There are a multitude of cloud technology offerings, but at the base level it is IaaS (you manage above the virtualization layer), PaaS (You manage the Dev/Ops tools, apps/data), and SaaS (You have access to an application and maybe it's governance). New Cloud Tech/Service offerings are XaaS, DRaaS, RaaS.. It all comes down to what services and functions a "cloud" provider is making available from their servers over the internet.

truthfully, at the time I had only ever worked with hardware sales. I knew nothing really about cloud but that it was the future of tech and my current employer was starting to push cloud sales.
