Name two types of cloud service models.

The correct answer identifies two prominent cloud service models: Infrastructure as a Service (IaaS) and Software as a Service (SaaS).

IaaS refers to the provision of virtualized computing resources over the internet. This model allows users to rent IT infrastructure—servers, storage, and networking—on a pay-as-you-go basis. This flexibility lets organizations scale resources based on demand without needing to invest in physical hardware.

On the other hand, SaaS delivers software applications over the internet, allowing users to access them via a web browser without the need to install or maintain the software on individual devices. This model provides significant advantages, such as automatic updates, accessibility from various devices, and reduced software management burdens.

Together, these models illustrate the diversity of cloud services, catering to different needs within the computing environment—ranging from infrastructure management to application usage.
