Hi, I'm researching multi-cloud & multi-cluster Kubernetes. I couldn't found many sources regarding multi-cloud / multi-cluster Kubernetes storage. I would like to do failover of Kubernetes but need storage to be replicated to another cluster, of course with minimal downtime. Longhorn describes it's applicable for multi-cloud. What can you effectively implement regarding multi-cloud and multi-cluster use cases with Longhorn? I saw some sources about Yugabyte + Longhorn, but don't fully grasp the architecture and benefits. Restoring replicas should be faster, but what is the slower alternative?

You can utilize DR volumes on the second cluster, they will automatically keep restoring the latest backup on the shared backup store (S3 for example) So in a failover scenario you would have to activate the DR volumes so they become available for use. It's not yet a full fledged 1 click cluster failover, but scripts can be build around this to help with the failover work.

Thanks for the reply. I will look into DR volumes.
