What is cloud computing defined as?

Cloud computing is defined as a model that enables on-demand network access to a shared pool of configurable computing resources, including networks, servers, storage, applications, and services. This definition emphasizes the essential characteristics of cloud computing, such as on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

The core of cloud computing lies in its ability to provide resources over a network in a way that is scalable and flexible. Users can access and utilize resources as needed without the complexities of maintaining physical hardware or local installations. This on-demand capability is vital for businesses to quickly adapt to changing needs, increasing efficiency and reducing costs.

The other choices, while related to various aspects of computing, do not capture the full essence of what cloud computing entails. For instance, providing software applications over the Internet is a component of cloud services but doesn't encompass the broader concept of resource sharing and accessibility that defines cloud computing. Hosting data locally contrasts with the cloud model, which aims to shift data management to remote servers for accessibility and collaboration. Finally, though network management is a critical component of cloud services, requiring constant management doesn't adequately describe the inherent capabilities and advantages offered by cloud computing, such as scalability and ease of use.
