| IAAS-Infrastructure As A Service As SAAS is offered to you by another company, so is Infrastructure As A Service. IAAS is simply STORAGE and the most obvious examples of this are companies that store your photographs like Flikr, and companies that stream music or films. The impact of IAAS is that you no longer have to upgrade your computers or phones as you did in the past. Instead of your phone getting full of photos, they are saved on the cloud for you. | |
| NETFLIX is a company that offers you films. They host films on their cloud and when you log in, you can STREAM the film to your computer, smart phone or smart TV.

You simply don't have the storage space to save films. |
