This allows users to run software applications and store, edit and retrieve data over the internet from large networks of remote web servers rather than on users’ own computers. [1]
The cloud refers to remotely-hosted data centres or web servers. [2]
Rather than relying on computer products from corporate servers or desktop PCs, applications and services created in this new "cloud" are delivered over the internet and often accessed through a simple web browser, e.g., google docs. [3]
Online cloud computing offers cheaper services. [4]
Also, services depend on a fast broadband connection and a fast, efficient and secure browser. [5]
Example
If you have a Hotmail, Yahoo or Gmail e-mail account you are already using one type of cloud computing service. Similarly, social networking services such as Facebook and online photo sharing services such as Flickr rely on so-called Web 2.0 technology and cloud computing. [6]
