Good start - I wasn't aware of the Litmus environment. The Animoto example is great, I love telling that story to people just starting to look into cloud computing.

To add to the large-environment roll call, here are the persistent server counts of some 100% cloud-hosted companies:

- Bizo: 100+ instances (I work here)

- Reddit: 100(?) instances ("256 Virtual CPUs" http://us.pycon.org/2010/conference/schedule/event/148/) - HNer jedberg runs this

- ShareThis: 250 instances (I worked here)

Longest-running instance I've had is at two years and still going strong.

reddit currently has 73 instances with this breakdown:

  25 c1.xlarge
  26 m1.large
  22 m1.xlarge

c1.xl are generally app servers, m1.xl are generally databases (either postgres or cassandra) and the m1.l are other stuff.

Is Reddit profitable?

We don't discuss that, but Conde isn't a charity. They wouldn't keep us around if it wasn't worthwhile.
