You forget about switches, routers, servers, etc. They are also part of the internet. And the "cloud" is just that: the servers you don't own and don't control. When some company mentions that they will store your data in the cloud, they could have just said that they are going to store your data on their servers. But for some reason "the cloud" sounds more trustworthy than "our servers". I maintain that "the cloud" is a marketing term, not a technical one. There is no new technology here. There is no need for the term "cloud". On the other hand, the internet was a new technology, thus the new term for it was justified.
