# Cloud |  | **Cloud Computing** is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each of which is a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a pay-as-you-go model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users. | |-|-| | | wikipedia:: [Cloud computing](https://en.wikipedia.org/wiki/Cloud_computing) | > “There is no cloud.
