What is the definition of cloud computing?

The definition of cloud computing is best captured by a model for enabling convenient network access to a shared pool of configurable resources. This definition highlights key characteristics of cloud computing, including on-demand access, scalability, and resource pooling. It emphasizes the ability of users to access computing resources such as servers, storage, and applications over the internet, making it flexible and cost-effective.

The focus on "shared pool of configurable resources" indicates that cloud computing allows for dynamic resource allocation and efficient resource management, meeting the varying needs of users without the need for physical on-site infrastructure. This model supports a variety of service types, from Infrastructure as a Service (IaaS) to Software as a Service (SaaS), thus underscoring its versatility and applicability across different computing needs.

In contrast, other options provided do not encompass the full scope of cloud computing. Describing it solely as a service model for off-site data storage simplifies its capabilities; cloud computing is much broader than just data storage. Similarly, labeling it as a complex IT infrastructure management approach overlooks the accessibility and convenience that cloud computing provides. Lastly, defining it as a platform for hosting network security solutions is too narrow and does not reflect the primary function of cloud computing, which is to deliver a
