2. What is a Cloud?
Cloud Computing by Abhijeet Singh 2
• Cloud refers to a network over the internet. It
derives its name from the time clouds were
used to represent telephone networks and the
internet in computer networks later on.
• Clouds often appear as single points of access
for consumers' computing needs. This causes
centralization of data and gives mobility and
versatility to the users of cloud services.

3. Why use the cloud?
• Using cloud computing has multiple benefits
such as automated backups, multiple and
simultaneous data access and unmatched data
portability all combined over a steep
reduction in server and storage costs.

4. What is Cloud Computing?
• Cloud computing is network based computing
where shared resources software and
information are shared among multiple users.
• Cloud computing allows a user to consume
the resources without investing in the basic
infrastructure such as software licensing,
Server procuring and maintenance costs.
• It is like Gmail, use when you want and where
you want.

5. Understanding Cloud Computing
• Client consists of
computer hardware or
software.
• Application
/Platform/Infrastructure
(As the case may be)
• Server refer to the
hardware or software
designed specifically for
delivery in the cloud.
Cloud Computing by Abhijeet Singh 5

6. Why Cloud computing?
• There is only one versatile application provided
by the provider which in turn saves the cost for
both the provider and the consumer.
• The users pays only for the services they use(Such as
Electricity) or on a timely basis(Such as club membership). This gives
cloud computing an advantages as the user pays
for only for what he uses and hence allows to
save huge costs for the consumer.

7. What services are available in the
market?
• Cloud Operating Systems
• Online Storage
• Online office suites
• Cloud hosting
• Online sales management over the cloud
• Online CRM
• Cloud collaboration
• Online app development
• Email Services
• Instant messaging services

8. Applications in business
• Small and Medium Enterprises(SMEs) are
getting increasingly associated with Cloud
Computing as they cannot justify or afford the
large capital expenditure of IT.
• SMEs in emerging market can be benefited by
established infrastructure of provider and
inexpensive models of management.

9. Kinds of Cloud Computing
• Software As a Service.(SaaS)
• Platform As a service.(PaaS)
• Infrastructure As a service (IaaS)
• Software as a Service(SaaS) is providing all the
features of a sophisticated software, but through
a browser , not a locally installed application.
SaaS eliminates worries about app servers,
storage, application development and related,
common concerns of IT. The best examples are
Salesforce.com, Google’s Docs
Cloud Computing by Abhijeet Singh 9

10. Kinds of Cloud Computing
• Platform As a service(PaaS) is about providing
virtualized servers and allowing users to run and
develop applications on them without having to
worry about maintaining the operating system
and processing capabilities. Examples Microsoft
Azure & Salesforce’s Force.com
• Infrastructure As a service (IaaS) aims to replace
the need of a data centre. It provides cluster of
networks, storages, and servers . Example
Amazon’s Elastic Compute Cloud [EC2].

11. How is service provided and payment
made?
• Services are provided by the extensive use of
internet and networking. The user subscribes
only to the services which he needs. Whenever
the user needs to change the quantum of
services he can request the service provider to
provoke or revoke a particular service.
• Payment is usually made on a pay as you use
basis i.e. either on utility basis or on a timely
basis. That is the user need not to pay for the
processing capability which he doesn’t need.

12. Who are the providers?
• Providers of Cloud Computing services
Cloud Computing by Abhijeet Singh 12
IaaS
• Windows live-
Skydrive
• Amazon EC2
• Chatter
PaaS
•Microsoft Azure
•Salesforce’s
Force.com
•eyeOS’s web
app development
SaaS
• Google Docs
and Gmail
• VoIP services
from Skype
• IM service from
AOL

13. Database Storage Service
• Cloud storage is a
model of networked
online storage where
data is stored in
virtualized pools of
storage which are
generally hosted by
third parties.
Cloud Computing by Abhijeet Singh 13

14. Properties of Cloud Storage
• Cloud storage is:
• made up of many distributed resources, but
still acts as one
• highly fault tolerant through redundancy and
distribution of data
• highly durable through the creation of
versioned copies
• typically eventually consistent with regard to
data replicas

17. Features in Cloud Computing
• Cost Saving Both for the service provider and consumer deploying the
cloud is a profitable issue.
• Security Because of centralization providers are able to use security features
that many users are not able to afford.
• Metering means the usage is measureable on a per client or per user basis.
• Multi tenancy enables sharing of resources and costs across a large
pool of users. Peak-load capacity increases
• Device and location independence enable users to
access systems using a web browser regardless of their location or what device
they are using (e.g., PC, mobile)
Cloud Computing by Abhijeet Singh 17

18. Issues in Cloud Computing
• Privacy privacy over the cloud may be compromised as the data crucial to
the organization is stored outside the organization
• Compliance users may have to adopt community or hybrid deployment
modes which are typically more expensive and may offer restricted benefits.
• Adaptability as there is a single app provided by the provider it may
not be perfectly suitable for the consumer’s need.
• Connectivity poor connectivity to the provider may lead to inefficiency
on the end of consumer.
Cloud Computing by Abhijeet Singh 18

19. Cloud Implementation
• The cloud as a new and developing technology
has unlimited potential.
• The development of cloud OS such as Azure
and Chromium have heralded a new era of
networking and multitasking.
• Implementing cloud in the organization saves
precious profits.
Cloud Computing by Abhijeet Singh 19

20. Cloud in education
• Networked institutions such as universities
can create vast repositiries of knowledge that
can be accessed over the cloud.
• OPAC has been implemented in vaious
universities around the globe including DAVV.
Cloud Computing by Abhijeet Singh 20

21. Cost saving by Cloud
• Every year services such as Smartcloud by IBM
save thousands of rupees.
• Cloud delivers secure and scalable hosted IT
infrastructure with on-demand access to
virtual server and storage resources. Well
suited for development and test activities, as
well as other dynamic workloads.
