heat part 2

Here is part 2 of my Heat series. As before, I put in a suggested pub date for this coming Friday, but feel free to schedule for another date if you prefer. Thanks!
One comment:  You mention at the top of the article that the reader can try examples on Rackspace's private cloud.  One caveat.  I think our implementation of neutron only includes network,port,and subnet operations.  No floating IPs or security groups yet!
