Which of the following best describes cloud computing?

Cloud computing is best described as remote access to resources and services over the Internet. This definition captures the essence of cloud computing, which allows users to utilize computing resources such as servers, storage, databases, networking, software, and more through the internet, rather than relying solely on local machines or personal devices.

This model provides scalability, flexibility, and convenience since users can access these services from any device with internet connectivity, enabling collaboration and efficiency across various applications and functions. Additionally, cloud computing supports various deployment models, such as public, private, and hybrid clouds, which further facilitates diverse user needs and operational scenarios.

The other options focus on concepts that are contrary to the essence of cloud computing. Physical personal devices and local data management systems limit access to resources and functionality to specific locations and devices, negating the advantages of being able to access and manage resources from anywhere. Similarly, using a database exclusively offline misses the critical aspect of connectivity and remote access that defines cloud computing.
