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.
