• Stateful workloads are becoming more common in Kubernetes, and it is important to ensure consistency and accessibility of data as pods are refreshed or updated.
• The presentation covers volumes, persistent volume claims, storage classes, provisioners, and volume plugins as the fundamentals of Kubernetes storage.
• Participants are given the task of deploying an application with a front-end and back-end database, and troubleshooting any issues that arise.
• Debugging commands and resources are provided to assist with troubleshooting.
• The presentation also touches on storage performance and data protection.
• The slides and labs are available on GitHub and Instruct for further reference.

• Disaster recovery is important to ensure business continuity in case of data center loss.
• Regional disaster recovery involves two separate remote sites with high network latency and two separate Kubernetes clusters.
• Replication capable storage systems like Ceph/Rook can be leveraged to provide disaster recovery of workloads across clusters.
• A multi-cluster control plane is required to enable one-click disaster recovery solution for stateful workloads.
• Volume replication and volume application class are added to the standard CSI API to enhance capabilities.
• Dynamic provisioning requires creating a matching PV in the recovery site and connecting it to the replicated volume.
• Multi-cluster management requires equivalent cluster configurations and deployment of custom resources and operators on all clusters.
