Which service model primarily focuses on providing virtualized computing resources over the internet?

1. Software as a Service (SaaS)

2. Platform as a Service (PaaS)

3. Infrastructure as a Service (IaaS)

4. Container as a Service (CaaS)

The correct answer is: Infrastructure as a Service (IaaS)

The service model that primarily focuses on providing virtualized computing resources over the internet is Infrastructure as a Service (IaaS). IaaS offers raw computing resources such as virtual machines, storage, and networks, allowing users to configure and manage these resources according to their specific needs. This model gives users the flexibility to manage the operating systems, applications, and runtime environments they require, while the underlying physical infrastructure is handled by the service provider. IaaS is particularly beneficial for businesses that need scalable resources without the burden of managing physical hardware. Users can provision additional resources on demand and pay only for what they use, making it a cost-effective solution for varying workloads. In contrast, other service models serve different needs. Software as a Service (SaaS) delivers complete software solutions over the internet without users needing to manage the underlying infrastructure or platform. Platform as a Service (PaaS) provides a platform allowing developers to build, deploy, and manage applications without handling the underlying infrastructure. Container as a Service (CaaS) offers a specific way to manage and deploy containerized applications but does not primarily focus on general virtualized computing resources like IaaS does.
