Explanation/Reference:
The diagram below depicts the Cloud Computing stack – it shows three distinct categories within Cloud Computing: Software as a Service, Platform as a Service and Infrastructure as a Service.
A simplified way of differentiating these flavors of Cloud Computing is as follows;
SaaS applications are designed for end-users, delivered over the web

IaaS is the hardware and software that powers it all – servers, storage, networks, operating systems
