👉 Cloud computing is a model for delivering information technology services where resources, such as servers, storage, databases, networking, software, and analytics, are provided over the internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale. Instead of owning and maintaining physical infrastructure, users access these services on-demand from cloud providers like Amazon Web Services, Microsoft Azure, or Google Cloud Platform. This approach allows businesses and individuals to scale their computing resources up or down based on demand, reducing capital expenditure and operational costs while increasing efficiency and agility. Cloud computing encompasses various service models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), each catering to different needs from raw computing power to fully managed applications.
