3. INTRODUCTION
• Cloud computing is the on-demand
availability of computer system resources,
especially data storage and computing
power, without direct active management
by the user.
• Instead of using the storage space on
your phone, computer or tablet, your
information is housed in virtual servers.

4. INVENTION
• Cloud Computing was invented in the early 1960s
by J.C.R Licklider (Joseph Carl Robnett Licklider).
• He was an American Psychologist and Computer
Scientist.
• During his network research work on ARPANet
(Advanced Research Project Agency Network),
trying to connect people and data all around the
world, gave an introduction to Cloud Computing
technique which we all know today.

5. USES OF CLOUD COMPUTING
• Social Networking: The Software as a Service
(SaaS) cloud computing concept is exemplified by
platforms like Facebook, Twitter, and LinkedIn.
• Communication : People may use cloud computing
to use cloud-based methods of communication
like calendars and emails.
• Data backups and archiving: Helps in saving and
preserving of data.

7. PUBLIC CLOUDS
• Public clouds are cloud environments
typically created from IT infrastructure not
owned by the end user.
• Some of the largest public cloud providers
include Alibaba Cloud, Amazon Web
Services (AWS), Google Cloud, IBM Cloud,
and Microsoft Azure.

8. PRIVATE CLOUDS
• Private clouds are loosely defined
as cloud environments solely
dedicated to a single end user or
group, where the environment
usually runs behind that user or
group's firewall.
• All clouds become private clouds
when the underlying IT
infrastructure is dedicated to a
single customer with completely
isolated access.

9. HYBRID CLOUDS
• A hybrid cloud is a seemingly
single IT environment created
from multiple environments
connected through local area
networks (LANs), wide area
networks (WANs), virtual
private networks (VPNs),
and/or APIs.

11. DISADVANTAGES
•Internet Connectivity
•Limited Control
•Security issues
•Variation in Cost
•Lack of Supports
