Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on-demand, like the electricity grid.
It is a paradigm shift following the shift from mainframe to client-server that preceded it in the early 1980s. Details are abstracted from the users who no longer have need of expertise in or control over the technology infrastructure “in the cloud” that supports them. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.
Most cloud computing infrastructure consists of reliable services delivered through data centers and built on servers. Cloud soften appear as single points of access for all consumers’ computing needs. Commercial offerings are generally expected to meet the quality of service (QoS) requirements of customers and typically offer SLAs.
