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

.

History of Cloud ComputingConcept 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

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

FunctionalityCloud 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

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.

Some Commercial Cloud Offerings

Cloud Computing Usage

Infrastructure as a ServiceDefined as delivery of

computer infrastructure as a service

Infrastructure providers can dynamically allocate resources for service providers

Platform as a ServiceProvides 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

Software as a ServiceDefined 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

Cloud Computing Pros• 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

Cloud Computing Cons• Security Issues

• Internet connection

• Too many platforms

• Location of Servers

• Time for Transition

• Speed

Future Educational UsesMore useful spending of technology budgets

Classroom collaboration

Office Web Applications

Google Docs

Future Personal UsesNo 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
