1. Cloud computing
-An overview

2. Outline
 Cloud computing
 Cloud services-SaaS, PaaS, IaaS
 Types of clouds
 Advantages
 Disadvantages
 Conclusion

3. A Cloud depicts the Internet in computer network as an abstraction of the
underlying infrastructure it represents

5. Definition of cloud computing:
Collaboration and sharing of resources.
Cloud computing is the Style of computing which must
cater to the following computing needs:
Dynamism
Abstraction
Resource sharing

6. Cloud services:
1. Software as a Service (SaaS):
 A single instance of the service runs on the
cloud & multiple end users
 Today SaaS is offered by companies
such as Google, Salesforce, Microsoft, Zoho, etc

7. Cloud TV

8. 2. Platform as a Service (Paas):
 development environment is encapsulated &
offered as a service
offer a predefined combination of OS and
application servers, such as LAMP platform

9. Platform as a Service

10. 3. Infrastructure as a Service (Iaas):
provides basic storage and computing capabilities
Everything is done through Virtualization
The customer would typically deploy his own
software on the infrastructure

11. Infrastructure as a Service

12. Types Of Clouds:

13. SECURITY (DATA TRANSPIRANCY)

14. Advantages:
Reduce Runtime and Response time
Minimize Infrastructure Risk
Reduced cost
Multi-tenancy
UNLIMITED STORAGE
ECONOMICAL

15. DISADVANTAGES OF CLOUD
COMPUTING:
TOTALLY INTERNET CONNECTION
ORIENTED
REQUIRE HIGH BANDWIDTH OF
NET CONNECTION
VENDOR DEPENDANC FOR DATA
MAINTENANCE

16. HIGH BUDGET TO ESTABLISH
CLOUD
COMPUTING ENVIRONMENT
NOT ACCESSIBLE BY EVERYONE
HUGE POWER IS REQUIRED

17. Conclusion:
Aims to provide a means of
understanding the model and
exploring options
available for complementing your
technology and infrastructure
needs
