SaaS (Software as a Service), IaaS (Infrastructure as a Service), and PaaS (Platform as a Service) are three primary cloud computing models.

SaaS: In this model, software applications are delivered over the internet, and users can access them through a browser or an app. Examples of SaaS include Google Apps, Salesforce, and Dropbox.

IaaS: In this model, cloud providers offer virtualized computing resources like storage, networking, and servers over the internet. Customers can use these resources to build their own cloud infrastructure. Examples of IaaS include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

PaaS: In this model, cloud providers offer a development platform for creating and deploying applications over the internet without the need for infrastructure management. Examples of PaaS include Heroku, Google App Engine, and Microsoft Azure App Service.
