Considering a true multi-cloud #Kubernetes cluster, how would you solve the storage? Is there a solution that allows you to use a single #StorageClass that maybe selects the appropriate StorageClass based on the location of the Pod? Like, if I build a Kubernetes cluster using both GCE and AWS, can I create a single StorageClass that I can use in both locations and it will choose the correct backing storage? How do others solve that issue?
