LINUX ADMINISTRATION
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[clarification needed] and economies of scale, typically using a "pay-as-you-go" model which can
help in reducing capital expenses but may also lead to unexpected operating expenses for unaware users.
