Cloud computing

Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by users. Large clouds often have functions distributed across multiple locations, each of which is a data centre. Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to provide faster innovation, flexible resources, and economies of scale. Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider's network. They don't float in cyberspace. Cloud space exists on individual servers in data centres and server farms around the world. Data centres and hosting providers provide server space for cloud computing.
