What defines cloud computing?

Cloud computing is defined primarily by delivering computing services over the internet. This definition encompasses a wide range of resources, including data storage, processing power, and various applications that users can access remotely. The fundamental characteristic of cloud computing is its reliance on the internet to provide access to these resources, allowing users to utilize computing capabilities without the need for local installations or hardware management.

This model offers flexibility and scalability, enabling users to pay for only what they use and to access their data and applications from anywhere with internet connectivity. It facilitates collaboration and resource sharing, which is a central advantage of cloud services—users can work together in real-time from different locations.

The other options refer to traditional computing practices where services are restricted to local setups rather than leveraging the flexibility and scalability offered by cloud computing. Such options do not capture the essence of how cloud computing revolutionizes access and efficiency in IT services.
