What is cloud computing, in simple terms?
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale.From the days when use of internet started becoming popular, the network architecture diagrams show internet as cloud to hide the complexities from the end-user – hence the name cloud computing. The applications/ software are provided as services which reside in data centers with server farms and redundant storage. End-users can access them via web browsers in laptops or hand-held devices. Google Apps, Facebook and salesforce.com are examples of cloud computing which are becoming very popular especially with the younger generations. A very basic example of cloud computing is a web-based email service like Gmail where the complexity of storage and presentation of user data is provided by a third party, and users are leveraging them by means of web browsers(Nelson, 2009, para. 12).
