Which cloud model primarily focuses on providing computational resources such as storage and networking?

The selected answer, Infrastructure as a Service (IaaS), correctly identifies the cloud model that primarily emphasizes providing fundamental computational resources, including storage, networking, and processing power. IaaS is designed to offer the bare essentials that users need to build and manage their environments, allowing them to rent virtualized hardware from cloud providers. This model enables businesses to scale their infrastructure up or down according to their requirements without the need to invest in physical hardware, thus providing flexibility and cost-efficiency.

IaaS facilitates the creation of virtual machines and storage, thereby allowing users to deploy and manage their software applications while the underlying hardware and network infrastructure is managed by the cloud provider. This is particularly useful for organizations that require robust infrastructure for varying workloads while ensuring they have full control over their operating systems and applications.

Other cloud models focus on different aspects; for example, Software as a Service (SaaS) provides software applications over the internet, where users access applications hosted externally rather than managing infrastructure. Platform as a Service (PaaS) offers a platform allowing developers to create, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching apps.
