This is very cool stuff. Do you guys support (or do you plan to support) any type of cross-provider failover? I.e. if AWS goes down, auto re-deploy to Linode and handle the DNS re-routing, etc.?
Great point! Yes. We already configure DNS records for the stack (load balancers and servers). This allows us to take the same cut of code and build scripts and execute them against another provider like Linode or Joyent when AWS has issues automatically.
