Cloud Computing Introduction and its Applications and Disadvantages

This assignment provides an introduction to cloud computing, explaining its fundamental concepts, including private, public, and hybrid cloud models. It further delves into different types of cloud services such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Recovery as a Service (RaaS). The assignment highlights the advantages of cloud computing, such as increased efficiency, improved mobile device performance, and reduced cyber-attack risks, while also addressing its disadvantages like high costs, limited resources, and security concerns. It concludes by discussing various applications of cloud computing, including its use as a backup plan, online data storage, and for e-commerce and web-based applications, referencing relevant literature.

Cloud Computing

Introduction
Cloud computing is an advanced technology
in the field of computer science
It is a kind of process to transfer information
technology services by using internet and
web based servers
There are main three parts of cloud
computing used:
 Private cloud
 Public cloud
 Hybrid cloud

Types of cloud computing
There are following types of cloud available
in market:
 Infrastructure as a service (IaaS)
 Platform as a services (PaaS)
 Software as a services (SaaS)
 Recovery as a services (RaaS)

Advantages of cloud computing
More efficient and flexible process
Increase performance of mobile devices
Reduced cyber-attacks
Very cheap and easy to understand
Consumers can use this process as a backup
plan [1].

Disadvantages of cloud computing
Very expansive process
Limited resources
Increased security risks and threats
Very complex to design
Users can lose their private details
Vulnerability to attack [2].

Applications
As a backup plan
Online data storage
Twitter related applications
Web- based applications
For e-commerce business
Word processing application
Spreadsheets
