This document is a presentation by Dr. Paul Miller of Cloud of Data about clouds in context. It discusses several "truths" about cloud computing, including that it is simply off-premise computing, similar to utilities like the electrical grid. It also notes that cloud computing can be cheap for elastic workloads but the cost savings are less clear for normal loads. The presentation outlines the cloud computing stack including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). It discusses opportunities cloud computing presents for higher education including virtualizing servers, using cloud platforms instead of building applications from scratch, and replacing desktop software with cloud apps.

Cloud solutions may well help
ease your pain points…
but only you know where those are for your
institution
cost? efficiency? scalability? green? self-service?

why not give that demanding research group
