Correct AWS gives you availability zones. It is easy to spin up a cluster over them and have little or no downtime.

But a burning data centre is just one problem. Another is e.g. the USE1 issue AWS had. AZ didnt help here. Having compute in a other region an rerouting might. But maybe we aint talking startup concerns here. (If you have a simple enough "app" just deploy again in another region and update dns.)
