Nice! I've had a quick look to the jclouds bits and it looks great.

One little advice: I notice you are using the Hosted Chef (which IIRC
allows only up to 5 nodes in the free plan). If you're not planning to
pay for a hosted Chef Server or don't want to deploy your own one (you
might not want to add that piece to your architecture), you can also
consider using ChefSolo, which accomplishes the same configuration
management tasks without the need of a Chef Server. I wrote a small
blog post about it time ago [1]. You can check it to have an idea of
how it works, but it is quite an old post, so the links might be
broken and the code may have changed a bit.


In any case, good job!

I.
