When you store your photos online instead of on your home computer, or use webmail or a social networking site, you are using a “cloud computing” service. Cloud computing refers to the delivery of computing resources over the Internet instead of keeping data on your own hard drive or updating applications for your needs, at another location, to store your information or use its applications. The cloud computing model allows access to information and computer resources from anywhere that a network connection is available. Cloud computing provides a shared pool of resources, including data storage space, networks, computer processing power, and specialized corporate and user applications.

Characteristics of Cloud Computing:

On-demand self-service: Customers can request and manage their own computing resources.

Broad network access: Allows services to be offered over the Internet or private networks.

Resource pooling: Customers draw from a pool of computing resources, usually in remote data centers.

Rapid elasticity: Services can be scaled larger or smaller.

Measured service: Use of a service is measured and customers are billed accordingly.

Cloud Storage:

With a cloud storage service, you can be sure that you never lose important files such as work documents, family photos, your favorite music and anything else you care about on your computer. Like with online backup, if your hard drive crashes, your computer is stolen, you accidentally erase important information from your computer or you otherwise lose access to important files, cloud storage services give you the ability to quickly restore any lost information.

Cloud storage is especially useful for people who work on many different devices. These services sync your files across all of your computers, or even phone, to make sure that you have the most up-to-date information and version of the file available no matter where you are. You can even collaborate on files and share them with others, with each person able to see changes in real-time!

Advantage and Disadvantage of Cloud Storage:


It’s cheap, doesn’t require installation, doesn’t need replacing, has backup and recovery systems, has no physical presence, requires no environmental conditions, requires no personnel and doesn’t require energy for power or cooling.


While consumers are used to slow internet downloads, they aren’t accustomed to waiting long periods of time for a document or spreadsheet to load.
