Fred Prior, PhD, professor of radiology at Washington University in St. Louis, explained the concept at an RSNA 2013 session.
First, what is a “cloud?”
Think of it both as a set of services delivered over the internet as well as hardware and systems that provide those services which you don’t necessarily own. The services are provided through remote data centers that you will never see.
How does it work?
Many of the services are free, but for those that aren’t, you pay for what you will use. “For example I can temporarily use 1,000 machines from the Amazon cloud, use them for 10 minutes and give them back. I don’t have to actually buy 1,000 computers,” Prior said.
How do you see it?
One service model is when the software runs on a software provider’s infrastructure and you don’t know anything about it, you don’t manage it, but you simply “lease” it for a reasonable fee, he said.
