What is IaaS, PaaS and SaaS?

The three cloud service models: rent infrastructure, use a managed platform for your code, or use complete software.

In more detail

IaaS: you manage the OS upwards (virtual machines). PaaS: you deploy code and the provider runs it. SaaS: you simply use the application.

Example

EC2 (IaaS), App Service (PaaS), Gmail (SaaS).
