Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each location being a data center. Cloud computing relies on sharing of resources to achieve coherence and economies of scale.

The availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture and autonomic and utility computing has led to growth in cloud computing. As of 2017, 90% of the public cloud runs a Linux-based operating system.Clouds may be limited to a single organization (enterprise or private clouds), or be available to multiple organizations (public cloud).

Cloud providers typically use a "pay-as-you-go" model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for unaware users.
