What is cloud computing ?
“Any Situation In Which Computing Is Done In A Remote Location (out in the clouds) Rather than on your desktop or portable Device.”
Cloud Computing
Low Cost For User And Providers. Independence Of Device And Software. Efficient Utilization Of all the resources. Ability to continusly add new users and
applications . Data is secure with policies to protect its security
What is Cloud Computing

Amazon web serviceSeveral large Web companies are nowexploiting the fact that they have data storage
capacity that can be hired out to others. Amazon is one of the foremost and most reputed Cloud Computing service provider,Which includes:Simple Storage Service (S3)
Elastic Compute Cloud (EC2) SimpleDB
Advantages1. Lower computer costs2. Improved performance3. Reduced software cost4. Instant software updates5. Affordable6. Unlimited storage capacity7. Increased data reliability8. Universal document access9. Latest version availability10. Device independance
Disadvantage
1. Requires a constant Internet connection2. Does not work well with low-speed
connections3. Features might be limited4. Can be slow5. Stored data might not be secure6. Stored data can be lost7. Harder to know who can alter the data and
where they come from.
conclusion
Thus cloud computing provide a super-computing power.This cloud of computer extends beyond a single computer or enterprise.
In Future The Security and Reliability shall Be Improved By the Introduction of certain globally accepted standard.
