Juju makes things really simple.
But, like you, I'm not content to stop at simple. I'm always looking for ways to make things even simpler so that I have more time to work on tough problems (e.g. spreading Ubuntu in my city.)
Today my colleague Corey Johns pointed me to DHX, a cool plugin for Juju that he developed. Even simpler!
I hope you find this useful.
And please remember to thank Corey for his excellent work.
