 First we need to assess our usage of our clusters and if the cloud can support that. We also need to stress that we are a small liberal arts college, primarily undergraduate, with less than 3,000 students and perhaps 450 active faculty. We do not need to do cloud computing because we're going to scale upwards to 10,000 nodes.  We also have a relatively small cluster user base (50 accounts), representing many different interests groups as opposed to one large community using a small set of tools.  First we need to assess our usage of our clusters and if the cloud can support that.
