3. What is cloud computing?
Cloud computing is a type of
Internet-based computing that
provides shared computer processing
resources and data to computers and
other devices on demand.
It is a storage, a processing capacity
are accessed over the internet.

4. History :
Cloud computing is believed to have been
invented by Joseph Carl in the 1960 to
connect people and data from anywhere at
any time.
Amazon Web Services introduced their
cloud storage service in 2006, and has gained
widespread recognition and adoption as the
storage supplier such as Dropbox and
Pinterest etc.

5. Characterstics :
1. Maintenance
2. Cost
3. Security
4. Performance

6. Deployment of a cloud computing
Only for one
organisation.
Highly secure
Highest
level of
efficiency.
Combination of
public and private
clouds.

7. Service models of cloud computing
The three building blocks of the cloud
computing are :
1. SAAS
2. PAAS
3. IAAS
These allows to run applications and store data
online.

8. Software as a service (SAAS):
The shelf applications are accessed
over the internet
Example : pixlr, google docs.
Advantages :
1. Free or paid via subscription.
2. Accessible from any computer.

9. Platform as a service(PAAS):
 Provides environment and tools for
creating new online applications.
Example : google app engine.
Advantages :
1. Rapid development.
2. It is a private or public deployment.

10. Infrastructure as a service(IAAS):
 It provides physical devices (servers)
Example: amazon web services.
Advantages :
1. Very customizable.
2. Easy to migrate than PAAS.

11. Cyclic process of cloud computing:

12. Cloud components :
Ex: Mobile (android , iphone)
Ex : google ,maps , alexa
Ex: web apps (facebook)
Ex :Google app engine
Ex: database
Ex: skytap

13. Advantages :
Immediate upgrades put new features
into worker’s hand to make them more
productive.
The costs are much more flexible.
The connection is always on and as
long as workers have an internet
connection.

14. Disadvantages :
Security and privacy in the cloud for
companies
Dependency and risk in vendor lock-in.
Increased vulnerability.
Many IAAS service fall short because
most business applications are difficult
to fit in to it.

15. Conclusion :
Cloud computing is a really cheap way
for companies to have all the
resources they need in once place.
It’s a much better way to spread your
resources, and it becomes easier to
access things from longer distances.
