UUNZ Global IS Strategy: Telelink Cloud Storage Business Case Analysis

This case study examines the business case for Telelink, a medium-sized telecommunications company in Auckland, to adopt cloud storage. The company currently uses on-premise servers and faces challenges in data access, customer information management, and data security. The analysis evaluates cloud solutions, focusing on AWS, and outlines the selection process, including requirement and suitability analysis, cloud service selection and rating, and final selection. The study highlights AWS features like EC2, autoscaling, elastic load balancing, Workspaces, VPC, Route 53, and RDS. It also covers critical assumptions, constraints, migration methods (planning, tools, strategies), and investment considerations, concluding that cloud migration offers improved data security, availability, and cost reduction. The study emphasizes the benefits of cloud adoption for Telelink.

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
 The cloud service provider that have been
selected for Telelink is AWS or Amazon Web
Services(Amazon 2015).
 The AWS is the comprehensive platform of cloud
services that provides the required computing
power, content delivery, storage, and several
other functionality that could be used by the
organisation for deploying the applications as
well as services in significantly cost-effective
manner with major flexibility, scalability, as well
as reliability (Basha, Jilani and Arun 2016)
 The AWS self service mainly denotes that the
users could proactively address the internal
plans and then react to any external when the
selection is done
 The Amazon Elastic Compute Cloud could be
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
(Contd….)
 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
