CAN BE USED FOR PROVIDING LIBRARY
SERVICES.
• 3. PROS AND CONS OF CLOUD COMPUTING.

4. HISTORY
1.Concept evolved in 1950(IBM) called
RJE(remote job entry processes)
2.In 2006 amazon provided first public
cloud AWS(amazon web services)

5. What is cloud computing?
“The practice of using a network of remote servers
hosted on the Internet to store, manage, and process
data, rather than a local server or a personal computer”

6. Agenda
THE WHAT: Understanding
Cloud Computing
THE WHY: Appreciating
Cloud Computing
THE HOW: Applying Cloud
Computing

7. CHARACTERSTICS
• INFRASTUCTURE
• PROVISIONING
• NETWORK ACCESS
• MANAGED METERING

8. SHARED INFRASTUCTURE
a).Uses a virtualised software model.
b).Enables sharing of physical services and
storage.
c).cloud infrastructure seeks most availability
across number of users.

9. DYNAMIC PROVISIONING
a).allows for provisioning of services
based on current demand
requirements
b).enables contraction of services
capability
c).this is done using high levels of
reliability and security

10. NETWORK ACCESS
a).Accessed across the internet from a
broad range of devices such as PC’s,
laptops and mobile services.
b).standard-based APIs are used(HTTP)
c).deployment of services in the cloud
including business application and new
application is used.

11. MANAGED METERNG
a)For managing and optimising the
service .
b)Provide reporting and billing
information
c)Consumers are billed for services
according to how much they have
actually used during the billing
period.

12. ARCHITECTURE
1.Cloud architecture
• the systems architecture
of the software systems involved in the delivery
of cloud computing, involves multiple
cloud components communicating with each
other over a loose coupling mechanism (messagi
ng queue).
• Elastic provision implies
intelligence in the use of tight or loose coupling
as applied to mechanisms such as these and
others.

13. 2.cloud engineering
• application of
engineering disciplines to cloud computing
brings a systematic approach to the high level
concerns of commercialization, standardization, a
nd governance in developing, operating
and maintaining cloud computing systems.
• It is a multidisciplinary method encompassing co
ntributions
from diverse areas such as systems, software, we
b, performance, information, security, platform, ri
sk, and quality engineering

14. SERVICE MODELS
• Software as a Service (SaaS)
– Access to resources and applications
• Platform as a Service (PaaS)
– Access to development and
operational components
• Infrastructure as a Service (IaaS)
– Completely outsources needed
storage and resources

15. Software as a Service (SaaS)
End user application is delivered as a service. Platform
and infrastructure is abstracted, and can deployed and
managed with less effort.
Platform as a Service (PaaS)
Application platform onto which custom applications and
services can be deployed. Can be built and deployed
more inexpensively, although services need to be
supported and managed.
Infrastructure as a Service (IaaS)
Physical infrastructure is abstracted to provide
computing, storage, and networking as a service,
avoiding the expense and need for dedicated systems.

16. Clouds classification
• Public cloud
• Private cloud
• Hybrid cloud
• Community
cloud

17. • • Public Cloud — The cloud infrastructure is
available to the public on a commercial basis
by a cloud service provider. This enables a
consumer to develop and deploy a service in
the cloud with very little financial outlay
compared to the capital expenditure
requirements normally associated with other
deployment options

18. • Private Cloud — The cloud infrastructure has
been deployed, and is maintained and
operated for a specific organization. The
operation may be in-house or with a third
party on the premises whether managed
internally or by a third party, and
hosted either internally or externally

19. • Hybrid Cloud — The cloud infrastructure
consists of a number of clouds of any type,
but the clouds have the ability through their
interfaces to allow data and/or applications to
be moved from one cloud to another. This can
be a combination of private and public clouds
that support the requirement to retain some
data in an organization, and also the need to
offer services in the cloud.

20. • Community Cloud — The cloud
infrastructure is shared among a number of
organizations with similar interests and
requirements. This may help limit the
capital expenditure costs for its
establishment as the costs are shared
among the organizations. The operation
may be in-house or with a third party on
the premises.

21. CLOUD COMPONENTS
• Client components: devices that end user interact
with cloud(mobile, thick and thin).
• Datacentres: collection of servers where
application is placed and is accessed via internet.
• Distributed servers: often servers are in
geographically different places, but servers acts
as if they are workers next to each other.

23. The WHY: Why are so many companies
moving to the cloud?

24. DATA,INTERNET AND THE CLOUD
Data Internet
The
Cloud
• Instead of storing data on individual physical machines,
data is stored on the Internet.
• Cloud can be Public, Private, Community, or Hybrid.

25. CLOUD SERVICES
Many companies are delivering services from
the cloud. Some notable examples as of 2010
are:
-GOOGLE: has private cloud
-MICROSOFT:
-SALESFORCE.COM:

27. Issues with Cloud Computing:
Security and Privacy
• Does the cloud back up your data?
• Is your data always safe?
• Can you conduct business abroad?
• Who is given access to your data?
• Who else is on your server?

28. Issues with Cloud Computing: Security
and Privacy Solutions
• Triage, Secure, and Back Up
• Authentication & Authorization
• “Private Cloud” vs. “Public Cloud”
• Hybrid Approach

29. Issues with Cloud Computing:
Reliability
• Past Outages
– Amazon’s “Simple Storage
Service” and “Elastic
Computing Cloud”
– Microsoft & Google
• Prevention & Strategic
Response
– Choice of server
– Think ahead
– Hybrid Approach

30. Issues with Cloud Computing:
Downsizing Workforces?
• Increasing need for
cloud experts and third-
party companies
• Increase in workforce
leads to increase in
efficiency

31. CLOUD ECONOMICS
Estimates vary widely on possible cost
savings
• “If you move your data centre to a cloud
provider, it will cost a tenth of the cost.” –
Brian Gammage, Gartner Fellow
• Use of cloud applications can reduce
costs from 50% to 90% - CTO of
Washington D.C.
• Avoid capital expenditure
-Billed on utility and subscription
-Can terminate contract any time

32. Core objectives and principles that cloud
computing must meet to be successful:
– Security
– Scalability
– Availability
– Performance
– Cost-effective
– Acquire resources on demand
– Release resources when no longer needed
– Pay for what you use
– Leverage others’ core competencies
– Turn fixed cost into variable cost

33. Benefits of Cloud Computing
• Access data anywhere, anytime through standard
internet connectionAvailability
• Pay as you go model
• Savings on maintenance, repairs, and upgrades
Cost
reductions
• Can access data and application from various devices
• Connecting employees, partners, and suppliers
globally
Mobility
• Users have access to resources that scale quickly
based on their demandScalability

34. Core Advantages
 Cost saving: You pay for what you use.
 Easy on installation and maintenance.
 Increased storage.
 Highly automated.
 Flexibility.
 Better mobility.
 Shared resources.
 Back up and restoration.
 Reduces wastes
 global warming(go cloud ! Go green!).

35. DOES CLOUD OMPUTING REDUCES
WASTES?
• Green IT cloud computing
• Cloud computing is eco-friendly
• IAAS helps in reducing e-waste
• Accelerates green IT
• Reduces global warming too

36.  Data security and privacy.
 Network connectivity and bandwidth.
 Service unavailability due to power outage.
 Dependence on outside agencies.
 Limited flexibility.
 Cost.
 Knowledge and integration.
 Long term stability of service provider.
Disadvantages

37.  Cloud Computing is in a period of strong growth, but this
technology is still has some issues of security and
somewhat it is immature. Government Technology
Research Alliance (GTRA) research showed that the most
common concern about implementing Cloud Computing
technology was security.
 The real value of cloud computing is that it makes your
library related software and data available transparently
and everywhere including in latest available smart phone
devices.
 We are all aware, country like India faced problems like
digital divide and off course very low internet bandwidth.
So, benefit of new technology can be reached to limited
area of educational area.

40. THOUGHTS ON CLOUD COMPUTING
“Companies that don’t
understand the risk just
shouldn’t use cloud
computing, the potential for a
security breach or a
compliance violation can be
high” –IDC Analyst Phil
Hochmuth
