Cloud computing refers to storing and accessing data and programs over the Internet instead of a computer's hard drive. It provides advantages such as cost efficiency since users only pay for resources used, elasticity in capacity as users can increase storage and computing power as needed, reliability through redundancies to prevent data loss, and device/location independence allowing access from any Internet-connected device. Key benefits include pay-as-you-go pricing, scalability, robust security protections, and the ability to access files and run programs from any location.

2. Adventages of cloud computing

6. 1. What is “Cloud Computing”
 Comes from the early days of the Internet where
we drew the network as a cloud… we didn’t care
where the messages went… the cloud hid it from
us”
– Kevin Marks, Google
 Storing and accessing data and programs over the
Internet instead of your computer's hard drive.
-Eric Griffith,PC Magazine

8. 2.Advantages of cloud computing
i. Cost-efficiency
ii. Elasticity in capacity(Pay as much as you use)
iii. Reliability
iv. Device and location independence

9. i.) Cost Efficient
Balance between performance and cost

10. ii.)Elastic Capacity
 Pay as much as you use
 Increase capacity as much as you want

11. iii.) Reliability
 Having control on machines to reach data
 Fire resistant walls and doors
 7x24 security
 Precautions for natural diseasters

13. iv.)Device and location independence
 On any device which can connect to the internet
 Just by entering e-mail adress and password

15. Conclusion
 “Why are we buying more boxes? Why do we need
more software for cloud computing? ……The cloud is
not a box. It just isn’t. There are no apps marketplaces
if your cloud is a box.”
Marc Benioff, CEO – Salesforce.com
