+#### Can i deploy the application in multiple clusters?
+
+Absolutely. The repository knows nothing about the clusters the application
+will be deployed in, which is an advantage as you don't have to set the
+credentials anywhere outside the cluster(s).
+
+Deploying multiple times in different clusters will also help you reduce blast
+radius, is a good way to perform upgrades by redeploying the full setup and
+gradually moving resources to the new instance, and it's one of the
+alternatives to achieve high availability.
