3.  INTRODUCTION
• Cloud computing was popularized with Amazon.com releasing its Elastic Compute Cloud product
in 2006.
• CLOUD COMPUTING appeared as early as 1996, with the first known mention in
a Compaq internal document.
• The cloud symbol was used to represent networks of computing equipment in the
original ARPANET by as early as 1977.
• The word cloud was used as a metaphor for the Internet and a standardized cloud-like shape was
used to denote a network on telephony schematics

4.  TYPES OF COMPUTING
Grid computing
Fog computing
Mainframe computer
Utility computing
Peer-to-peer
Green computing
Cloud sandbox

5.  KEY CHARACTERISTICS OF CLOUD
Device and location independence
Maintenance
 Multitenancy
 Performance
 Productivity
 Security
 Resource pooling

6.  SERVICE MODELS
Infrastructure as a service (IaaS)
Platform as a service (PaaS)
Software as a service (SaaS)

7.  TYPES OF CLOUD
PRIVATE CLOUD:
Private cloud is cloud infrastructure operated solely for a single organization, whether
managed internally or by a third party, and hosted either internally or externally
 PUBLIC CLOUD:
A cloud is called a "public cloud" when the services are rendered over a network that is
open for public use. Public cloud services may be free
 HYBRID CLOUD:
This cloud is a composition of a public cloud and a private environment, such as a private
cloud or on premise resources, that remain distinct entities but are bound together, offering the
benefits of multiple deployment models

8.  APPLICATIONS
Dropbox, Facebook, Gmail
Banking, Financial Services
Health Care
Education
Government
Big data Analytics
Communication
Business Process
Finding a way on the map

9.  ADVANTAGES
Cost Savings.
High Speed.
Back-up and restore data.
Automatic Software Integration.
Reliability.
Mobility.
Unlimited storage capacity.

10.  DISADVANTAGES
Network Connection Dependency.
Limited Features.
Loss of Control.
Security.
Technical Issues.

11.  CONCLUSION
• The popularity of cloud computing is grooming day by day due to its numerous benefits.
• They are internet based Cloud resources are available over the network anytime and are accessed
through a standard mechanism that promotes use by different types of platforms .
• They also help in e-learning by providing many services online for education. Cloud computing
allows focusing more on business, not on data centers.
