I am interested in a model that supports all of the above, but individual jobs have a very short lifespan (a few minutes) and are time critical (every minute counts). Also, there is not necessarily a steady stream of jobs, such that there are demand peaks (several times a day). In that model I do not want to wait minutes to provision compute nodes for a job that runs 5 minutes. Neither do I want to run a cluster permanently that has 100% utilization for maybe 2 or 3 hours in total per day. So a cloud model would be quite attractive, if it could deliver the performance, provision fast enough, and charge in minute intervals rather than hours.
