for people who need more 9s of availability on a single cloud provider, you have to start going multi-region. aws takes region isolation/independence very seriously, and along with geographic independence gives you effectively two entirely independent clouds which just so happen to have the exact same APIs. Some of the (really great) Netflix blog posts[0] have talked about multi-region services. If you do go multi-cloud, I would be wary of picking regions that are located very close to each other. While you'll obviously get independent code and (likely) independent deployments, you're still susceptible to issues correlated with the physical location.
