How can cloud computing be best described?

Cloud computing is best described as a set of virtualized IT functions abstracted from hardware because this definition captures the essence of cloud computing. It emphasizes the virtualization aspect, whereby resources such as storage, processing power, and applications are provided over the internet and can be accessed on demand, independent of the underlying hardware.

By abstracting IT functions from physical hardware, cloud computing allows for greater flexibility, scalability, and resource management. Users can provision resources as needed, without the constraints of physical servers or infrastructure, enabling organizations to optimize their IT operations and cost structures.

This definition aligns with key characteristics of cloud computing, such as multi-tenancy, self-service provisioning, and on-demand access, which are integral to modern cloud services.
