What is Cloud Computing?
 “cloud” is methaphor for internet.
 The name cloud computing was
inspired by the cloud symbol that's
used to represent the Internet in
flowcharts and diagrams.
 Users simply rent or access the
software, paying only for what they
use
.

3.
History of Cloud Computing
 Concept dating back to the 1960’s by John McCarthy, a
computer scientist, brought up the idea that
"computation may someday be organized as a public
utility”
 Moving from clustering computing to grid computing this
idea revolutionized Cloud Computing

4.
Potential Issues
• Data residency – time delay between data being
requested and delivered
• Security and confidentiality of data being stored
outside the company
• Business buy-in; convincing companies of the
infrastructure and reliability

5.
Functionality
 Cloud computing is an emerging technology that is
revolutionizing IT infrastructures and flexibility, and
software as a service (SaaS)
 During this economic time of recession, there are huge
cost-reduction pressures and cloud computing allows
businesses to do just that by tapping into cloud computing
platforms on a pay-as-you-go basis
 Software and applications are extremely costly. With
cloud, you rent so the heavy investment is forgone

6.
Functionality CONTD…..
 Cloud computing is a set of technologies and business practices
that enable companies of all sizes to build, deploy, monitor and
scale applications using resources accessed over the internet
 A cloud can be private or public.A public cloud sells services to
anyone on the Internet. A private cloud is a proprietary
network or a data center that supplies hosted services to a
limited number of people
 The goal of cloud computing is to provide easy, scalable access
to computing resources and IT services.

Cloud Computing Usage

9.
Infrastructure as a Service
 Defined as delivery of
computer infrastructure as
a service
 Infrastructure providers
can dynamically allocate
resources for service
providers

10.
Platform as a Service
 Provides all the facilities
necessary to support the
complete process of
building and delivering
web applications and
services, all available over
the internet
 Infrastructure providers
can transparently alter
the platforms for their
customers’ unique needs

11.
Software as a Service
 Defined as service-on-
demand, where a provider
will license software tailored
 Customers can utilize
greater computing power
while saving on the
following
–
–
–
–
Cost
Space
Power Consumption
Facility

12.
• Reduced Hardware equipment for end users
• Improved Performance
• Lower Hardware and Software Maintenance
• Instant Software Updates
• Accessibility
• Less Expensive (Amazon example)
• Better Collaboration
• Pay for what you use
• Flexible

13.
• Security Issues
• Internet connection
• Too many platforms
• Location of Servers
• Time for Transition
• Speed

Future Educational Uses
 More useful spending of technology budgets
 Classroom collaboration
 Office Web Applications
 Google Docs

15.
Future Personal Uses
 No more backing up files to thumb drives or syncing
computers together
 Services replace devices
 A single hard drive for the rest of a person’s life, accessible
anywhere with internet
