CLOUD COMPUTING
Introduction
Cloud computing is a process of storing and managing data and information over internet.
Cloud storage makes use of a network of remote servers hosted on internet to store and process
data. Webb’s Stores has embarked on integrating their daily operations by implementing cloud
storage in order to reduce the operational complexity. The report discusses the different cloud
computing approach and different cloud architectures in use. The report draws a comparison
between Azure and AWS to decide which one is better to implement (Patidar, Rane & Jain,
2012). The advantages and the disadvantages of SaaS is discussed along with the comparison of
IaaS and PaaS approach. The report concludes with the recommended approach that webb’s store
can undertake.
1. Answer 1 (ppt)
1.1 Key Components of Cloud Computing and Webb’s benefit
3 | P a g e

CLOUD COMPUTING
Webb’s stores can make use of cloud storage to store, integrate and access their data and
resources. This will considerably help in integrating the their operation from both the data
centres.
1.2 Use of AWS or Azure
4 | P a g e

CLOUD COMPUTING
These service providers focus on excellent data services and ensure proper security of
data stored into the system.
1.3 Cloud Architecture to be used

CLOUD COMPUTING
AWS service provided by Amazon can simplify the operations of the Webb’s store by
providing remote computing services and access to the resources.
2. Answer 2 (ppt)
2.1. Advantages of using SaaS
7 | P a g e

CLOUD COMPUTING
SaaS provides a number of benefits in managing the IT infrastructure of a company.
Moreover, the service provider keeps a check of the updates and the client does not have to
worry or pay extra for installing the updates.
2.2. Disadvantages of using Saas
8 | P a g e

CLOUD COMPUTING
The disadvantages of SaaS further includes the performance degradation due to slower
speed and lack of control as only the latest version of the software can be used. Moreover, SaaS
offers a very limited range of application.
2.3 The SaaS service recommended

CLOUD COMPUTING
With the help of Microsoft office 365, real time sharing and monitoring of information
becomes possible. This will be of a great help to the webb’s store.
The major disadvantage of this software is that, it depends of the network for its
performance and the performance can be hampered with a slower internet connection.
3. Answer 3
3.1 IaaS Approach
11 | P a g e

CLOUD COMPUTING
Infrastructure as a service or IaaS is a service model for delivering computer
infrastructure in an outsourced basis for supporting the operations of enterprises. IaaS is a service
provider that works with providing virtual computer services over internet. In this approach, the
service provided of the cloud computing hosts hardware, storage and server components on
behalf of the user (Manvi & Shyam, 2014). Migration of database into cloud with the help of
IaaS approach offers numerous business advantages to the organizations. It is one of the basic
layers of cloud computing and provides virtualized computing resources over internet. Iaas
approach enables the transfer of data in an unchanged manner from the webb’s store s traditional
database to the cloud database. This implies no modification of data is required for the migration
and this is an advantage of Iaas Approach. Iaas moreover, provides a secure platform of data
storage and therefore it is a highly recommended approach (Kavis, 2014).
3.2. PaaS approach
PaaS or Platform as a service is a category of cloud computing that allows the developers
to build application and services over the virtual world or internet. The major advantage of cloud
is that, user can access their data simply with the help of a web browser. Customized application
can be developed using the PaaS approach. User has the control over the cloud infrastructure.
The customer created application can be created using programming languages, libraries and
services (Xu, 2012).
3.3 Advantages and Disadvantages of each approach
The advantages and disadvantages of IaaS and PaaS are elaborated in the following table.
IaaS Approach PaaS approach
Advantages 1) Customer can control and 1) low cost in comparison to IaaS
12 | P a g e

CLOUD COMPUTING
automate their own VM
2) enterprise integration feature
simplifies the integration of
operations
3)The approach is secure
4) low maintenance cost (Sadiku,
Musa & Momoh, 2014)
2) Users have full control over
the software
3) Improved integration support
4) VM needs minimal
management.
Disadvantages 1) Expensive as the initial cost is
very high (Dinh et al., 2013)
2) Customers are responsible for
backups
3) Customers has no control over
the server (Obrutsky, 2016)
1) User has no control over
platform depending on the cloud
provider.
2) The management of cloud is
time consuming
3) less cost effective than SaaS
(Singh et al., 2016).
3.4 Approach recommended
The recommended approach for Webb’s stores is definitely IaaS. This is because with the
help of IaaS approach, the data migration can be done more efficiently. Moreover, the IaaS
architecture is user friendly and offers numerous benefits. The scalability feature is one of them.
Although the installation cost is high, the long time benefit is much more in case of IaaS and
therefore, this feature is recommended. Moreover, it allows multiple users to access same data,
which is needed in case of Webb’s stores. This approach will definitely help in improving the
business. IaaS is an effective choice with no upfront investment and maintenance as it offers pay
as you go service, which implies the customer has to pay only if they use the services. The price
13 | P a g e

CLOUD COMPUTING
is calculated on basis of the units consumed and therefore, it is coast effective as well. IaaS can
be accessed from anywhere and therefore will be more beneficial for Webb’s.
Conclusion
Therefore, from the above discussion, it can be concluded that it is a wise decision taken
by the webb’s store to migrate its data to cloud server for integrating their operations. The cloud
architecture recommended to the Webb’s store is AWS architecture as it is the most cost efficient
architecture and provides numerous advantages. Data migration is an important aspect of cloud
implementation and therefore it needs proper attention. Different approaches are available for
data migration and accordingly, IaaS approach is considered to be the most effective one. This is
because the process of data migration is very simple and easy in case of IaaS approach and
therefore it is recommended.
