A Cloud Service Provider (CSP) is a company that offers various computing services over the internet. These services can include storage, processing power, and software applications, allowing businesses and individuals to access resources without needing physical hardware. Popular examples of CSPs include Amazon Web Services, Microsoft Azure, and Google Cloud. CSPs operate on a pay-as-you-go model, meaning users only pay for the resources they consume. This flexibility helps organizations scale their operations efficiently and reduces the need for significant upfront investments in IT infrastructure. Overall, CSPs play a crucial role in modern computing by enabling easy access to powerful technology.
