Which of the following best describes cloud computing?

Cloud computing is best described as the remote delivery of computing services over the internet. This definition captures the essential nature of cloud computing, which allows users to access a variety of resources, such as servers, storage, databases, networking, software, and analytics, from anywhere with an internet connection. The model provides flexibility, scalability, and cost-effectiveness since it eliminates the need for extensive local infrastructure and permits users to pay only for the resources they consume.

The other options do not accurately reflect the comprehensive and flexible nature of cloud computing. Storing data on local servers focuses solely on traditional storage methods, while using physical storage devices for data management implies reliance on hardware rather than leveraging the advantages of remote services. Maintaining databases only is too narrow in the scope of what cloud computing encompasses, as it involves more than just database management; it includes a wide range of IT services available via the cloud.
