While Gartner estimated that the global public cloud services end-user spending forecast to reach $600 billion by 2023. Market Īccording to IDC, the global spending on cloud computing services has reached $706 billion and expected to reach $1.3 trillion by 2025. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand, providing burst computing capability: high computing power at certain periods of peak demand. Value proposition Īdvocates of public and hybrid clouds claim that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs. 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. Large clouds often have functions distributed over multiple locations, each of which is a data center.
Cloud computing metaphor: the group of networked elements providing services need not be individually addressed or managed by users instead, the entire provider-managed suite of hardware and software can be thought of as an amorphous cloud.Ĭloud 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.
