Cloud computing delivers computing services—including storage, processing power, databases, and software—over the internet on a pay-as-you-go basis. It enables users to access resources from anywhere without needing local infrastructure. Major cloud models include IaaS, PaaS, and SaaS, supporting scalability and flexibility in digital services. Assertion (A): Cloud computing allows users to access computing resources on demand over the internet, reducing the need for physical hardware at the user's location. Reason (R): Cloud computing requires users to install and maintain all hardware and software locally to access cloud services.
