Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the Internet).
Cloud storage is a model of networked online storage where data is stored on virtualized pools of storage which are generally hosted by third parties. 200 GB of Cloud Storage free. Limited Offer! Try now Hosting companies operate large data centers; and people who require their data to be hosted buy or lease storage capacity from them and use it for their storage needs. The data center operators, in the background, virtualize the resources according to the requirements of the customer and expose them as storage pools, which the customers can themselves use to store files or data objects. Physically, the resource may span across multiple servers.
Cloud storage services may be accessed through a web service application programming interface (API), or through a Web-based user interface.

Warning! "Be aware of Cloud Storage"
People may be asking, “What the heck is the ‘cloud?’” Technically, it simply means storing digital files on someone else’s computer servers and then accessing those files via the internet.
Apple, Google and Amazon amongst other tech giants have all jumped on board with “the cloud,” a remote server network that allows users to store their data without using hard drives. However, despite the convenience of having all your files easily accessible in one place wherever you go, the drawbacks are ominous.
There are major concerns about the shift to the cloud. One such concern is security. Large internet companies that hold vast quantities of personal data come under constant attack from hackers.
Sony was recently forced to admit that cyber thieves might have taken 100 million of its customers’ records. Google also revealed recently that several Gmail accounts, including some belonging to prominent U.S. politicians, were hacked.
Internet security experts say, however, that home computers are even more vulnerable. They believe it’s arguably safer to keep files in a data center run by technology professionals.
