Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics and more over the Internet ("the cloud") to offer faster innovation, flexible resources and economies of scale. It allows users to access applications from anywhere with an Internet connection rather than installing them on a local computer. The advantages of cloud computing include scalability, ubiquitous network access, increased data security and backup, and cost reductions. However, it also relies on an Internet connection, has compatibility issues with some devices, and users have less control over and visibility of the physical server locations.
