Which of the following is NOT a common feature of Cloud Computing?

The choice that describes a feature that is not common in cloud computing is delivering software directly on physical servers. Cloud computing fundamentally relies on virtualized resources and services rather than direct installation on physical hardware. This model allows users to access resources via the internet on-demand and scale services as needed, typically leveraging a network of servers that provide shared resources.

On-demand self-service, broad network access, and resource pooling are all key characteristics of cloud computing. On-demand self-service enables users to provision computing capabilities as needed, often without requiring human interaction with service providers. Broad network access means that services are available over the network and accessed through standard mechanisms that promote use across a variety of devices (e.g., smartphones, tablets, laptops). Resource pooling refers to the provider's ability to serve multiple customers with a single set of physical resources, dynamically assigning and reallocating them as required.

In cloud computing, the focus is on abstracting the infrastructure and allowing users to access software and services typically hosted on virtualized platforms, rather than being tied solely to physical servers.
