What model provides on-demand network access to a shared pool of computing resources?

1. Cloud Computing

2. Community Cloud

3. Private Cloud

4. Hybrid Cloud

The correct answer is: Cloud Computing

The model that provides on-demand network access to a shared pool of computing resources is cloud computing. This approach is designed to ensure that users can quickly provision and release computing capabilities as needed, without requiring direct interaction with the service provider. The shared resources in cloud computing can include servers, storage, applications, and services, all accessible through the internet. Cloud computing is characterized by its scalability and flexibility, allowing organizations to increase or decrease resources based on their current requirements. This is advantageous for businesses that experience varying levels of demand, as it minimizes costs by eliminating the need to maintain excess infrastructure. Community clouds, private clouds, and hybrid clouds are variations of cloud computing but tend to be more specific in their deployment or user base. For instance, community clouds are typically shared among a specific group of organizations with common interests or regulations, private clouds are utilized by a single organization and may involve dedicated resources, and hybrid clouds combine elements from both public and private clouds but do not inherently emphasize the on-demand, shared resource model that defines cloud computing. Thus, cloud computing stands out as the model that encompasses the broader concept of on-demand, scalable resource access.
