2. Cloud Computing
Powerful services and applications are
being integrated and packaged on the
web in what the industry now calls
„cloud computing‟
Mr. Barack Hussain Obama

3. History Of Cloud Computing
1. Concept dating back to the 1960‟s by John McCarthy, a
computer scientiest , brought up the idea that “computataion
may someday be organized as a public utility”
2. Idea that revolutionez Cloud computing : Moving from
clustering computer to grid computing …

4. What is Cloud Computing ?
 “Cloud computing is a computing paradigm shift
where computing is moved away from personal
computers or an individual application server to a
“cloud” of computers. Users of the cloud only need
to be concerned with the computing service being
asked for, as the underlying details of how it is
achieved are hidden. This method of distributed
computing is done through pooling all computer
resources together and being managed by
software rather than a human.“

5. The “Cloud” = 10X Improvements
 Ease of Use
 Scalability
 Risk
 Reliability
 Cost
5

6. Ease of Use
 Deploy infrastructure with a mouse or API
– No cabling, screwdrivers, racking, unboxing,
buying
– Middle of the night
– Do it yourself remotely from anywhere anytime

7. Scalability
 See Ease of Use
 Control your infrastructure with your app
 Nothing to purchase and take delivery on
 Instant

8. Risk
 Nothing to buy
 Cancel immediately
 Change instantly, even operating systems
 Throw it out
 Rebuild it instantly after testing
RISK

9. Reliability
 Based on enterprise grade hardware
 Design for failures:
– Automatically spin up replacements
– Use multiple clouds

10. Cost
 “Turn off the lights” = turn off servers you
aren‟t using
– Ex: Turn off development and test
environments
 Pay for only what you use
 No need to buy in advance
 Zero Capital Outlay
 No contracts

11. Traditional Hosting Costs
Continue to Grow
 High CapEx
 Low facility asset utilization
(55%)
 High Depreciation (42-50%)
 Power/Cooling costs > Server
Costs
 Not “Green”
 30% hardware obsolescence

13. Other Definitions
“Cloud computing is an emerging approach to shared
infrastructure in which large pools of systems are
linked together to provide IT services.”
“…a hosted infrastructure model that delivers
abstracted IT resources over the Internet”
“Cloud computing describes a systems architecture.
Period. This particular architecture assumes nothing
about the physical location, internal composition or
ownership of its component parts.”

14. 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
14

15. Functionality
 Cloud computing is an emerging technology that is
revolutionizing IT infrastructure and flexibility, and
software as a service (SaaS).
 During the economic recession , there r huge cost-
reduction pressure and cloud computing shows
allows business to do just that by trapping into
cloud computing platforms on a pay as u go basis
.
 Customer retention is vital , especially today in our
indian economy .

16. What Technologies is Cloud
Computing Replacing ?
 CC is replacing larger corporate Data
Centers and unnecessary, expensive private
servers infrastructure .
 Web 2.0, SaaS , Enterprises and govt. users
are adopting CC becoz it eliminates capital
investments in hardware and facilities as
well as reduces operating labor
16

17. Companies Leading in Cloud
Computing
 Google
 Amazon
 Microsoft
17

18. Google
 “Google 101”
- Network made up of millions of cheap servers,that
wud store staggering amount of data, including numerous
copies of world wide web.
-makes search faster, helping getting out
answers to billions of queries in fractions of seconds .
 Google has invested more than $2 billion a
year in data centers for cloud computing .
 By far the leader in the technology
18

19. Amazon
 Amazon Elastic Compute Cloud “Amazon EC2”
-web service interface that provide
resizable computing facilities in a cloud
-designed to make web-scale computing
easier to developers
reduces the time required to obtain and
boot new server space from weeks to
minutes
-allows developers to pay only for the
capacity that they actually use 19

20. Cloud computing usages
 CC has 3 major use :-
-Infrastructure as a Service
-Platform as a Service
-Software as a Service
20

21. Infrastructure as a Service
 Defined as delivery of computer
infrastructure as a service
 Infrastructure providers can dynamically
allocate resources for service providers
-service provide provides this service to
end user.
-allows cost savings for the service
providers,sine they do not need to
operate their own datacentre.
-Ad hoc systems allow quick
customization to consumer demad…. 21

22. Platform as a Services
 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 customer unique
needs
22

23. Software as a Services
 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
*Customer can utilize greater computing
power while savingon the following:-
-cost
-space
-power consumption
23

24. Cloud computing Pros
 Reduced hardware equipment for end users
 Improved performance
 Lower hardware and software maintenance
 Instant software updates
 Accessibilty
 Less expensive
 Better collaboration
 Pay for wat u use
 flexible 24

25. Cloud computing Cons
 Security issues
 Internet connection
 Too many platforms
 Location of services
 Time of transition speed
25

26. Expansion
 Resourses r expected to triple by 2012, from
$16 billion $42 billion.
 Cloud computing is said to be the foundation
of the next 20 years of IT technology ….
