IaaS (Infrastructure as a Service) provides maximum control and requires technical expertise, with examples including AWS and Google Cloud. PaaS (Platform as a Service) offers a development environment with pre-configured infrastructure for building applications, exemplified by Google App Engine. SaaS (Software as a Service) delivers ready-made applications accessible over the internet, with examples like Gmail and Salesforce.

6. PaaS (Platform as a Service)
It refers to cloud-based platform services that provide developers with
a framework they can use to build custom applications upon.
Platform as a service (PaaS) goes a stage further and includes the

Other Examples Are;
✔ Heroku
✔ Apprenda
✔ Red Hat OpenShift
