One of the key requirements for Kubernetes in multi-cluster environments is the ability to migrate an application with all of its dependencies and resources from one cluster to another cluster. Application portability gives application owners and administrators the ability to better manage applications for common needs such as scaling out applications, high availability for applications, or just simply backing up applications for disaster recovery. This post is going to present one solution for enabling storage and data mobility in multicluster/hybrid cloud environments using Ceph and Rook.

Containerization and Container Native Storage has made it easier for developers to run applications and get the storage they need, but as this space evolves and matures it is becoming increasingly important to move your application and data around, from cluster to cluster and cloud to cloud.
