[chef] How do you manage multiple data centers

[Sascha Bates < >]

I'm about to embark on the multiple part of my multi-datacenter 
automation project and am wondering how people are accomplishing this now?

I currently have environments that mimic code promotion: dev/test/prod 
whatever.

My production environment is only used to pin cookbook versions and 
that's how I ensure promotion is controlled, by bumping the version in 
my environment.

Now that I'm approaching a situation where I need to make some design 
decisions, I'm wondering how people are managing data that vary by 
location and how they feel about what they're doing.  I'm aware of most 
of the ways to do something like this: environments, roles, data bags, 
whatevs, so I'm not in need suggestions on what I should do, but am 
looking for how you like what YOU'RE doing.

Thanks,
Sascha
