Rackspace Cloud Sites would be a great example of cloud computing. It behaves like traditional shared hosting, with an easy to use control panel, but behind the scenes it can scale automatically with traffic and load. Obviously the database doesn't scale, but the frontend web servers do, all without user intervention.

EDIT: to the downmodders, please explain how Cloud Sites is not an example of cloud computing. It is a pool of shared hardware and software resources, the details and maintenance of which are abastracted away from the users, with the ability to automatically and infinitely scale up based on demand without user intervention, sold using an IaaS model?
