Cloud computing delivers on-demand computing resources (compute, storage, network, applications, services) over the internet with pay-per-use economics, elasticity, and managed operations. Core principles include virtualization, resource pooling, scalability, elasticity, multi-tenancy, measured service, and broad network access. Paradigms span service models (IaaS, PaaS, SaaS), deployment models (public, private, hybrid, community), and emerging models (serverless, edge, fog, cloud-native).
