"Cloud computing" refers to the delivery of computing services—such as servers, storage, databases, networking, software, and analytics—over the Internet. It allows users to access and utilize resources on-demand, without the need for local infrastructure or physical hardware. Cloud computing offers scalability, flexibility, and cost-efficiency, as users only pay for what they use. It encompasses various models, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), catering to diverse business needs.
