3. History of Cloud Computing
1960 : John McCarthy’s Concept
1999 : Salesforce.com
2000 : Microsoft
2001 : IBM
“Computation may someday be organized as a public
utility."
“Pioneered the concept of delivering enterprise
applications via a simple website”
“Expanded Sass Concept through web service”
2005 : Amazon
2007 : Google and IBM
2008 : Gartner Research
“Launch of Amazon web services”
“Start researching Cloud Computing”
“Start using Cloud Computing in many organization”

4. What is Cloud computing
“Cloud computing is a style of computing
where massively scalable IT-related capabilities
are provided as a service across the Internet to
multiple external customers”

5. What is Cloud Computing?
Definitions:
“Cloud computing is a general term for
anything that involves delivering hosted services over the
internet.” – Wikipedia
“Cloud computing is Internet-based computing, whereby
shared resources, software, and information are provided
to computers and other devices on demand, like the
electricity grid.”- Wikipedia
Basically a cloud is a virtualization of resources that
manages and maintains itself.

6. 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
• The name cloud computing was
inspired by the cloud symbol
that's often used to represent the
Internet in flowcharts and
diagrams.

What is Cloud Computing?
A user experience and a business model
 Cloud computing is an emerging style of IT delivery in which applications, data, and IT
resources are rapidly provisioned (on-demand) and delivered as standardized
offerings to users over the web in a flexible pricing pay-for-usage model.
An infrastructure management and services delivery methodology
 Cloud computing is a way of managing large numbers of highly virtualized resources
such that, from a management perspective, they resemble a single large resource.
This can then be used to deliver services with elastic scaling.

16. • “A way to increase capacity or add capabilities
without investing in new infrastructure,
training new personnel, or licensing new
software ... all delivered via the Web”

18. Who do you think were the
FIRSTmajor adapters of
Cloud Computing?

20. The average internet users are
one of the first major adopters of
CLOUD COMPUTING.

21. This is how it works!

22. 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

23. Cloud Deployment Models

24. Public Cloud
• Owned and managed by service provider
• Delivers select set business process, application or
infrastructure services on a “pay per use” basis
• Highly standardized
• Limited customization options
• Accessed from "outside" the firewall

 Services provided by the enterprise data center—the private
cloud

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
 Amazon’s EC2, GoGrid, RightScale and Linode are few of the examples of
service providers.

38. 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

39. 20-Apr-13
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

51. CHARACTERISTICS:
 Application programming interface (API)
accessibility to software that enables machines to
interact with cloud software in the same way the user
interface facilitates interaction between humans and
computer
 Virtualization technology allows servers and storage
devices to be shared and utilization be increased.
Applications can be easily migrated from one physical
server to another.
 Reliability is improved if multiple redundant sites are
used, which makes well-designed cloud computing
suitable for business continuity and disaster recovery

74. Cloud Computing , Tomorrow

75. Trend of Cloud Computing
Organization start to use
– Private cloud services are run in datacenters managed by
third parties, but also in private datacenters on company
property managed by corporate IT staffs.
– Corporate IT departments will create clouds within their IT
infrastructure and lease cloud power to suppliers and
customers.
More scalable and customizable
– They’re scalable, growing and shrinking as needed. They’re
also managed centrally in a virtualized environment.
– Cloud computing vendors will make their applications more
customizable by end users. Then corporations will move
mission-critical unique applications into the cloud.

76. Trend of Cloud Computing
Cloud will be all desktop software, anyone can access
– Local applications will become passé and PCs will become
slimmer, more agile gateways to the cloud where the heavy
lifting is done.
– Business units and even individual employees will be able to
control the processing of information directly, without the
need for legions of technical specialists.
Change from data sharing to application sharing
– Cloud computing will develop effective and capable of
communicating on the Internet has the potential to
enhance the speed and stability of the
exchange (Share) from the exchange of information (Data
Share) to share in the applications (Application Share) on
the cloud environment in the future.
