Cloud computing is how data is accessed using remote servers via Internet (known as “the cloud”). Cloud computing relies on sharing hardware and software resources over a network rather than on local servers or personal devices. This network of servers and connections is collectively known as the cloud. Google Docs is an example of Cloud computing. Cloud services can be used to provide high-performance computing, as needed.
Cloud computing is an alternative for existing enterprises to offload overburdened IT infrastructures with value-added capabilities.
Cloud computing is the emerging industry buzz word driven largely by service offerings from big corporate players like Google, IBM, Amazon, Microsoft, Sun Microsystems and more.
