Software/Application [as a Service](SaaS)
Platform [as a Service](PaaS)
Infrastructure [as a Service](IaaS)
Traditional 3 layer model - there are plenty of others!all ‘Cloud’… but DIFFERENT!

Opportunities exist at each level of the stack
But none are necessarily right for everyone.
cloudofdata.com
virtualise existing on-campus servers
JIT equipment for research groups, like Eli Lilly
aggregate data centres locally, regionally, nationally
‘Cloudburst’ for exam results, clearing, registration…
cloudofdata.com
build internal software on Platforms, instead of from the bottom up
replace suitable desktop software with appropriate Cloud apps
hand the pain of email and scheduling to YahoogleSoft, and go Web 2.0 for free

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?

Start simplewhy not give that demanding research group some EC2 credit instead of another server...
