2. WHAT IS CLOUD COMPUTING
• Cloud computing is a natural evolution of the
widespread adoption of virtualization, service
oriented architecture and utility computing.
Details are abstracted from consumers, who
no longer have need for expertise in, or
control over, the technology infrastructure "in
the cloud" that supports them. It typically
involves over-the-Internet provision of
dynamically scalable and often virtualized
resources.

10. VIRTUALIZATION ?
• VIRTUALIZATION is an emerging IT paradigm that
separates computing functions and technology
implementations from physical hardware.
• CLOUD COMPUTING, for example, is the virtualization
of computer programs through internet connections
rather than installing applications on every office
computer
11. LET’S TRY THIS AGAIN… WHAT IS CLOUD COMPUTING?

14. KEY FEATURES OF CLOUD COMPUTING
• Pay for what you use
• Content Resides on Server(s)
• Applications are processed by the server
• User Centric (Service on Demand)
• E-Waste
15. DEPLOYMENT MODELS
• Public Cloud
• Traditional Cloud Computing – resources are
dynamically provisioned.
• Community Cloud
• Similar Requirement to share Infrastructure
• Hybrid Cloud
• Private Cloud
16. TYPES OF CLOUD COMPUTING
• SaaS - Software as Service
• Through Web Browsers- gmail and apps
• PaaS – Platform as Service
• Virtualized servers on which customer can run
existing application or develop new- MS’s Azure
• IaaS - Infrastructure as Service
• Provides Grids, Clusters or virtualized servers,
Networks, Storage and System Softwares.- Amazon

18. FEATURES & BENEFITS OF CLOUD
• Instant Elasticity- Adopt to changing requirements
• Reliability- constant operation without disruption
• Virtualization- Hides technological complexities from
users, Multi tenancy
• Cost Reduction
• Ease of Use
20. WE ARE “VIRTUALIZING” COMPUTERS TODAY
Server Virtualization
• Servers spend a lot of the time waiting for a command
• One server box can have many “services” running on
it at the same time
Desktop Virtualization
• Use Old Desktop Computers
• Dumb Terminals or Thin Clients
24. THE CRYSTAL BALL
• ISP (Internet Service Provider) will sell more than bandwidth
• Sell processor speeds and disk storage
• Subscription-based
• Establishments will move away from the local computer
• Less need for the local processing power
• Your computing experience will be the same everywhere
• Log in gains access to all your files, resources,
applications and even the same desktop background
• The allocated resources will be the same everywhere,
based on your subscriptions/ISP
26. LOS ANGLES TIMES 9TH AUGUST 2012
• NASA uses Amazon's cloud computing in Mars landing mission
• Jet Propulsion Laboratory using the company's Amazon Web Services to
capture and store images and metadata collected from the Mars Exploration
Rover and Mars Science Laboratory missions.
• Using AWS's cloud to operate the mars.jpl.nasa.gov website, images, videos
and developments to the public quickly, without having to build and operate
the infrastructure in house
• AWS enabled JPL to construct a scalable Web infrastructure in only two to
three weeks instead of months. "With unrelenting goals to get the data out to
the public, NASA/JPL prepared to service hundreds of gigabits/second of
traffic for hundreds of thousands of concurrent viewers," Amazon said.
27. PRECAUTIONS
• Data Ownership
• Down time issues- Loss of Business
• Data residence issues
• Security issues
• Withholding taxes
• Disaster Management
