Actually "cloud" can be traced to relatively old ideas like utility computing. It just was not very feasible back then. EDIT: "If computers of the kind I have advocated become the computers of the future, then computing may someday be organized as a public utility just as the telephone system is a public utility... The computer utility could become the basis of a new and important industry." (John McCarthy, 1961)
