What Is a Cloud Service Provider ?
A cloud service provider (CSP) is a company that delivers computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet. These services allow users to access powerful computing resources without owning or maintaining physical infrastructure.
Instead of purchasing hardware or installing software locally, customers rent cloud resources on a pay-as-you-go or subscription basis. The cloud service provider manages infrastructure, security, maintenance, updates, and scalability.
