Cloud Computing Approaches: IaaS vs PaaS for Webb's Database

This report examines cloud computing approaches, specifically IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), for migrating Webb's database to the cloud. It begins with an executive summary and table of contents, followed by introductions to IaaS and PaaS, explaining their functionalities and applications within a business context. The report then compares the advantages and disadvantages of both approaches, highlighting IaaS's strengths in terms of security and user control, while also acknowledging its higher cost. PaaS is presented as a cost-effective alternative but with limitations in user control. The report concludes by recommending IaaS as the more suitable approach for Webb's, considering its benefits outweigh the drawbacks for the company's management system. References to relevant research papers are included to support the analysis.

CLOUD COMPUTING APPROACHES
Executive Summary
This report focuses on the various approaches that can be made in order to introduce Cloud
computing in Webb’s. This report discusses on two common approaches that can be integrated in
Webb’s for enhancing the management planning. Both of the approaches are good at their place
but IaaS in this report has been recommended as better than PaaS approach. The advantages and
disadvantages of both the approaches have been compared in this report to prove that IaaS will
be a better approach.

CLOUD COMPUTING APPROACHES
Introduction
In one line Cloud Computing can be defined as a general term to deliver hosted services
over the internet. It is applicable in various sectors including business in which it enables the
companies to consume computer resources which can be listed as: applications, storage and
virtual machines (VM) as a utility.
IaaS Approach to Migrating Webb’s Database to the Cloud
IaaS (Infrastructure as a Service) is a self service model which can be implemented in
Webb’s to monitor, manage and access the data and information produced by all the stores
situated at different places on the business. This will give access the employees at different stores
to achieve business calculations and produce outputs faster (Gueye et al., 2014). IaaS provides
full access to the users about the runtime, data, and middleware of the applications being used for
different operations. It is a package provided by various service providers which can be easily
purchased and a user can enjoy the benefits like cloud storage, quick computation and many
more.
PaaS Approach to Migrating Webb’s Database to the Cloud
PaaS (Platform as a Service) is also another architect of cloud computing which can
provide Webb’s a better framework of how and what applications are needed for the daily
operations of stores of Webb’s. It is an appropriate service for developing, testing and deploying
applications which can have positive impact on Webb’s in simple and cost-effective way
(McGrath, 2012). PaaS applications inherit various cloud characteristics, some of them are,

scalability of storage, SaaS enablement, on-demand availability, etc. This is a completely hosted
system in which customer is not responsible for any data updates and miscalculation.
Advantages and Disadvantages of IaaS and PaaS approaches
Advantages (IaaS) Advantages (Paas) Disadvantages (IaaS) Disadvantages (Paas)
 Most secure Cloud
services as compared
to any service
 Full control to users
to the processing data
and Virtual machine
(VM) (Sadiku,
Mussa & Momoh,
2014).
 Proper user interface
and access to the
middleware.
 Cost-effective as
compared to IaaS
 Allows user to run
application of their
interest (Mollah,
Islam & Islam,
2012).
 Hosted network is
provided by services
so users are free of
allegation for any
miscalculation or
wrong data input.
 Customers feed the
data input into the
database makes only
user responsible for
any backup and
other management
system
 Less control over
the physical location
of the database.
 Not much cost-
effective than PaaS
 Security risk
 Security lead to the
privacy risk to the
information and
data saved in the
database
 In this service tasks
that include
management are
more time
consuming than
another services.
Recommended Approach
Based on the above table which relates advantages, disadvantages of IaaS and PaaS
approaches it can be said that IaaS is a better approach for Webb’s management system. Stores
located at different places ca also have access to these applications and can upload their data over
the internet or cloud. This will help the directors to monitor and plan the next steps which need

to be taken in order to benefits the Webb’s. Excluding the ‘expensive cost’ disadvantage rest of
the disadvantages will not hamper much to Webb’s, so advantages are sufficient enough to
implement this approach.
Conclusion
The information presented in the above report is enough to conclude that cloud
computing can change the face of the management of Webb’s by allowing users to use various
effective and efficient applications provided in IaaS services. This approach will help in leading
Webb’s to achieve its goals.
