end
users with accessing the documents, resources
and the applications that are required along
with device of their preference, that includes
laptops, Android tablets and iPad (Kotas,
Naughton and Imam 2018)
 Amazon virtual private cloud permits the users
with the provisioning of significantly isolated
section of AWS cloud where the AWS resources
could be launched in the virtual network that
could be defined by the users

OVERVIEW OF CLOUD SERVICE PROVIDER
(Contd….)  The network configuration could be
easily customised with the help of the
Amazon VPC
 Amazon route 53 could be considered
as another feature of Amazon web
services that is the highly available as
well as scalable DNS web service
 It is mainly designed for providing the
developers and the businesses with
the extremely reliable and the cost
effective method of routing the end
users to the internet application (Liao,
Kuai and Leau 2015)
 The designing of the Amazon Route
53 is done for being significantly fast,
easy to utilise and cost effective

OVERVIEW OF CLOUD SERVICE PROVIDER

web service, which mainly makes is easy to
configure, scale and operate any relational
database within the cloud storage.
 It offers the required cost-effective as well as
the resizable capacity while management of
time-consuming tasks of data administration,
allowing the significant focussing on the
business and applications
 The Amazon RDS mainly provides the required
access to all the capabilities of any familiar
MySQL, SQL server or Oracle database (Liu et
al. 2015)
 This denotes that all the code, tools and the
application that are presently used by the
company in the existing database could be
effectively used with the Amazon RDS.

OVERVIEW OF CLOUD SERVICE PROVIDER
(Contd….)

minimum costs.
 The speed of AWS has been considered as
the major benefit for the businesses. It
provides all the required computing power
within the minimal time and cost
(Medvedev et al. 2017).
 The web service mainly provides the
innovation and scaling while maintaining
the secure environment and it is mainly
required to pay solely for the services that
are utilised.

CRTICIAL ASSUMPTIONS AND
CONSTRAINTS
 It is required to ensure that root account of the users are significantly
secure.
 The company needs to introduce the two factor authentication in the
cloud environment for securing the data of the cloud.
 The company should introduce the infrastructure that is webscale
external facing when the cloud is adopted in the company.
 The private servers could be quickly protected from any external
access.
 Addition of the access restriction to the cloud security checklist is
required to be made, which is the maintaining access solely within
the region or restricted IP addresses.
 Public key infrastructure is required to be introduced in the
organisation as the part of cloud security policies.

METHOD OF MIGRATION TO CLOUD
 Migration to the cloud computing could be done in five stages, that
includes planning and assessment, migration tools, AWS cloud
storage selection, migration strategies and the application migration
method
 the financial assessment, security and compliance assessment and
the technical and functional assessment is required to be done.
 The financial assessment helps the organisation with estimating the
cost of moving all the data to the AWS cloud.
 As data security is considered as a challenging task, the company
needs to understand the major threats, risks and then the data is
required to be classified into appropriate categories.

METHOD OF MIGRATION TO CLOUD
(Contd….)
 The technical and functional assessment mainly helps with
understanding the applications that are most suitable to cloud
computing architecturally and strategically.
 The migration tools that could be used by the Telelink Company for
migrating the data to cloud are S3 command line interface, AWS
import / export snowball, AWS snowmobile, and Amazon Kinesis
Firehose.
 As the Telelink Company needs storing and querying the structured
relational and referential data, the Amazon RDS is the most suitable
storage option for the company.
 The Forklift migration strategy is the most appropriate strategy that
could be used by the company.
 The live migration could be considered as the most appropriate
application migration option for the company.

CONCLUSION
 Therefore, from the analysis of the above discussion, it could be
concluded that the organisation should consider the migration of all
the aspects of business to the cloud storage as it would provide
several additional benefits to the company.
 The main benefits that would be gained by the company would be
increase in security to the data, improved availability of the data to
the employees and customers, and the reduction of the cost of
maintenance of the business prospects.
 The present As-Is environment of the company is unable to provide
the extensive data availability to the employees but with the
introduction of the cloud computing in the organisation, the data
availability would be significantly improved.
