What is Cloud Computing

• Cloud” is simply a metaphor for the internet

• Users do not have or need knowledge, control, ownership in the computer infrastructure

• Users simply rent or access the software, paying only for what they use

• Simple Introduction to Cloud Computing

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”

• Idea that revolutionized Cloud Computing: Moving from clustering computing to grid computing

– Clustering

– Grid

• “In some ways, the cloud is a natural next step from the grid-utility model,” said Frank Gens, an

analyst at the research firm IDC

The “Super Computer” in the Sky

• Two ways of building a “super computer” with enough power that users can plug into according

to their needs at a particular timeue Gene Appracho

Google's Approach

Early Leaders in the INDUSTRY:

• In 2007, Microsoft made available free software, www.live.com that connects its Windows

operating system to software services delivered on the Internet

• Launched in July 2002, Amazon Web Services provided online services for other web sites or

client-side applications

• 3tera launched its AppLogic system in February, 2006

• IBM’s system introduced in the mid 2000’s is called Blue Cloud

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

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

• Customer retention is vital, especially today in our economy.

Functionality

• Software and applications are extremely costly. With cloud, you rent so the heavy investment is

forgone

• 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

What Technologies is Cloud Computing Replacing

• Cloud computing is replacing large Corporate Data Centers and unnecessary, expensive private

server infrastructure.

• Web 2.0, SaaS, Enterprise and government users are adopting cloud computing because it

eliminates capital investment in hardware and facilities as well as reduces operations labor

Companies Leading in Cloud Computing

“Google 101”

– Network made up of millions of cheap servers, that would store staggering amounts of

data, including numerous copies of the world wide web

– Makes search faster, helping ferret out answers to billions of queries in a fraction of a

second

• Google has invested more than $2 billion a year in data centers for cloud computing.

• By far the leader in the technology

• Marissa Mayer, Vice President, Search Products & User Experience, talks about Google Clouds,

its product, uncertainties and future expansions and ideas.

• Amazon Elastic Compute Cloud “Amazon EC2”

– web service interface that provides resizable computing capacity in a cloud

– designed to make web-scale computing easier for developers

– reduces the time required to obtain and boot new server space from weeks to minutes

– allows developers to pay only for capacity that they actually use

• “Azure”

– Internet-scale cloud computing and services platform hosted in Microsoft data centers

– Provides a range of functionality to build applications that span from consumer web to

enterprise scenarios

– Designed to help developers quickly and easily create, deploy, manage, and distribute

web services and applications on the internet.

Scalable Pricing and Cloud Computing

• Models of Pricing

– Free

– Subscription Model

– Pay Per Use

– Perpetual License

– Enterprise Unlimited License

What do these Services Offer an Organization?

• Cloud computing will lead to increase in the following categories:

– Virtualization

– Usability

– Standardization

Scalability

Cloud Computing Usage

• Cloud Computing has 3 major uses:

– Infrastructure as a Service

– Platform as a Service

– Software as a Service

Infrastructure as a Service

• Defined as delivery of computer infrastructure as a service

– Fully outsourced service so businesses do not have to purchase servers, software or

equipment

• Infrastructure providers can dynamically allocate resources for service providers

– Service providers offer this service to end users

– Allows cost savings for the service providers, since they do not need to operate their own

datacenter

– Ad hoc systems allow quick customization to consumer demands

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

Software as a Service

• Defined as service-on-demand, where a provider will license software tailored

• Infrastructure providers can allow customers’ to run applications off their infrastructure, but

transparent to the end user

– Customers can utilize greater computing power while saving on the following

– Cost

– Space

– Power Consumption

– Facility
