Cloud computing is a transformative technology that enables the delivery of computing resources and services over the internet. Instead of relying on local servers or personal computers, users can access a vast pool of resources, including storage, processing power, and applications, hosted on remote servers. This model offers flexibility, scalability, and cost savings, allowing organizations to pay only for the resources they use. Cloud computing encompasses various service models, such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), catering to diverse needs across industries and applications.
