Which of the following best describes the concept of Cloud Computing?

The concept of Cloud Computing is best described as access to shared resources over the internet. This definition highlights the fundamental nature of cloud services, which provide users with on-demand access to a variety of computing resources such as storage, processing power, and applications, all located on remote servers that can be accessed via the internet.

In cloud computing, users typically do not need to worry about the underlying hardware or infrastructure, as these are managed by cloud service providers. This model allows for greater scalability and flexibility, enabling users to scale resources up or down as needed, pay for only what they use, and access services from anywhere with an internet connection.

The other options do not encapsulate the essence of cloud computing. Having a dedicated physical server for each user suggests a more traditional and less flexible IT infrastructure model. Local servers storing user data do not utilize the scalability and accessibility offered by cloud resources. Lastly, defining cloud computing as a method of coding without external resources overlooks the connectivity and resource-sharing component central to cloud services. Understanding cloud computing as shared internet resources provides clarity on how modern computing environments function and meet user needs efficiently.
