I wrote a demo application which registers google appengine instances in
chef [1], specifically the opscode
platform<https://cookbooks.opscode.com/users/new>,
upon startup. While the chef api is not 100% complete in jclouds, enough is
finished to start integrating.

The status page shows all the instances of the current google app engine
application, which are registered in the opscode platform.

When this seems to hesitate, it is probably google firing up a new instance,
which implies a new node registration. This is a simple demonstration.
More sophisticated applications can be built to use the databag concept in
chef to ensure that all dots between your cloud and non-cloud infrastructure
are connected [2]. You could even use the jclouds compute api to launch new
compute nodes (ex. ec2) and register them accordingly.
This demo requires a publicly available Chef 0.9.6 endpoint. If you are
using the Opscode Platform, remember that you get 5 nodes for free. Make
sure you clean up your nodes in the console when you are finished testing
[3].
I hope you like it!
