What is profound, is that this allows you to build applications in a private (your data centre), public (Amazon’s or Rackspace’s cloud) or hybrid environment (a combination of both). It scales from your laptop, to the hundreds of servers in the data centre.
Finally, Cloud Foundry is open source. This is important to you guys out there because this should in theory allow you to federate (or connect) clouds together. The theory being that as you have a known code base and API set, you can readily do this task.
