This document discusses cloud computing and its potential application for library services. It defines cloud computing as distributed computing over the internet, providing examples like webmail. The document then outlines the history, components, service models, deployment options, benefits, applications, and challenges of cloud computing. It discusses how cloud computing enables infrastructure-independent companies and applications by providing on-demand, pay-as-you-go access to computing resources and data centers.

2. • Just make you familiar with Cloud
Computing and its Services1
• Explore Cloud Computing and
how it can be used for providing
library services

3. What is Cloud Computing?
Distributed computing on internet Or
delivery of computing service over the
internet.
Eg: Yahoo!, GMail, Hotmail-
Instead of running an e-mail program on
your computer, you log in to a Web e-mail account
remotely. The software and storage for your account
doesn't exist on your computer -- it's on the
service's computer cloud.

4. History
 Concept evolved in 1950(IBM) called RJE
(Remote Job Entry Process).
 In 2006 Amazon provided First public cloud
AWS(Amazon Web Service).

5. Cloud Components
It has three components
1.) Client computers
2.) Distributed Servers
3.) Datacenters

6. Clients
Clients are the device that the end user
interact with cloud.
three types of clients:
1.) Mobile
2.) Thick
3.) Thin (Most Popular)

7. Datacenter
It is collection of
servers where
application is
placed and is
accessed via
internet.

8. Distributed servers
Often servers are in geographically
different places, but server acts as
if they are working next to each
other.

9. Central Server
 It Administers the system such as monitoring
traffic, client demands to ensure everything
runs smoothly.
 It uses a special type of software called
Middleware.
Middleware allow computer to communicate
each other.

10. Service Models
SaaS(Software as a service): Required
software, Operating system & network is
provided.
PaaS(Platform as service): Operating
system and network is provided.
IaaS(Infrastructure as a service): just
Network is provided.

11. Deployment of Cloud
Service
Public Cloud
Private Cloud
Community Cloud
Hybrid Cloud(Combined Cloud)

12. Why cloud service is popular?
 Reduce the complexity of networks.
 Do not have to buy software licenses.
 Customization.
 Cloud providers that have specialized in a particular
area (such as e-mail) can bring advanced services
that a single company might not be able to afford
or develop.
 scalability, reliability, and efficiency.
 Info. at cloud are not easily lost.

13. Application
Social Networking sites.
E-mail sites.
Search Engines.
Many more services OVER THE INTERNET.

Challenges
 Alignment with the needs of the business / user / non-computer specialists /
community and society
 Need to address the scalability issue: large scale data, high performance
computing, automation, response time, rapid prototyping, and rapid time to
production
 Need to effectively address (i) ever shortening cycle of obsolescence, (ii)
heterogeneity and (iii) rapid changes in requirements
 Transform data from diverse sources into intelligence and deliver intelligence to
right people/user/systems
 What about providing all this in a cost-effective manner?

18. What is the purpose and benefits?
 Cloud computing enables companies and applications, which are
system infrastructure dependent, to be infrastructure-less.
 By using the Cloud infrastructure on “pay as used and on
demand”, all of us can save in capital and operational
investment!
 Clients can:
 Put their data on the platform instead of on their own desktop PCs
and/or on their own servers.
 They can put their applications on the cloud and use the servers within
the cloud to do processing and data manipulations etc.
