A number of people have asked if I would post links to videos that provide useful introductions to Cloud Computing. Believe it or not, there are many, many videos on this topic posted on YouTube, and I will post here links to those that I think might be useful if you are getting started with cloud computing.
Cloud Computing Explained
What is the Cloud? (now with pictures!)
A bit more technical: The Three Ways to Cloud Compute
A longer but very good introduction: Introduction to Cloud Computing
This last video is by Eli the Computer Guy. His channel at https://www.youtube.com/user/EliComputerGuyLive has a lot of interesting computer videos – well worth a look.
