Cloud Computing: Applications, Benefits, and Infrastructure Analysis

This report provides an overview of cloud computing, detailing its core concepts, benefits, and various infrastructure models. It begins by defining cloud computing and highlighting its advantages, such as application development, testing, and transactional application design, while also addressing the importance of maintaining project privacy. The report then delves into the three main cloud computing infrastructure models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), explaining the characteristics and uses of each. References to relevant research papers are also included, offering a comprehensive understanding of cloud computing's applications and its role in modern technology.

CLOUD COMPUTING

Cloud Computing
The process of utilizing the network system
in order to fetch, store and modulate data
and distribute the same over the local servers
to the individual computing devices is known
as Cloud Computing (Abdullahi & Ngadi, 2016)

Benefits of Cloud Computing
Developing Cloud based application.
Utilizing cloud for developing and testing.
Designing transactional application using
block chain (Pahl, 2015).
Maintaining privacy for the existing project.

Developing Cloud computing based applications
The cloud application is the software based
program that is suitable for the cloud
platform. In case of the application that are
prepared to support in the cloud platform,
the components that are platform based and
local components are collaborated in order to
function efficiently.

Utilization of cloud for testing of the project
Cloud testing provides the business platform
the benefits of testing the applications that
are related to the services and the demands
of the clients who are related to the business
organization. Testing of the application
regarding the cost management of the
product is another benefit of using Cloud
platform.

Designing transactional application
Relational databases have proven to be
successful in the creation of transactional
application. As the relational database is
flexible and scalable in nature it is helpful for
the creating of the transactional application
in the cloud platform.

Maintaining privacy of the existing projects
The main probation of security possessed by
the cloud computing is by the means of: -
1. Authentication and authorization.
2. Confidentiality, Integrity and Availability.
3. Security Management.

Cloud computing infrastructure
IaaS infrastructure
PaaS infrastructure
SaaS infrastructure

IaaS Infrastructure
Infrastructure as a Service is the most
flexible form of the cloud computing
infrastructure (Bruneo, 2014).
IaaS should be used in this short coming as
the entire set up is to be changed.
IaaS is the recommendable architecture in
this case of upgrading the infrastructure to
the cloud computing system (Iosup, Prodan &
Epema, 2014).

PaaS Infrastructure
PaaS is the platform that is controlled by the
consumers of the software. Private services
inside the firewall is possible with the help of
the Platform as a Service (Gani, et al 2014).
The platform can be configured with the help
of utilizing middleware, database and storage
operating system (Iosup, Prodan & Epema, 2014).

SaaS Infrastructure
The major characteristics of the SaaS are: -
It automatically updates the system and the
updates are imposed to the system without the
customer concern.
The services that are provided by the SaaS
needs to be purchased in order to enjoy the
facilities of the infrastructure (Dillon & Vossen,
2015).
The software to be used by the consumers needs
to installed in order to gain the access to the
latest software.
