4. What is Cloud Computing?Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet.

5. In other words, this is a collection/group of integrated and networked hardware, software and Internet infrastructure.

6. Using the Internet for communication and transport provides hardware, software and networking services to clients.

7. These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very simple graphical interface or API (Applications Programming Interface).

8. Simply a metaphor for the internet8/14/20104

9. 8/14/20105The hardware and software services are available to the general public, enterprises, corporations and businesses markets.

10. Cloud computing is an umbrella term used to refer to Internet based development and services.

11. Remotely hosted: Services or data are hosted on remote infrastructure.

12. Services or data are available from anywhere.History of Cloud ComputingThe underlying concept dates back to 1960’s“Computation may someday be organized as a public utility ” -John McCarthyThe term ‘Cloud’ into commercial use in the early 1990’s

13. General Magic launched a short-lived Cloud Computing product in 1995

14. Salesforce.com was established in 1999 which provided the concept of ‘On Demand’ & Saas68/14/2010

16. IBM detailed these concept in 2001

17. Amazon modernized their datacenters in 2005

18. In 2007 Google, IBM etc embarked on a large scale CC research project

19. By mid 2008 CC gained popularity in the mainstream pressMore About Cloud Computing…A paradigm

20. Information is permanently stored in servers on the internet
