That's the point though. Manufacturing, logistics, payroll, research, advertising, legal services, ... -- outsourcing certain functions to specialist, often (but not always) cheaper or more efficient companies is a typical business practice. The term is broadly applicable and used where ever this is the case. Since there are well-known business and organizational risks associated with outsourcing, it is conspicuous that we "migrate to the cloud" instead.
We outsourced our CRM system last year to a certain company. Or you could say we migrated it to the cloud. Either way we had to audit data policies, establish contracts with them, transfer data to them, ensure the same functionality and workflows were replicated, look at the quality and reliability of their system, assign points of contact, make redundant some roles within our company, etc... Many of the things you allude to are implied by either term.
Time-sharing and remote job entry were also reasonable back in the day. You bought time on a computer to run workloads. I don't think they fit so well with the "cloud computing" model in a modern sense technically, but I do envy them for being descriptive, logical terms that describe what is going on. We got the cloud from Google CEO Eric Schmidt who said to a conference in 2006
> What’s interesting is that there is an emergent new model. I don’t think people have really understood how big this opportunity really is. It starts with the premise that the data services and architecture should be on servers. We call it cloud computing — they should be in a “cloud” somewhere.
. . .
And so what's interesting is that the two – "cloud computing and advertising – go hand-in-hand. There is a new business model that's funding all of the software innovation to allow people to have platform choice, client choice, data architectures that are interesting, solutions that are new – and that's being driven by advertising.
