This video explains cloud computing's fundamental building blocks of software as a service or SaaS, platform as a service or PaaS,, and infrastructure as a service or IaaS. In effect, this video is therefore a seven minute presentation of chapter four of my handy paperback book A Brief Guide to Cloud Computing.
