Cloud computing is the delivery of computing services, such as servers, storage, databases, networking, software, and analytics, over the internet ("the cloud"). This allows users to access and use these resources on-demand, without needing to own or maintain physical hardware or infrastructure. Cloud computing offers scalability, flexibility, and cost savings, as users typically pay only for the resources they consume. There are various types of cloud services, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
