IaaS, PaaS, and SaaS are three different cloud computing service models.

IaaS (Infrastructure as a Service) provides access to computing resources like virtual machines, storage, and networking infrastructure to users on a pay-per-use basis. Users can run their own applications on these resources.

PaaS (Platform as a Service) is a cloud computing service model that provides users with a platform to develop, test, and deploy applications without the need for them to manage the underlying infrastructure. PaaS providers take care of the underlying infrastructure and provide users with tools and services for application development.

SaaS (Software as a Service) is a cloud computing service model that provides users with access to software applications on a pay-per-use basis. Users don't need to install or manage the software themselves, as the software is hosted and managed by the SaaS provider. Examples of SaaS include email services like Gmail, and productivity suites like Microsoft Office 365.
