Cloud Computing for Webb's Stores

This assignment analyzes the suitability of Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) for migrating Webb's Stores database to the cloud. It compares the advantages and disadvantages of each approach, considering factors like cost, scalability, and ease of configuration. The report ultimately recommends PaaS as the most suitable option for Webb's Stores based on its benefits and lower implementation complexity.

VIRTUALIZATION AND CLOUD COMPUTING
Introduction
Cloud Computing is an online computing process which totally dependent on the web.
This is a type of process that allows the organizations to share resources without owning it. The
organizations are able to carry out certain functionalities without purchasing it or investing huge
amount of capital.
This report talks about the PaaS and IaaS approach that Webb’s Stores can use to move
its database to the cloud. This report gives a clear comparison between these two approaches. At
the end it also suggests an appropriate approach that will be suitable for this company.
IaaS approach of moving the database to the Cloud
The full form of IaaS is Infrastructure as a Service. This is one of the three service
models used in cloud computing. This approach will enable the Webb’s Stores to get access to
the storage facilities, virtual machines, network and storage services (Jadeja & Modi, 2012). This
service model also provides with the administration service along with hardware services.
In the IaaS approach the Webb’s Stores requires to develop an application ad install all
the required software that is needed to run in cloud. The virtual machine needs to be uploaded to
the environment of the host. This approach is suitable for Webb’s Stores when it has no time for
the process of reengineering applications. The first step that the company needs to do is to take a
technology domain in its account. The financial constraints must be met before migrating
through this approach. Certain conditions need to be met (Rittinghouse & Ransome, 2016). This
approach certain benefits and challenges. Here the company needs to be dependent on a third
party and there is a high chance of quality degradation. Other requirements for migrating the

database are dynamic resource need and data stream. This approach takes different steps from
that of the PaaS approach.
PaaS approach of moving the database to the Cloud
The full form of PaaS is Platform as a Service. This approach can be used by Webb’s
Stores when it requires a platform for developing applications along with storage facilities. They
provide software services like middleware (Wang et al., 2012). This platform will help Webb’s
Stores to develop and run application in a scalable as well as elastic environment. The initial step
that Webb’s Stores need to take is to configure Azure Web App and Azure SQL Database. There
is no need for the company to use the VM server and log in (Gibson et al., 2012). There are
several layers present in this approach and each layer has restrictions.
Advantages and Disadvantages of IaaS and PaaS approach

Advantages:
 This approach helps the company to
save any kind of huge capital
expenditure on the hardware.
 There is very little load of work
required in this approach.
 This approach requires no adaption
(Kavis, 2014).
 The migration process has no such
Advantages:
 This approach offers an easy procedure
for configuration.
 There is high scalability in the nature of
this approach.
 The availability is high
 It has the lowest expense.

complexity.
Disadvantages:
 This is the most costly approach.
 It is the responsibility of the customer
to manage the VM.
 The backup procedure is also carried by
the customer.
 The customers have no control the
virtual machine.
Disadvantages:
 Migration complexity is low.
 The workload during migration is also
low.
 The platform can be shared.
 Application modification is necessary
to make it compatible with PaaS
(Garrison, Kim & Wakefield, 2012).

Recommendations
The PaaS approach can be considered to be most suitable for the Webb’s Stores. The
reason behind this is that the company will get storage as well as application development
facility. This approach will be very easy for configuration and it has the lowest cost. There will
be less time consumption for Webb’s Stores to carry this approach and it will not affect its
productivity.
Conclusion
It can be concluded from this report that there are several approaches for moving
database to cloud. The most suitable approach for Webb’s Stores is PaaS. This report also
compares the PaaS and IaaS approach highlighting its benefits and loopholes.
