Storage support?

[Jorge O. Castro]

Hi,

I was asking Clint some questions about Ensemble yesterday and we got
to talking about EBS (I was trying to determine how to make the
Mediawiki example be persistant and stored in EBS). I haven't hear
much discussion about storage an Ensemble so we thought it would be a
good topic for the list.

Here's a brainstorm of how I think it would work in the existing example:

...
$ ensemble deploy --respository=examples amazon-ebs
$ ensemble add-relation mysql amazon-ebs

I would then treat "amazon-ebs" as any other resource and set up
relationships to the storage and do other things like:

$ ensemble snapshot  // Point in time snapshot the entire thing to S3
$ ensemble backup blah   // Prompt me to snag my config and EBS stuff
so I can keep it offsite.
$ ensemble import blah    // Import the configs and EBS stuff back to EC2

Of course EBS is just one storage thing that is obvious, I'd want to
be able to treat a local SAN the same way, etc. Thoughts?
