Which model provides hardware resources for cloud applications?

Infrastructure as a Service (IaaS) is the model that provides hardware resources for cloud applications. In IaaS, cloud service providers offer virtualized computing resources over the internet, including physical servers, storage, and networking capabilities. This allows organizations to rent IT infrastructure on a pay-as-you-go basis rather than investing in and maintaining their own physical hardware.

IaaS gives users the flexibility to scale resources up or down as needed, enabling them to respond quickly to changing workloads and requirements. Additionally, it provides a high level of control over the infrastructure, allowing users to install and manage their operating systems and applications as they see fit. This is particularly beneficial for companies that need to quickly deploy applications without the overhead of hardware procurement and setup.

In contrast, other models such as Software as a Service (SaaS) and Platform as a Service (PaaS) do not primarily focus on providing hardware resources; instead, SaaS delivers software applications over the internet, and PaaS provides a platform allowing developers to build, deploy, and manage applications without worrying about the underlying hardware. Function as a Service (FaaS) further abstracts these elements, allowing users to execute code in response to events without managing servers. Thus,
