Which of the following is an example of a cloud service provider?

A cloud service provider (CSP) is an organization that offers various cloud computing services such as infrastructure, platforms, or software over the internet. These services are delivered via data centers that a CSP manages and maintains.

Microsoft's Azure exemplifies a cloud service provider because it provides a range of cloud services including computing power, storage solutions, and databases, all accessible from anywhere with an internet connection. Azure allows customers to leverage scalable resources on demand, which is a hallmark of cloud computing environments.

In contrast, a local IT support company generally provides on-site or off-site support and does not deliver cloud computing services across the internet. A private data center typically refers to a physical location housing servers that an organization owns and controls, which is distinct from the public or shared resources offered by cloud services. A non-profit organization, while it could potentially use cloud services, is not inherently a provider of cloud services itself. Therefore, Azure stands out as the defining example of a cloud service provider among the given options.
