We start with mainframes and time sharing, then move through hypervisors, virtual machines, and the moment virtualization became the backbone of the cloud. From there, the story accelerates into public, private, hybrid, and community cloud models, and the service stack that defines modern IT—Infrastructure as a Service, Platform as a Service, and Software as a Service—so you know exa...
