Answer: the internet is thought of as a cloud to show that most users are oblivious to what happens in the cloud. The cloud is different than saas since iaas works by connecting a source host to a destination host and can include machine to machine communications, iaas connects a client (browser) to a webserver program (server application) through the internet. Saas is a piece of software such as microsoft word, and does not connect two things necessarily like iaas does. Saas- a service is also saas, netflix uses google mail for its internal communication.
