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. The functions of a large cloud are often distributed across multiple locations, each of which is a data center. 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 costly 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 centers and server farms around the world. Data centers and hosting providers provide server space for cloud computing.
