What does IaaS stand for in cloud computing?

IaaS stands for Infrastructure as a Service, which is a cloud computing model that provides virtualized computing resources over the internet. In this model, organizations can rent IT infrastructure such as servers, storage, and networks from a cloud provider on a pay-as-you-go basis, instead of investing in local servers and hardware. This allows companies to scale their infrastructure quickly and efficiently based on their needs, providing greater flexibility and cost-effectiveness.

The other options encompass concepts that are either not standardized terms in cloud computing or do not accurately reflect the services delivered under the IaaS model. For instance, "Internet as a Service" is not a recognized service model and does not convey the idea of providing infrastructure resources. "Information as a Service" typically refers to software and data management solutions rather than infrastructure provisioning. "Integrated as a Service" is vague and doesn't align with established terminology in the cloud computing space. Thus, the correct interpretation of IaaS revolves around the provision of fundamental computing resources, making "Infrastructure as a Service" the accurate choice.
